514 OLXvi. AEOiDE^. (J. D. Hooker.) [Amorphqphallus. 



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. PedancZe elongating in fruit; sheaths linear-oblong. Spathe 6-9 in. across 

 the orbiculai -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. Spadix 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 supposed 

 synonyms and all habitats but India. The name mmpanulatm first appeared under 

 Amor<phophallus in 1834, in Decaisne's paper cited above, as a Timor plant ; 

 and Roxburgh's Arum campanulatum is there given by Blume as its type, together 

 with Aram EumpMi, Gaud, in Preyc. Voy. Bot. 127, t. 34, &c. Whether either of the 

 above is the Timor plant has never been discovered, but the appended description 

 applies to Koxbuvgh's species. In 1835 in Eumphia, Blume described, also as Rox- 

 burgh's Arum campanulatum, and giving the same diagnosis as in Decaisne) 

 a very much larger Javanese plant, with a widely expanded spathe and longer 

 spadix with a long conico-ovoid appendage. As Blume evidently all along 

 believed that he was dealing with Roxburgh's Indian plant I think it best to name 

 and limit the Indian species in accordance with his intentions and his and Roxburgh's 

 diagnosis, and accept Dr. Prain's name for the Javanese plant (A. Re.v) which 

 being also a native of the Andaman Islds., comes within the pale of the Brit. 

 Ind. Flora. Wight gives copies of two drawings of Roxburgh's A. campanu- 

 latus, one, t. 785, the true plant ; the other, t. 7tl2, has a mnch larger broadly 

 campanulate spathe, 15 in. diam., with recurved margins, more like that of 

 A. Sex, but with a short broad appendage 8 in. diam. and aliout as tall. Of this 

 Wight says he finds no description in Koxburgh's Flora; it is, however, no doubt 

 to it that Roxburgh alludes in speaking of large plants with the appendage 6 in.

2. A. Rez, Frain mss. ; pedtincle very short and petiole rough, 

 spathe broadly campanulate with waved revolute margins, spadix much 

 longer than the spathe, appendage elongate conoid sinuously waved. A. 

 campannlatus, Blume Rumph. i. 139, t. 32, 33 {exd. si/n.). 



Andaman Islds. ; Narcondam Islds., JPrain. — Distbib. Java. 



A very much larger plant than A. campannlatus, with the depressed tuber 

 attaining nearly a foot diam., the leaf blade 5 ft. diam., the alternate segments 

 6-10 in., the petiole attaining 5 ft., and stout peduncle 2-3 in. elongating to 30 in. 

 in fruit. Spathe very broadly campanulate, 12-18 in. diam., with broad undulate re- 

 volute margins, sometimes produced on one side into a prolonged pendulous apex, pale 

 red-purple. Spadix, &c., as in A. campannlatus, but much larger, with a sinuate 

 appendage 10-14 in. long, that rises high above the spathe, is broadly conical 

 and purple-brown or pale and spotted with brown. 



3. A. dubius, Blume Humph, i. 142 ; petiole rough, spathe 3-5 in. 

 diam. subsessile campanulate with a rather long oblong tube and ovate 

 waved quite entire suberect or spreading limb, spadix shorter than the 

 spathe, appendage globosely ovoid quite smooth. Kunth Enum. iii. 32 ;

Leaves as in A. campannlatus ; petiole green with pale blotches. Peduncle very 

 short ; sheaths equalling the tube of the spathe, oblong, retuse, apiculate. Spathe 

 with the tube 3 in. long, green without and within ; limb ovate in outline, disk dull 

 dark purple with a bright green narrow waved border. Spadix 4 in., male infl. 

 nearly 1 in. diam. i fem. i in.; appendage Ij in. diam., chesnut-brown, anthers
