514 OLXVI, AROIDEZ. (J. D. Hooker.) [Amorphophallus. 
Tuber a depressed bulbilliferous sphere 8-10 in. diam. Leaves 1-2, 1-3 ft. broad, 
segments simple or forked; leaflets oblong, acute; petiole dark green with pale 
blotches. Peduncle elongating in fruit ; sheaths linear-oblong. Spathe 6-9 in. across 
the orbicular-ovate obtuse limb, coriaceous or fleshy, variable in colour, green, usually 
with white spots below, greenish purple above, rough and dark purple within towards 
the base. Spadia very stout; fem. infl. cylindric, male subturbinate ; appendage 
dark-purple, sometimes 6 in. diam. Berries obovoid.—The geographical limits of 
this species are quite uncertain (owing to its being cultivated widely in the East for 
its tubers) ; and its synonymy is so mixed that I have withheld many sup 
synonyms and all habitats but India. The name campanulatus first appeared under 
Amorphophallus in 1834, in Decaisne’s paper cited above, as a Timor plawi 
and Roxburgh’s Arum campanulatum is there given by Blume as its type, toget he 
with Arum Rumphii, Gaud. in Freyc. Voy. Bot. 127, t. 34, &c. Whether either of the 
above is the Timor plant has never been discovered, but the appended descrip”. 
applies to Roxburgh’s species. In 1835 in Rumphia, Blume described, also as * o 
burgh's Arum campanulatum, and giving the same diagnosis as ln Decaisne) 
a very much larger Javanese plant, with a widely expanded spathe and longe 
spadix with a long conico-ovoid appendage. As Blume evidently all _ 
believed that he was dealing with Roxburgh’s Indian plant I think it best to o 
and limit the Indian species in accordance with his intentions and his and Roxbut sh 
diagnosis, and accept Dr. Prain’s name for the Javanese plant (A. Rex) “Brit 
being also a native of the Andaman Islds., comes within the pale of the m 
Ind. Flora. Wight gives copies of two drawings of Roxburgh's A. camp aiy 
latus, one, t. 785, the true plant; the other, t. 732, has a much larger b Wi 
campanulate spathe, 15 in. diam., with recurved margins, more like t this 
A. Rez, but with a short broad appendage 8 in. diam, and about as tall. à abt 
Wight says he finds no description in Koxburgh’s Flora; it is, however, no T 
to it that Roxburgh alludes in speaking of large plants with the appendage 6 in- 
lam, `

longer than the spathe, appendage elongate conoid sinuously waved.

ANDAMAN [srDs.; Narcondam Islds., Prain.—DisTRIB. Java. d tuber 
A very much larger plant than A. campanulatus, with the depress ments 
attaining nearly a foot diam., the leaf blade 5 ft. diam., the alternate wi in. 
6-10 in., the petiole attaining 5 ft., and stout peduncle 2-3 in. elongating el te re 
infruit. Spathe very broadly campanulate, 12-18 in. diam., with broad undu ^ 
volute margins, sometimes produced on one side into a prolonged pendulous prt 
red-purple, Spadiz, &c., as in A. campanulatus, but much larger, with a conica 
appendage 10-14 in. long, that rises high above the spathe, is broadly 
and purple-brown or pale and spotted with brown. .
