Tuber 6 in. diam. or less, bulbilliferous all over. Leaves 1 ft. diam., 3-sect; 

 segments pinnatisect, lateral forked ; leaflets few, 4-6 in., linear, acuminate ; 

 petiole 1^-2 ft., green. Peduncle 12-18 in., stout, pale green streaked with 

 darker green. Spathe 56 in. by 4 broad, erect, broadly ovate, obtuse, concave, 

 loosely convolute below the middle, pale yellow-green, flushed with pink within, 

 dark purple at the base. Spadix very stout, stipitate, obtuse, as long as the spathe ; 

 male infl. much the longest ; neuters as large as peas, white. Anthers crowded, 

 very short, pores confluent. Ovaries scattered, globose, narrowed into a short 

 style ; stigma large, 2-3-lobed. P. dubium, Schott (Prodr. 125 ; Engler Arac. I. c.) 

 founded on a very imperfect spathe and spadix from Pegu (McLelland') is distin- 

 guished by its auther by the neuters being (in a dried state) turbinate with acute 

 margins all round. 



13. ARIOPSIS, Nimmo. 



Small tuberous herb. Leaves entire, peltate. Spathe small, cymbiform, 

 open (tube 0) persistent. Spadix shorter than the spathe, appendage ; 

 male fl. cylindric ; fern, adnate to the base of the spathe. Male fl. em- 

 bedded in the tissue of the spadix ; anthers connate in groups of 3, each 

 2-celled, surrounding a pore into which all open. Ovaries few, oblong, 

 1-celled ; stigma sessile, 4-6-fid ; ovules many, .orthotropous, 2-seriate on 

 4-6 parietal placentas. Berries 3-6-angled, many-seeded, stigmas stellate. 

 Seeds pendulous, albuminous ; embryo axile. 



This genus has hitherto been ascribed to Graham, in whose " Catalogue of the 

 Plants of Bombay and its vicinity" it first appeared, and where the letter N. 

 following the name was assumed by Schott and all subsequent authors to mean 

 " Nobis." It really means " Nimmo," Graham's coadjutor in the work, an excellent 

 botanist.

Tubers small, clustered. Leaves 1-6 in. diam., orbicular or cordate, tip 

 rounded or acute, membranous, glaucous beneath ; petiole 2-7 in., slender. Peduncle 

 1-4 in., very slender. Spathe 1 in., incurved, apiculate, violet with a green dorsal 

 ridge, paler within. Spadix decurved ; male infl. dark purple ; fern, green, stigma 

 yellow. A. protanthera , owes its origin to the fact, that whereas all the Himalayan 

 specimens then in Kew Herbarium from various collections showed that flowering 

 had preceded leafing by a considerable interval ; all those from the Western Ghats 

 showed that those processes had been contemporaneous. Specimens of the Himalayan 

 plant recently received from the Calcutta Herbarium, have invalidated the above 

 character.
