2094 THE ORCHID REVIEW. 
Of course it is now evident that it may occur wherever the two parent 
species grow intermixed, and on this point we have much to learn. It is, 
however, practically certain that the original record of New Grenada is 
erroneous. Williams’ Orchid Grower’s Manual (ed. 7, p. 612) states 
Guatemala, but we have no evidence that O. Lanceanum grows there. 
Messrs. Veitch remark :—‘‘Its habitat is virtually unknown to science,” 
(Man. Orch., viii., p. 41), and in the light of subsequent events the 
correctness of this remark can scarcely be called in question. If the 
origin of any of the plants that have “appeared at intervals in various 
Orchid collections in Great Britain,” since 1847, has really been known, no 
one seems to have thought the fact worth recording, and it is a subject for 
congratulation that the mystery has now so far been cleared up. It also 
explains to some extent why so beautiful a plant should have remained so 
scarce in collections, for natural hybrids are generally rare. 
PLEUROTHALLIS VILLOSA AND P. CILIARIS. 
THERE is a curious little section of the genus Pleurothallis, known as 
Lepanthiformes, owing to their resemblance in habit to the genus 
Lepanthes, and to this section the above species belong. A plant has long 
been cultivated in gardens under the former name, whose identity has been 
somewhat doubtful, and now materials have accumulated which, I think, 
enable the matter to be cleared up. In 1838, Lindley described a plant 
from the collection of Messrs. Loddiges, of Hackney, which was said to 
have been received from Mexico, under the name of Specklinia ciliaris (Bol. 
Reg., 1838, Misc., p. 31), which he afterwards (Fol. Orch., Pleur., p- 26), 
considered synonymous with P. villosa (Kn. and Westc. Fl. Cab. il., p- 78), 
a Mexican species which flowered in the collection of G. Barker, Esq-, of 
Birmingham, also in 1838. The identity of P. villosa, unfortunately, can 
only be ascertained from the description, which does not fit the original 
specimen of Specklinia ciliaris, in Lindley’s Herbarium. Another curious 
fact about this latter plant is that all the wild specimens known are from — 
Guiana and Trinidad, in the former of which it appears to be common, for 
which reason I believe the Mexican record to be erroneous. It is note 
worthy that the five following species described by Lindley were all received 
from Messrs. Loddiges as natives of Demerara, and it is highly probable 
that the present one had the same origin. P. villosa was described a5 
les chase rege and purple spotted flowers, and a plant answering bb 
Gas ng 100. is Howerlng in the Kew collection, side by side with the 
Plant, the latter having been sent home by Mr. E. im Thurn. The
