194 FOUK NEW GENERA OF AROIDE.*:. 



meuts 8 inches long, unequally pinnatipartite, each with 4-5 leaflets 

 varying from 1^-6 inches long, and from 1-2^ in. broad, all oblong 

 acute, bright green, unspotted, the lateral ones unequal-sided and 

 decurrent at the base. Peduncle as long as the petiole and simi- 

 larly coloured, 3-4 lines thick, terete, finely sulcate-striate. Spathe 

 2f inches long, pale greenish yellow, boat-shaped, shortly mucro- 

 nate-acuminate. Spadix 2^ inches long, the fertile portion terete, 

 the male part nearly three times as long as the female part. 

 Ovaries pale green, globose ; j)lacenta septa-like, projecting one-third 

 across the cell ; style very short, terete. Stamens pinkish (perhaps 

 whitish before dehiscence), spreading, anthers obcordate. Appendix 

 stij)itate, conical, obtuse, white, rugulose, wdth very numerous 

 crack-like fissures. 



Cochin China, (Island of Pliu Quoc ? ). Introduced by Mr. 

 Godefroy Lebeuf ; flowered at Kew, October, 1878. 



P. Lacourii, n. sp. — Petiole 12-15 inches long, terete, finely 

 sulcate-striate, light green or light olive-green, blotched with darker 

 green and pink. Middle segment of lamina with one entire oblong- 

 lanceolate acuminate leaflet, 4-5^ inches long, lf-2 inches broad, 

 narrowed at base into its 1-inch long petiole ; the lateral segments 

 pinnatipartite, each with about three oblong-lanceolate acuminate 

 leaflets 3^-5 inches long, 1:^-2:^ inches broad, the lateral ones oblique 

 at the base, but scarcely decurrent, all bright green marked with 

 scattered roundish white spots, the margins somewhat undulate 

 and slightly re volute. Peduncle like the petiole, but longer. Spathe 

 light green, boat-shaped, with the apical part slightly recurved 

 (always?), shortly and somewhat abruptly acuminate. Fertile 

 part of sj)adix terete, the male portion twice as long as the female 

 portion. Ovaries very pale greenish, depressed, globose, placenta 

 scarcely projecting. Style very short, terete. Stamens w4iitish, 

 turning darker when the anthers dehisce, less s^Dreading than in P. 

 anoinaUirn, the filaments of the lower flowers more or less united in a 

 column, anthers subglobose. Appendix white, stipitate, conical, 

 obtuse, divided by sinuous crack-like fissures into smooth, somewhat 

 brain-like convolutions. Odour none. — Amorphophallus Lacuurii, 

 Linden and Andre, in L'lllust. Horticole, 1878, vol. xxv. p. 90, t. 316 ! 

 Cochin China ^^Island of Phu Quoc.) Described from living 

 plants presented to the Eoyal Gardens, Kew, by Mr. Linden, one 

 of which flowered in May of this year. 



Ehektophyllum, n. g. 

 Spathe tube closely convolute, cylindric ; lamina boat-shaped, 

 subacute. Spadix monoecious, free, sessile, exappendiculatc, the 

 male and female portions closely contiguous, flowers without a 

 perianth, densely crowded,''' no neuter organs. Ovary subglobose, 

 or more or less angular by compression, one-celled, with one sub- 

 sessile anatropous ovule, seated at about the middle of a projecting
