Lastly, I found a plant with a flower which, because of its form and colour, I at first sight mistook for a fritillary, like our " Snake's- head " (F. meleagris); but it was a new Lisianthiis, which Professor Oliver has named L. imThurniamis, Oliv., n. sp. [No. 306]. There grew many small but pretty and bright-coloured orchids—two new species of Fpidendrum (E. montigenum, Ridley, n. sp. [No. 322], and another [No. 304]); also a plant of a new genus of Cryptangiese named by Mr. Ridley Everardia (F. montana, Ridley [No. 335]). So the vegetation of the ledge continued to the top, and indeed actually extended over the top (woodcut, fig. 3). Fig. View at the point of entrance of the plateau on the top of Roraima. The general effect of the vegetation of Roraima, fitly rivalling in this respect the marvellously strange geological aspect of the place, is so strange as to be very difficult of precise description. It occupies more or less wide tracts, generally almost level, between the bare flat rocks and the groups of piled rocks which occupy the greater part of the plateau. In such places it forms a dense carpet of vegetation, which is generally but a few inches, never more than a couple of feet, in height, except where, from its general level, rise a few scattered individuals of the one shrub of any conspicuous height, Bonnetia Foraimce, Oliv., n. sp. [No. 330]—and that was never more than from 30 to 40 inches in height—or the many and very remarkable flower-stems of Abolboda Sceptrvm, Oliv. [No. 312], which, to my great delight, at that height still bore its beautiful blooms, the appearance of which I have already described. Through this carpet of vegetation ran many small streams; and even in other places much wate
