Doubtful Species. 



CBTPTOCOEYNE DALZELLII, Schott, in Bonplandia, Jahrg. 5 (1857) p. 221. 



This singular plant, of whicli Dalzell says he can make nothing, is represented in 

 Herb. Kew. by half a sheet of specimens, chiefly of fruit in various stages, and a 

 drawing. Dalzell says in a note attached to the sheet : " The leaf is lanceolate, without 

 petiole and apparently amplexicaul, the margin transparent and finally crenated ; 

 veins parallel ; surface woolly as if covered densely with cobweb. No stamens ; no 

 ovarium ; nothing but what is observed in the drawing. The perianth is fleshy and 

 what appears as the pedicel is solid." The fruit is ovoid, about 2 by 3 in. on a solitary 

 stalk. The seeds are 2-seriate, oblong, subtrigonous. The sheet is marked " BomJmy, 

 Dalzell," without further information as to locality. Fl. B. I. v. 6, p. 495 ; Woodr, 

 in Journ. Bomb. Nat. v. 13 (1901) p. 427. 



Excluded Species. 



CRTPTOCOETNE UNILOCULARIS, Kunth, Enum. v. 3 (1841) p. 13; Wight, Icon, 

 t. 774 ; Jackson, Index Kewen. v. 2, p. 661. Cryptocoryne Roxburghii, Schott, Prodr. 

 Syst. Aroid. (1860) p. 18 ; Dalz. & Gibs. p. 257 ; Engler, in DC. Monog. Phan. v. 2 

 (1879) p. 629. Ambrosinia unilocularis, Eoxb. Fl. Ind. v. 3 (1832) p 493. 



1 can find no evidence of the occurrence of this (a Coromandel plant) in the Bombay 

 Presidency. Dalzell [Bo. Fl. (1861) p. 257] mentions the plant as common, but he has 

 supplied no specimens of it, and I am of opinion that the plant he has described (I. c.) 

 as C. Roxburghii is C. retros-piralis, Kunth, of which there are specimens at Kew from 

 the Konkan and Deccan. There is not a single specimen in Herb. Kew. of Roxburgh's 

 plant, nothing but a drawing, and 1 believe that no specimen is extant. The plant 

 noticed in Woodrow's list from Poona proves to be C. retrospiralis. 



3. LAGENANDRA, Dalz. 



Aquatic herbs with the characters of Cryptocoryne, but with many 

 ovaries in close cycles at the base of the spadix. — Disteib. Species 5,
