1980 3(1) 4-12 Josef Bogner The genus Scaphispatha Brong. ex Schott (Buy)
ABSTRACT: The genus Scaphispatha was published by H. W. Schott in the year 1860 using this name given by A. Brongniart in the herbarium of the Museum National d'Histoire N aturelle in Paris on the sheet of d'Orbigny's type collection from Bolivia. Scaphispatha is monotypic and the single species, Scaphispatha gracilis Brongn. ex Schott, has been collected only four times in the last 150 years. Besides the Bolivian type collection by d 'Orbigny , the three others all came from Brazil; one from Para, and the other two from the same locality in Ceara. Since the inflorescence appears before the leaves, the leaves were unknown until 1977, when living tubers collected by myself in the Serra do Araripe, Ceara, produced leaves in cultivation in the Botanischer Garten Mlinchen. Now it is possible to give a full description of this rare aroid.

1980 3(1) 13-18 Mark D. Moffler Qualitative observations on tropical aroid cold tolerance (Buy)
ABSTRACT: As winter approaches each year, we all become concerned about protecting our tropical plants, especially those which are the most susceptible to cold damage. The fall of 1978 was mild in Tampa, with temperatures seldom reaching below 100C (500F). The mild fall gave many of us a false sense of security and steps for cold protection were put off until "tomorrow". It wa~ this unfortunate procrastination that lead to a premature study of cold tolerance in aroids. My initial idea was to test several landscape and porch plants for cold susceptibility, but unfortunately, I unintentionally tested 46 different aroids.

1980 3(1) 32-35 Simon J. Mayo Biarums for pleasure (Buy)
ABSTRACT: Among the general run of "bulbs" the genus Biarum undoubtedly falls into the "curiosity" category. With their low-slung inflorescences, glossy black-purple spathes and, let's face it, pretty powerful stench, the unwary lover of the more courtly Narcissus or Crocus is liable to recoil from the earthier appeal of Biarum with what must be reluctantly accepted as distaste, or in extreme cases, disgust.

1980 3(2) 39-48 Fred Dortort In the forests of Costa Rica (Buy)
ABSTRACT: Not long ago we had the opportunity to travel in Costa Rica for several weeks. We wanted to observe various tropical plants in their habitats, and we hoped that Costa Rica would be a good choice for our project. Aroids were one of the main groups we were looking for, and we found a large number of them.

1980 3(2) 49-54 Harald Riedl The importance of ecology for generic and specific differentiation in the Araceae-Aroideae (Buy)
ABSTRACT: It is Meusel's (1951) merit to have pointed out the significance of growth-habit for interpreting the evolution of a particular group of plants. In his paper he chose Araceae and Lemnaceae as striking examples to prove his point. While it is rather difficult to translate the German terminology he used for those plants which produce persistent parts above the ground, the term "geophytes" fits well for all those which persist with their subterranean parts alone. Among Araceae, rhizomatous and tuberous geophytes are known. Subfamily Aroideae is composed almost entirely of members of the latter group with the exception of plants growing in water or at least swampy ground, like Lagenandra. While, according to Meusel, intermediates between rhizomatous and tuberous geophytes are found in Colocasioideae, geophytes are rare or absent in the rest of the family.

This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: There are a number of ways of coexisting with monsters. One of them is to throw a party and invite the monster to be the guest of honor. During the years, Amorphophallus rivieri parties have come to be a Phillips family tradition.

1980 3(2) 58-60 Michael Madison Aroid profile no. 6: Anthurium andreanum
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Anthurium andreanum Linden, III Hort. 24:43, t. 271 (1877). Writing of his discovery a year later Andre remarked, 'it is without doubt one of the most beautiful, if not the most beautiful, of all my discoveries in South America,' (Ill. Hort. 24:43, 1877). He declined to give a precise locality for the plants in fear that other collectors would set out after them, this probably at the insistence of Linden, who jealously guarded his horticultural monopolies.

1980 3(2) 62-64 Marianne Knecht The uses of Araceae in African folklore and traditional medicine
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: In many countries of Africa much effort is now being put into research on medicinal plants, and accounts already exist which list those species that are used in some form or other in traditional African medicine. However, these accounts do not include the personal observations of botanists, who have gathered valuable information from local people during the course of their fieldwork. The following summary includes statements that I have obtained during my own field tours in Ivory Coast in West Africa.

1980 3(2) 65-68 R. J. Henny, Eleanor M. Rasmussen Growing and breeding Dieffenbachia (Buy)
ABSTRACT: At the Agricultural Research Center - Apopka we have been studying the breeding potential within the genus Dieffenbachia. One goal of this program is the development of new and better varieties of Dieffenbachia for commercial production in Florida. Another important objective is to study the reproductive mechanisms of fJieffenbachia and learn more of their biology and how it relates to all tropical plants in general and other aroids in particular. Such studies include research into factors affecting plant growth, flowering, pollen and seed production and storage and inheritance of various plant characteristics (leaf and petiole variegation, growth habit, etc.).

1980 3(2) 69-71 Simon J. Mayo Aroid symposium at Selby Gardens
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: At the end of March a unique event in the history of aroid botany took place in Sarasota, Florida, when the Marie Selby Botanical Gardens hosted a symposium on the Systematics and Biology of the Araceae. The conference, organized and directed by Dr. Michael Madison, marked the coming together of specialists on the family from USA, Great Britain, West Germany, Yugoslavia, Ivory Coast, Venezuela, and India, and represented the largest gathering of aroid experts ever held.

1980 3(3) 86-93 Richard C. Sheffer, William L. Theobald, Haruyuki Kamemoto Taxonomy of Anthurium scandens (Araceae) (Buy)
ABSTRACT: Anthurium scandens (Aublet) Engler is the most common and widely distributed of all Anthurium species ranging throughout the West Indies and tropical Central and South America. The habit is generally a small, vining, inconspicuous, usually epiphytic aroid. Specimens are occasionally cultivated for their attractive fruits which are sometimes eaten. In the past, the strong and flexible stems were used for making baskets and for tying together the framework of huts (Standley, 1937).

1980 3(3) 94-95 R. J. Henny, Eleanor M. Rasmussen Producing Dieffenbachia from seeds
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Although the flower structure and pollination method are known (1), difficulty in obtaining seed from selected crosses is a major reason that few hybrid Dieffenbachia exist. However, recent studies at the Agricultural Research Center - Apopka concerned with environmental factors affecting seed production in Dieffenbachia have led to greatly improved seed yields and made hybrid production easier.

1980 3(3) 96-97 R. J. Henny, Eleanor M. Rasmussen Stimulation of flowers in Dieffenbachia
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Dieffenbachia breeding has been hindered by sporadic flowering and the small number of inflorexcences per plant. In attempting to surmount this problem we initiated experments to see if it would be possible to control flowering using the plant hormone gibberellic acid (GA3,. The study was conducted on full-sized plants of Dieffenbachia maculata 'Perfection' grown in 6-inch pots. Treated plants were sprayed on their upper and lower leaf surfaces until runoff with either 250, 500 or 1000 parts per million GA3 while control plants were sprayed with water only. Ten plants were tested at each of the four GA3 levels and plants were maintained in a greenhouse held at 65-90oF temperature range. GA 3 was tested because it had previously been shown to induce flowering in many crops as well as some aroids (1,2,3,4).

1980 3(3) 98-100 J. Richard Shelton Aroid profile no. 7: Gymnostachys anceps
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Gymnostachys anceps R. Br., Prodr. F. Nov. Holl. I: 337. (1810). Gymnostachys is considered primitive in the Araceae family, and is not particularly related to Acorus calamus, even though, superficially it rather resembles A. calamus. No part of the plant - flowers, berries or leaves - has the characteristic odor. As one might recall, A. calamus leaves and stems have a characteristic sweet odor, and in fact, because of its odor, it is commonly called "sweet flag."

1980 3(4) 111-116 Niels Jacobsen Does Cryptocoryne ferruginea flower at full moon? (Buy)
ABSTRACT: In September 1978, Josef Bogner, Botanishcher Garten, Mtin~ chen, and I made a trip to Sarawak. The main aim of the trip was to study the Araceae of Sarawak, and among them the c. 12 species of Cryptocoryne that occur there. Coming to the end of our stay in Sarawak, we were, one evening, discussing the results of our stay and the question arose why we had not found Cryptocoryne ferruginea.

ABSTRACT: This past March, Dr. Gutierrez learned of a newly discovered stand of Agiaonema in the wilds of the province of Rizal, on the island of Luzon. His information came from Mr. Zach Sarian, a Filipino member of the Aroid Society. Directions as to the precise location where the plants were discovered were scanty, but, after gleaning as much information as possible, we set out in quest of their habitat.

1980 3(4) 130-132 Craig Phillips Aroids in the public aquarium
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: As every hobbyist knows, aquatic plants are both an aesthetic and a desirable complement to tropical fish tanks in the home. However, in the average public aquarium where individual tank capacity may be measured in thousands of gallons, decorative plants are usually either made of plastic or else notable by their absence, a fact on which visitors often comment.

1980 3(4) 134-143 Josef Bogner The genus Bucephalandra Schott (Buy)
ABSTRACT: The genus Bucephalandra Schott has been for a long time misinterpreted, because of an inaccurate description and an erroneous drawing by Schott (1858, 1860) showing a parietal placentation and the absence of flat staminodes between the female and male flowers. It seems that nobody since Schott has examined the holotype of Bucephalandra motleyana Schott, the type species. The holotype, Motley 404 (K), clearly shows a basal placentation and flat staminodes between the female and male flowers.
