  "Arum trilobatum"???
From: Ellen Hornig hornig at Oswego.EDU> on 2001.12.18 at 15:22:00(7947)
Hello, all. I need some help here, being woefully ignorant of the
tropical
aroids. I bought an old Curtis print on eBay (#339, dated 1796) depicting
"Arum trilobatum" (Arisarum amboynicum is given as a synonym). The plant
is described as native to Amboyna (???) as well as Ceylon. Do these names
ring a bell with anyone? The text accompanting the print does not give
dimensions, but indicates the leaf is more sagittate than otherwise (the
lobes are fairly prominent, hence the specific epithet), and
describes the plant thus: "It is one of the least of the
tribe....distinguished by the rich, brown, velvety appearance of its
flowers; the length of its tapering spadix, which on its lower part is
full of little cavities, and resembles a piece of metal corroded by long
exposure; and by the intolerable stench which the whole of the flower, but
more especially the spadix, sends forth." The picture shows the spathe to
be bent back towards the ground somewhat, and the spadix to be - um -
heartily erect. I can e-mail a scan to anyone who thinks they can be helpful.

If, BTW, anyone collects old plates of tropical aroids, feel free to get
in touch (PRIVATELY)...it could be arranged. My own interests lie with
the hardy ones.

Thanks in advance,
Ellen

This is Typhonium roxburghii, a species widespread central and
east SE Asia but reaching in S India and Bangladesh. It has been
introcuced into SAmerica and E Africa.

Dear Ellen,

What was that about erect? Somehow, based on an incident in the past, I
wouldn't have figured that you would ever use that word..................
;-)

Now to the matter in....errrr, at hand.....

The name Arum trilobatum of Linnaeus, if CORRECTLY applied should refer to
Typhonium trilobatum BUT in the days when the plate was prepared that you
have bought, such correctness was not the case. The name was idly misused
for the plant we now know as Typhonium roxburghii, a pan-Asian weed and
hence can be found on Ceylon (Sri Lanka) and Amboina (an island of the
Moluccas). The name "Arisaeum amboynicum" daets back to the Dutch botanist
Rumphius who used this name in 1747 and also refers to Typhonium roxburghii.

All this and more in: Nicolson, D.H. & M. Sivadasan, 1981. Four frequently
confused species of Typhonium Schott (Araceae). Blumea 27: 483 - 497.

Cheerio,
Wilbert
