[ Cyperacea. 



Our plant has the inflorescence more elongated than Roxburgh attributes to his species, but all other points 

 seem to agree ; the filaments are quite glabrous. It differs from T. thyrsifiora of Blume by the sheaths 

 being ciliated or almost bearded at the mouth and along the margins.

We have not received the leaves: the inflorescence is quite the same with the Europaean plant.

We have seen only one specimen of the spatha and spadix without any leaves. 



1. Pothos Loureiri ; parasitica radicans, petiolis planis folium simplex lanceolatum latitu- 

 dine sequantibus longitudine excedentibus, florescentia subterminali, spatha lineari, spadice 

 longo cylindraceo tenui erecto. — Flagellaria repens. Lour. Fl. Coch. 1. p. 263. 



Very nearly allied to P. scandens, Linn. 



Ord. LXXXIX. CYPERACE^E. Juss. 



[The Cyperacem and Graminece form the most numerous and valuable part of the collections received 

 from Canton, and from the extreme vagueness with which the Chinese and East Indian species of both 

 orders have been usually described, it is necessary that they should be noticed more in detail than the 

 other families. For the following account of them we are indebted to our friend Prof. C. G. Nees von 

 Esenbeck of Breslau: and when we have added any species not elucidated in his MS., or have made any 

 additional observations of our own, we have inserted them within brackets. The mere specific characters of 

 most of the Cyperacea have been already published in Wight's Contributions.]
