306 Ridley . — On the Foliar Organs of a 
Andes, and apparently allied to the one I describe below ; 
but he seems to have considered the spathulate leaves ending 
bluntly as quite distinct organs from the flattened bodies bear- 
ing utricles along their edge. I have seen the specimens of U. 
Jamesoniana in the Kew Herbarium, upon which Professor 
Oliver based his drawings, and find them exactly as figured. 
In them the two members seem at first sight different, but 
from our African specimen it would appear that they are really 
of the same nature, and are merely forms of the same member 
modified for different uses. 
If this be the case doubt may well be thrown on the foliar 
nature of these leaf-like bodies. For though they are somewhat 
regularly arranged on the little tuber from which they spring, 
yet as they are able to branch irregularly, some of the branches 
becoming spathulate leaf-like bodies with three nerves, and 
others remaining as utriculiferous threads, it seems impossible 
to consider them leaves, and they should rather be regarded 
as of the nature of stem-structures 1 . This view is confirmed 
by the African plant, in which one of the utriculiferous threads 
bears a small tuber, similar to the one from which it has sprung, 
at its apex, which again has emitted threads (Fig. I A). 
It is clear that an organ which can elongate and branch 
irregularly, and eventually produce a tuber, cannot be any- 
thing but a stem-structure. Hence it would appear that in 
the epiphytic species of Utricularia , at least, these leaf-like 
bodies are dilated phylloclades. 
U. bryophila , nsp. Planta humilis muscicola, tubere minuto. 
Phyllocladi longe petiolati, petiolis linearibus angustissimis, 
semiuncialibus, laminis loratis £ uncia longis jg uncia latis, 
apicibus longis filiformibus, utriculiferis, -J uncia longis, vel 
ultra interdum ramosis. Utriculi pauci minimi. Scapus 
1 2 uncia longus scabridus. Bracteae lanceolatae acutae paucae. 
1 I have added to the Plate a sketch of an utriculiferous thread from Utricularia 
pusilla , a Ceylon species, in which one branch is similarly converted into a spathulate 
phylloclade. I believe it to be a constant occurrence in many other species, but in 
herbarium material is not very easy to make out, owing to the fragility of the 
threads when dry.
