Flora of Narcondam and Barren Island. 
post anthesiii caduoa, spongiosa, ragosa, valleciilosa, lutoa et brunneo-macalata : 
bacca 1—2-sperma, 0'75 poll, longa, hao 0'25-0'35 poll, lata, ovata, versus apicem 
angustata, carnosa, lutea; seminihus pendulis ovatis, triente basilar! e funiculo 
incrassato spongiosis, ceterum embryone corneo semini subconformi oartilageneis. 
This species resembles the Java form, or a variety, of Amorphophallus canvpan- 
ulatus [A. campanulatus Blume, Eumphia, i, 139. t. 32, 33, as opposed to Arum cam- 
panulatum, Eoxb , Hort. Beng., 66) in the conic-pyramidal shape of the appendix, but 
differs in other respects, more particularly in the leaf. It agrees with A. virosus 
Brown {Bot. Mag., 6978) in having the male and female inflorescence of about 
equal length, but in other respects is very distinct, for A. virosus has the dense 
flowered turbinate male inflorescence, and the short oblong appendix character- 
Stic of Eoxburgh’s Arum campanulatum of which it is probably only a form. The 
following brief diagnosis f may assist in indicating how very distinct the present 
plant is from the forms hitherto known :— 
Petiole hardly verrucose ; male flowers disposed spirally 
on an inflorescence not wider than the female : yellow 
pyramidal appendix (twice as long as broad, and) one- 
half longer than the combined inflorescences : (male and 
female inflorescences of equal length; spathe green con- 
colorous) . A. rex 
Petiole very verrucose; male flowers disposed spirally on an 
inflorescence much wider than the female : puriolish- 
brown appendix not so long as the combined inflore¬ 
scences : — 
Male and female inflorescences of equal length,spathe 
green suffused with purple, externally white spotted 
(oblong appendix not longer than broad) . A. virosus. 
Male inflorescence much shorter than the female, spathe 
pm’ple ooncolorous. A. campanulatus. 
Oblong appendix, not longer than broad . Arum campanulatum 
Eoxb. (India). 
Pyramidal appendix twice as long as broad Amorphophallus campan¬ 
ulatus Bl. (Java).J 
+ In connection with this, it may be mentioned that fhe Amorphophallus from the 
Coco Group, mentioned (Journ. As. 8oc., Beng., lx, 2, 333) as related to A. hulhifer and 
A. tuberculiger, has since flowered at Calcutta, and has proved, as was then anticipated, 
to be a very distinct species. As the authors of the other species, have indicated by 
the specific name the tubercle-bearing habit of the species, the writer proposes for 
this one the name ‘ Amorphophallus oncophtllus ’ Brain. The diagnosis between 
it and the two species for which it might be mistaken, is as follows:— 
Stigma sessile, spathe unconstricted, appendix equal in length 
to the combined inflorescences :— 
Female inflorescence shorter than the male . A. tuberculiger. 
Female inflorescence as long as the male .. A. bulbifer. 
Style distinct, spathe constricted slightly opposite the male 
inflorescence, appendix twice as long as the combined in- 
floi’oscences ... A. oncophyllus. 
J As this paper has been passing through the press, the writer has learned 
from Sir Joseph Hooker, that he identifies A. rex with Blame’s Java A. campanidatus.
