It is possible that Gossweiler, 983, without flowers or fruits, from the forests of 
Mudobo, near Catambi, may belong to this species ; the native name is given as lucanygi, 
und it is said to have medicinal properties of use in stomach disorders.

reduced to minute scales. Inflorescences terminal, racemose or com- 
posed of numerous compact axillary branches; bracts and bracteoles

Preuss, 709, is a small and rather weedy specimen, but appears to agree with 
ann’s specimens. 7’. tenuissimum shows considerable resemblance to 7’. Stuhlmannit, 
and 7. fimbriatum.
