A. Clowesii. The locality given, however, “ Sierra Maestre, Cuba ”, as pointed out 
by Lindley, is probably a mistake, and has arisen by some accidentai confusion of 
tickets. Schlim , bowever, collected A. uniflora in tbe province of Ocana, in New 
Granada, at an altitude of 1550 métrés, in August 1851. It is labelled “ A. virgi- 
nalis , fl. blanc pur ”, but this is only a variety of the same species. Warscewicz 
also met with it at the sources of the Maranon, in North Peru, and at Quindios, 
in tbe province of Tolima, in New Granada, from which latter source was obtained 
the plant figured in the Botanical Magazine. Tbere is also a specimen in Lindley’s 
Herbarium sent by Jamieson, probably from tbe neighbourbood of Quito; it 
is labelled “ Forests of the Andes at 7000 feet élévation ”. We hâve therefore 
evidence that tbe species is diffused along tbe Andes from Southern Peru to the 
north of New Granada, and possibly into Venezuela, for it was near Merida that 
M. Linden’s dried specimens of A. Clowesii were obtained, and a batch of living 
plants sent home by M. Linden contained ail the three species of Anguloa. 
For just half a century nothing seems to hâve been known about the genus 
beyond that contained in the original description, but in March 1844 a second 
species, A. Clowesii , appeared. In describing it Lindley remarked : “ At last a 
genuine species of the genus Anguloa , which has hitherto puzzled every one, has 
made its appearance in the collection of the Rev. J. Clowes, of Broughton Hall, 
near Manchester, who obtained it from Linden’s Columbian collections. ” In the 
following month the long lost A.uniflora flowered with Mr Barrer, of Birmingham, 
and later in the same year a third species, A. Ruckeri Lindl., blossomed with 
Mr Rucker, of Wandsworth. Ail three were obtained from M. Linden’s discoveries 
and it is somewhat singular that after the lapse of nearly another half a century no 
additional species should hâve been discovered. It is true that two or three others 
hâve been described, but they hâve proved to be nothing but varieties of the older 
species. Two other forms, however, are of considérable interest, namely A. X media 
Rchb. f. and A. X dubia Rchb. f. The first named is an artificial hybrid 
between A. Clowesii and A. Ruckeri (which by an oversight I described again as 
A. X intermedia), and singularly enough it has since appeared as a natural hybrid 
with imported plants. The second is a supposed natural hybrid between A. Clowesii 
and A. uniflora , which I hâve never seen. The other possible combination, 
A. uniflora with A. Ruckeri , does not appear to hâve been yet heard of. 
The variety here figured chiefly differs in having the transverse rosy bars 
on the base of the lip more developed than usual, and a little more colour about 
the crest; it is dedicated, at M. L. Linden’s request, it to M. Treyeran, a well- 
known French lover of Orchids.
