HLOR#A is a rather large South American genus of terrestrial 
Orchids, of which several species are decidedly showy, though they are 
seldom seen in cultivation. It is structurally allied to the northern 
Cephalanthera and Epipactis, and has its headquarters in Chili, a few 
species extending south to Patagonia, and a few others being found in 
Argentina and South Brazil, while there is a solitary outlying representative 
in the Falkland Islands. Of the latter a dried specimen has been sent to 
Kew for determination by Major F. J. Newnham, of Hove, Sussex, and as 
the history of the species has been much confused a note may be of interest. 
The species has been known for over a century, having been figured in 1770 
by Pernetty (Hist. Voy. Malovines, il., p. 54, t. 8, fig. 5), under the name ot 
Satyrion. The author remarked that he had been unable to discover the 
flowers of the plant, though he had seen several of every size, the highest 
having capsules filled with seed, and a kind of tuft at the extremity 
resembling a cluster of dried petals of a reddish cast, and that the seed was 
a very fine red dust. It was also mentioned by Gaudichaud in a list of 
Falkland Island plants, in 1825, under the name of Arethusa lutea (Amn. Sc. 
Nat., ser. I, xv., p. 100), the author being under the impression that it was. 
identical with Serapias lutea, Comm., a native of the Straits of Magellan. 
The mistake was pointed out four years later by Dr. Urville, who described 
and figured both species, calling the Falkland plant Chlorza Gaudichaudii 
(Duperr. Voy. Bot., p. 189, t- 44, fig. A), and remarking that it was frequent 
in theislands. It was subsequently collected there by Wright and by Sir 
J. D. Hooker, the latter remarking (FJ. Antarct., ii., p. 350) that it is not 
uncommon in moist pastures, varying a good deal in size and in the breadth 
of the leaves. Ten years ago the same plant was again described by 
- Kranzlin under the name of Chlorea falklandica (Engl. Jahrb., xliv., Bezbl. 
IOI, p. 5) from material collected by Skottsberg in two Falkland localities. 
The identity with C. Gaudichaudii has since been pointed out by the 
collector himself (Kungl. Svensk. Vet. Akad. Handl., 1., n.3, p- 23, t. 1, fig. 
7-10), who records it from four different localities. He remarks that the 
flowers, though comparatively large, are inconspicuous, and that they are 
cleistogamous. It may be added that Lindley, and afterwards Kranzlin, 
gave the Straits of Magellan as a locality of C. Gaudichaudii, but the 
Magellan plant really belongs to C. Commersonii, Duperry (Hist. Voy. Bot., 
p. 191, t. 44, fig. B.), now known as Asarca Commersonii, Hook f., but as 
this was originally based on Serapias lutea, Pers. (Syn. ii., p. 513) the name 
Asarca lutea must be applied under the Vienna Rules. Major Newnham
