DORSTENTA MaAnnNI. ' 
Native of the Bight of Biafra. 
Nat. Ord. Morex. 
Genus Dorstenta, Plumier ; (Endl. Gen. Pl., p. 278). 
Dorstenta Mannii; caule erecto rigido subnodoso simpliciusculo tomen- 
__  toso, foliis petiolatis elliptico-obovatis acuminatis integerrimis v. sinuato- 
subdentatis utrinque glabrisad basin angustatam obtusis subcordatisve, 
stipulis minutis subulatis, pedunculis rameis tomentosis, receptaculis 
orbicularibus convexis margine processubus tentacula simulantibus

Discovered on the river Old Calabar, in 1863, by Mr. 
Gustav Mann, then the intrepid collector for the Royal 
Gardens, now a Forest officer serving in the Bhotan province 
of India, and by whom living plants were sent to Kew, 
which flowered in November, 1865. It has also been col- 
lected in the same locality by the Rev. W. Thomson, the 
discoverer of Clerodendron Thomsone and many other fine 
plants.* 
The genus Dorstenia is common in Tropical Africa, whence 
Mr. Mann has sent dried specimens of several species, but of 
these the present is the most singular, because of the long 
green processes slightly thickened towards the tips that 
fringe the receptacle, and pointing in different directions, 
resemble the tentacles of a sea-anemone ; in some herbarium 
specimens these are one and a half inch long, and much 
-Inore clubbed at the tip. 
* I may here state that Aristolochia Thwaitesii, Hook. (Tab. nost. 4918), 
supposed to have been sent by Dr. Thwaites from Ceylon, proves to be a 
native of Old Calabar, whence living plants have been sent by Mr. Thomson 
to the Glasgow Botanic Garden, and communicated to me by its curator, 
Mr. Bullen.
