Roxburgh does not describe or figure the seeds, and I have therefore described 

 these from the common Bengal form, which I assume is the plant he had under his 

 eye. 



2. B. echinosperma, Hook. f. leaves |-4 ft., flowers bisexual, 

 stamens 3, capsule 2-3 by in. terete, seeds yV in., spinescent with a long 

 filiform tail at each^end. Hydrotrophus echinospermus, Clarke In Journ. 

 Linn. Soc. But. xiv.r'8, t. 1.

BENGAL, CHITTAGONG, to MALACCA. DISTBIB. Sumatra. 



Sir W. Jones describes the flowers of Saivala as hermaphrodite, the stamens as 9, 

 and the seeds as mum-ate. Parish sends fine specimens from Moulmein, with flowers 

 and stamens as above, but no seeds. The Chittagong specimens gathered by myself 

 are flowerless; the leaves are 4-5 in. and capsulrs 2 in. on short scapes. Griffith's 

 Malacca specimens are not in flower, but have capsules 2-2| in. on very long scapes; 

 the leaves are 2 ft. long. Mergui specimens from Griffith in fruit only, have leaves 

 intermediate between those of the Malacca ami Chittagong forms. 



4. B. oryzetorum, HooJc.f. ; leaves 4-6 in., flowers 2-sexual, stamens 

 3, capsule 1-1^ by % in.,-scape very short, seeds -,'y in. sparsely tubercled, 

 tails or very short. Diplosiphon oryzetorum, l)cne. in Jacquem. Voy.

 both ends. B. octandra, Planch, in Tliw. Enum. 332.

Very near the Madagascar B. Aubertii, Rich., which is unisexual. 



** Leaves narrowed from below the middle to the base. 



6. B. lancifolia, Hook.f. ; leaves 4-6 in. linear-lanceolate, capsules 

 1-2 in. slender, scape as long, flower bisexual, stamens 3, seeds sparsely 

 tubercled, tail or very short. 



KFASIA HILLS, alt. 5000 ft., at Myrung and Nunklow, Clarke. 



The Myrung specimens have large seeds -^ in. long with no tails at all, and very 

 obscure tubercles ; the Nunklow ones have much smaller and more tubercled seeds 

 with short tails. 



7. B. Talboti, Hook.f.; leaves 4-6 in. linear-lanceolate serrulate, 

 flowers unisexual, capsules 1-2 in. by in.,, seeds very strongly echinate 

 with a short tail at each end.
