11. SEOAMONE, R. Br.; Benth. et Hook. f. Gen. Ph ii. 746. 



Calyx 5-partite. Corolla small, rotate or campanulate, 5-lobed to 

 the iniddle or beyond ; aestivation variable ; lobes with fleshy sul> 

 marginal ridges and often a central one on their basal half, which are 

 decurrent on the tube within. Corona of 5 small or minute simple 

 laterally flattened or subulate lobes, arising from the staminal column. 

 Stamens arising from the bottom of the corolla; filaments adnate to 

 the style but scarcely connate with each other, or only at the very base ; 

 anthers small, erect or connivent around the dilated part of the style, 

 terminated by fimbriate membranous appendages which seem sometimes 

 to be connate. Pollen masses 20 (10 in all other genera except Toxo- 

 carpus and the Periplocece), very minute, globose, attached in fours to 

 the rather soft pale-coloured pollen-carriers, without caudicles. Style 

 usually produced beyond the dilated part and often exserted beyond the 

 anthers ; apical part (beyond the dilation) terete or clavate, obtuse, 

 broadly truncate, bilobulate or bifid. Follicles acuminate, smooth. 

 Seeds crowned with a tuft of hairs. — Climbing shrubs ; leaves opposite, 

 often pellucid-dotted ; cymes axillary and terminal ; flowers small. 



Species many, widely spread through the tropical regions of the Old World, ex- 

 tending into South Africa. 



The flowers of all the species here described, except S. erythradenia and S. gracilis, 

 are very similar in structure, and the ridges on the corolla-lobes being common 

 to them all are not mentioned in the descriptions. Mention of the dots in the leaves 

 is also omitted, as they are not always visible in diiferent specimens of the same 

 species, or even in different leaves on the same specimen; they are formed of minute 

 crystals of lime. 



The figures of the pollinia of Secamone in Engl. & Prantl, Pflanzenfam. iv. ii. 

 262, fig. 76, E. & J., are not to be relied upon, the relative position of the pollen- 

 carrier and pollen-masses being entirely erroneous, and of the other few figures that 

 have been published, not one, so far as I have seen, is correct. They are exceedingly 

 minute and therefore appear to have been badly observed. 



Besides the species described below, reference should be made to CynaiicTium 

 microstegium, K. Schum., and Gymnema crenatum, Klotzsch, which, from the de- 

 scriptions, may, I think, prove to belong to Secamone. 

 Corolla-tube \-l\ lin. long, at least § as long as the 

 lobes ; peduncles or cymes l-o-flowered.
