Orch., p. 45), which Blume reduced to Luisia, being unaware that one of 
the two species was an Aérides of the cylindricum group. The other, 
brachystachys, Lindl., is a true Luisia, and it is curious that Lindley failed . 
to connect it with his Cymbidium section, Pseudovanda. Lindley, : 
however, subsequently reduced Cymbidium triste, Roxb. to La 
brachystachys, Blume, citing the figure Wight Ic., t. 1691, which — 
represents very well one of the Indian plants which has recently flowered 
at Kew. Roxburgh describes this as found on trees in the forests which — 
cover great parts of the Delta of the Ganges, flowering during the hot — 
season, and he describes the lip as composed of an inner, oval, concave” 
portion, joined to the lamina, or exterior reniform cordate part . + 3 
colour dark purple, with a few yellow spots. The Kew plant has the | 
ample concave hypochil of Wight’s figure, though the yellow is rather the 
_ remains of the ground colour on which the purple markings occur. 
A second plant, so far as can be told by the description, is L. microptera, 
Rchb. f. (in Gard. Chron., 1870, p. 1503), which is said to have been sent” 
by Col. Benson from Assam to Messrs. Veitch, and is described as having : 
straw-coloured sepals and petals, and a lip half purplish and half yellow. 
So far as I can see, the L. brachystachys var. flaveola, Par, & Rchb. f, — 
represents the same species, and in any case it does not agree with the 
preceding. 4

A third plant which has flowered at Kew is L. trichorhiza, Blume, the ‘ 
Vanda trichorhiza, Hook. Exot. Fl., i. t. we, 4 : 
Another species of the affinity is L. macrotis, Rchb. f. (in Gard. Clirols al 
1869, p. 1110), a native of Assam which flowered at Tottenham with Mr. 
. Day, whose drawing is preserved (Day. Orch. Draw., xiv. t. 24). This has 
green sepals and petals, and the lip wholly dark purple, with the hypochil

Cc close of the nineteenth century was marked by the introduction of 
several remarkable Orchids from Madagascar, two of which quickly. 
flowered, namely, Phaius tuberculosus and Cynorchis purpurascens, both o 
which had long been known to science. The flowering of the Phaits 
Gale the early days of 1901 caused some excitement, for it led to the 
oS that another species had been masquerading: in gardens undet 
this name for about twenty years. This latter, being without a name of 
its own, was called P. simulans, Rolfe, the flowers of the two being very 
similar, though the habit is very different. The history of the confusion, 
and a figure of the true plant, may be found at pp. 41-44 of our ninth
