THE MORPHOLOGY AND ANATOMY OF UTRICULARIA 
BRACHIATA , OLIVER. 
By R. H. Compton 
(Gonville and Cains College, Cambridge). 
[Text-Figs. 6 — 12 ]. 
TRICULARIA BRACHIATA was discovered by Sir J. D. 
Hooker in the Himalayas, and was briefly described by 
Professor D. Oliver 1 in 1859 , the diagnosis being as follows :— 
Scapo nudo gracillimo erecto v. descendente 2—4 unc. saepius 
1 -floro rarissime 2-floro, foliis reniformibus gracili-petiolatis, corollas 
labio inferiore quinquelobato, lobis lateralibus superioribus diver- 
gentibus linearibus obtusis, lobo inferiore centrale valde latiore 
subquadrato rotundatove plus minus abrupte obtuso. 
The material used in the present account was collected by Mr. 
I. H. Burkill in the Sikkim Himalaya, where he found plants 
growing among moss and foliose Jungermannieae on the trunks of 
Abies Webbiana at an altitude of 11,000 feet. 2 This material was 
preserved in spirit and sent to Professor Seward, who handed it to 
me for examination. 
Utricularia brachiata (Fig. 6) is a very small and inconspicuous 
species. A vertical flowering axis rises above the level of the 
mosses to the height of two or three inches and bears one or two 
flowers. A few reniform leaves of very delicate texture also rise 
into the air. Ramifying among the wet moss are the slender 
runners which bear tiny bladder-traps and minute tubers.
