Notes on Plants at Roraima. 179 
large number of plants of Brocchinia cordylinoides, still 
in its small Roraima, not in its larger Kaieteur form, as 
well as great quantities of the huge Stegolepis guyanensis, 
Kl. [No. 338] the Iris-like plants of which being provided 
with a great abundance of slimy matter, made walking in 
parts where they grew densely most difficult. The Broc- 
chinia too, grew in parts so densely that we had to walk, 
not on the ground but on the crowns of these plants, 
which, as we crushed them with our feet, poured from the 
axils of their leaves the remarkably abundant water which 
they retain — and very cold water it was — over our already 
cold feet. Nor must I omit to mention, though I purpose 
afterward to sum up my observations on the Brocchinia 
and on the various species of Utricularia, that in this 
bush belt a very few plants — I saw not more than three 
or four — of Utricularia Humboldtii, Schk. [No. 43], of 
the dark, Roraima form, were growing in the axils of the 
Brocchinia leaves, as at the Kaieteur. 
Two other very interesting plants appeared to us first 
jn this bush-belt, though we afterward found that they 
extended almost, if not quite up to the top of the moun- 
tain. One, Lisianthus (L. macranthus aff. [No 188]) 
was a large succulent-leaved herb, almost shrub-like, 
with very large, rich purple-crimson flowers centred with 
white — which would probably be a most valuable and 
gorgeous addition to our cultivated stove plants. The 
other was the most delicately beautiful, the most fairy- 
like, and at the same time for its size the most showy 
plant I ever saw. It was a new Utricularia which 
Professor Oliver has kindly named also after WiLLIAM 
Hunter Campbell. U. Campbellianum, Oliver, N. 
sp. [No. 187] grew among the very dwarfest mosses which
