K. Alpinar The Araceae of Turkey (Buy)
 ABSTRACT: In Turkey the family Araceae is represented by 5 native genera [Arisarum Mill., Arum L., Biarum Schott, Dracunculus Mill., Eminium (Blume) Schottl. Besides exotic aroids widely grown as indoor ornamentals, Colocasia esculenta (L.) Schott is naturalized in two major cities (Antalya & Mersin) of the Mediterranean region and cultivated for their tubers as food; Zantedeschia aethiopica (L.) Sprengel is popular and grown outdoors mainly in the Aegean & Mediterranean regions for the cut-flower market. There are 36 native aroid taxa of which about 10 are endemic in Turkey. But as the native Turkish aroids exhibit significant variation in many morphological characters there are different approaches on systematics of the group. It seems that a biosystematic study will make a great contribution to the current knowledge of the Turkish aroids. The native aroids especially the representatives of Arum, have been found to be familiar to Turkish people and are used in traditional medicine & for food mainly in rural areas without paying attention to the kinds of the species. The details of the usage of Turkish aroids & their vernacular names, will be presented elsewhere.

Thomas B. Croat, Jane Whitehill, Emily D. Yates A new subsection of Anthurium section Calomystrium (Araceae) and five new species from Columbia and Ecuador (Buy)
 ABSTRACT: Subsection Rupicola, a new subsection of Anthurium section Calomystrium is proposed, encompassing nine rupicolous species. Descriptions and a key are provided for these species including: A. antrophyoides Killip, from Ecuador and Colombia, A. chocoense Croat and A. antioquiense Engler from Colombia, as well as A. amnicola Dressler, and A. sytsmae Croat from Panama. Five species, A. palacioanum Croat and A. weiffii Croat from Ecuador, and A. chocoense Croat, A. callejasii Croat, and A. vanderknaapii Croat, from Colombia, are described as new. Members of this group were previously thought to belong in section Porphyrochitonium because of their generally lanceolate leaf blades, and stems with short internodes. However, lack of distinct glandular punctations on blade surfaces and the ability to interbreed readily with other members of section Calomystrium indicate that this new group belongs in section Calomystrium, and has evolved without conspicuous posterior lobes typical of section Calomystrium, owing to their rupicolous habitat.

Peter C. Boyce Studies on Schismatoglottideae (Araceae) of Borneo IV: Preliminary observations of spathe senescence mechanics in Schismatoglottis Zoll. & Moritzi in Sarawak (Buy)
 ABSTRACT: Recent alpha-taxonomic studies of Schismatoglottis Zoll. & Moritzi provide a sufficiently stable framework to facilitate taxonomically robust multidisciplinary research, notably molecular phylogenetic, ecological and phenological studies including analyses of morphological adaptations to specialized ecology (in particular rheophytism), and comparison of mechanical processes linked to pollination strategies (notably spathe senescence). Such data will later be mapped onto molecular-generated phylogenetic trees in order to analyse their origins. The various processes by which the spathe limb is shed during or post anthesis is the subject here of a preliminary discussion. The significance of these data is reviewed in terms of the currently proposed informal infrageneric groupings.

Peter C. Boyce Studies on Schismatoglottideae (Araceae) of Borneo V: Preliminary ecological observations of Schismatoglottis (Araceae: Schismatoglottideae) on Matang Massif (Buy)
 ABSTRACT: The family Araceae in Sarawak comprises 31 genera, with more than 350 species, while on the Matang Massif alone 35 species in 14 genera are recorded to date. Of these Schismatoglottis Zollo & Moritzi is the richest and most diverse genus with nine species (Schismatoglottis asperata Engl., S. conoidea Engl., S. grabowski/ Engl., S. mayoana Bogner & M. Hotta, S. motleyana (Schott) Engl., S. multiflora Ridl., S. cf. neroosa Ridl., S. tecturata (Schott) Engl., S. wallichii Hook f) belonging to four of the informal species groups sensu Hay & Yuzammi (2000). Two of these nine, (S. mayoana and S. cf. nervosa) are endemic to Matang. Perhaps the most interesting aspect of these taxa is their ecological diversity. This paper will highlight these ecological aspects and speculate on the speciation processes involved in bringing about such diversity in a single genus.

K. M. Aravinthan, R. Kamalakanna, V. Narmatha Bai Callus induction and high frequency shoot regeneration in Amorphophallus smithsonianus Sivadasan -- an aroid endemic to India (Buy)
 ABSTRACT: Amorphophallus smithsonianus Sivadasan, an aroid endemic to Agasthiyamalai in the Western Ghats of Tamil Nadu, India, was selected for the present study. Investigations were undertaken for mass multiplication using tissue culture techniques. Among the different explants tested for in vitro culture, the laminar segments proved to be the best. MS medium supplemented with 2,4-D (2 mg/l) and L-glutamine (800 mgll) was found to be the best combination for induction of the callus forming the laminar tissue. Greening of the callus was best achieved in MS medium supplemented With SAP (2 mg/l}and adenine sulfate (30 mgll). Shoot-bud regeneration was achieved in MS medium supplemented with BAP (1 mgll) KIN (O.5 mgll) and adenine sulfate (30 mg/ 1). GA3 was found to be essential for the elongation of the shoot buds. MS + BAP (2mg/I) + KIN (0.5 mg/l) and AC (1g/1) proved to be the best combination for inducing maximum number of shoots from the green callus.

A. M. A. Sakpere, O. Adedeji Micropropagation of two Caladium species (Buy)
 ABSTRACT: Great differences occur in cell division and regenerative capacity between plants even within a single species. Therefore difference in callus induction and plant regeneration abilities of two Caladium species - Caladium bicolor and Caladium humboldtii was studied by culturing them on different combinations of growth regulators. Caladium humboldtii was found to be the more responsive genotype for callus induction while Caladium bicolor was the more responsive genotype for plant regeneration. Roots and shoots were more readily generated on corm explants in combinations of Kinetin and Naphtalene Acetic Acid (NAA) than in media containing different concentrations of 2,4-dichlorophenoxy acetic acid (2,4-D) and 1 mg/L Kinetin. Callus was generated on tubers of both species on media supplemented with 0.8 mg/L 2,4-D and 1 mg/L Kinetin.

A. M. A. Sakpere, O. Adedeji Somaclonal variation and its effect on foliar epidermal characters of Caladium humboldtii Schott (Buy)
 ABSTRACT: The ornamental value of Caladium species cannot be overemphasized and tissue culture is increasingly being employed in their propagation. Somaclonal variation is also exploited for the generation of new cultivars for the ornamental market. These variations essentially affect leaf morphology. Therefore, to see if there are corresponding anatomical differences, foliar epidermal studies were carried out on parent plant, Caladium humboldtii Schott, and a somaclonal variant (c. humboldtii 'Sakpere') derived from tuber explants cultured on full strength Murashige & Skoog's (962) medium supplemented with 3% (w/v) sucrose and 0.4 mg/L 2,4-D combined with 1.0 mg/L kinetin. Morphological differences observed were in the shape and colour of leaves of the in vitro derived plantlets. Foliar epidermal studies revealed significant differences in size of epidermal cells, stomatal index and stomatal size of the parent plant and the somaclonal variant. Circular-shaped stomata were encountered in C. humboldtii, these were sparse to absent in C. humboldtii 'Sakpere'.

Tony Avent Propagation of Amorphophallus by leaf petiole cuttings (Buy)
 ABSTRACT: It is our hope to expand the available information with regards to amorphophallus propagation by leaf petiole cuttings based on our experiments between 2004 and 2006. Leaf petiole propagation is certainly not a new idea but one that we felt deserved a more systematic experiment to refine our knowledge of the subject.

John Banta Growing aroids from seed: Little packages; big surprises
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
 ABSTRACT: Many aroiders have questions about the best way to grow aroids from seed. A simple question, but like most simple and quick requests, the answer is far from short and easy. Since a number of articles relating to other methods of propagation had been submitted for this issue, it seemed to be a good idea to round these out by inviting contributions from some of the most active members of the society. These were the responses, sometimes going further than the practical by reminding us of the importance of increasing and spreading aroids in collections since so much of their habitat is being lost.
