In general appearance this species resembles much certain Ouruparia- 
(Uncaria)-species. It is an ally of G. Mariae Schltr. but has much larger 
differently shaped laeves.

flowering in July 1906. 
The first Philippine species of this hitherto Indian genus. 
Clemensia Schltr., gen. nov. 
The tribe of Marsdeniinae contains evidently yet a great number of 
new genera as is easily proved by the great number of them that have 
been of late published. Here I have to describe one that seems to be 
standing nearest to Telosma, but otherwise shows too certain affinities 
with Marsdenia. 
Calyx alte 5-partitus, foliolis suborbicularibus, margine minute cilio- 
latis. Corolla subrotata usque ad medium 5-fida, tubo late campanulato, 
lobis patentibus ovato-triangulis obtusis, Gynostegium late conicum corollae 
tubum subexcedens, sessile. Coronae foliola antheram duplo superantia 
et duplo latiora, rhomboidea, carnosa, dorso medio toro vel carina carnosa 
transversali ornata, intus ligula subulata, foliolum superante ornata. An- 
therae quadratae, appendice hyalina rotundata obtusa inflexa. Pollinia 
erecta oblongoidea, obliqua, translatoribus horizontalibus tenuissimis, 
retinaculo minuto basi affixis. Stigmatis caput subdisciforme, depresso- 
conicum. 
Planta terrestris, alte scandens, glabrata; caule ramisque laxe foliatis; 
foliis tenuiter coriaceis ovalibus, acuminatis; cymis umbelliformi-ab- 
breviatis, pedunculatis, plurifloris, rhachi mns illis Sarcolobi simili- 
bus; floribus mediocribus. 
Species singula adhuc nota philippinensis.
