Genera dubia vel ab ordine repellenda. 



Spirospermum, Thouars (Endl. Gen. no. 4690) : genus in ordinem dubium 

 propter embryonem exalbuminosum longissimum spiraliter tortum. 



Agdestis, Moc. Sess. (idem, no. 4684) : genus valde dubium propter ovai-ia 

 coalita et flores hermaphroditos. 



lodes, Blume (idem, no. 4689) : genus sine dubio ad Phytocreneas re- 

 ferendum. 



Meniscosta, Blume (idem, no. 4688) est certissime Sabia, Coleb. genus 

 anomalum dubife sedis. 



1 . Coscinium, Coleb., comprises four species from Ceylon and 

 India: — 1. C.fenestratum,Co\eh. 2. C. JViffktianum {CoW.Wight, 

 no. 2469). 3. C. Wallichianum (Wall. Cat. n. 4971 in partem). 

 4. C. Blumeanum (Wall. Cat. n. 4971 in partem). The three 

 last species are in the Wallichian herbarium under the name of 

 Cocculus Blumeanus, Wall. The structure of the seed, as figured 

 by Gaertner, well corresponds with that of the other genera of 

 this tribe, but the fenestrated appearance of the cotyledons re-
