On the foliar organs of a new species of Utri- 
cularia from St. Thomas? West Africa.

With Plate XIX, 
I N examining a small epiphytic species of TJtricularia , sent 
me by Professor Henriquez, of Coimbra, from St. Thomas’ 
Island, I observed that it possessed spathulate leaf-like bodies 
resembling those of several other species. They were narrow 
and filiform at the base, broadening into a lamina about 
one-sixteenth of an inch in diameter, and apparently had been 
green in colour with three veins. Most of them had lost the 
apex, but in one specimen the body was terminated by a 
slender filiform process bearing utricles. Further examination 
showed that every stage occurred between the slender filiform 
process frequently branched and bearing numerous utricles 
and the flattened leaf-like lamina. In slightly expanded and 
flattened processes it was easy to see that the utricles sprang 
from their edge only and were not scattered over their sur- 
faces ; further, in the case of one branched process, while one 
ramus was flattened and leaf-like, the other appeared slender 
and utriculiferous. The most completely leaf-like bodies bore 
no utricles upon their edges, but where there was only a slight 
flattening the utricles occurred. 
A similar modification was figured by Professor Oliver 1 , in 
U tricularia J amesoniana , a small epiphytic species from the 
1 Journal of the Linnean Society, vol. iv. 
[Annals of Botany, Vol. II. No. VII. November 1888.]
