ORCHIDS AT KEW. a 
EVERAL interesting rarities are flowering at Kew, and among them 
S the striking Costa Rican Pleurothallis grandis, which was recently 
figured in the Botanical Magazine (t. 8553). It is one of the giants of the 
genus, and bears a long, one-sided raceme of some 27 brownish green 
flowers. Among other Costa Rican introductions of Mr. C. H. Lankester 
may be mentioned the charming little P. lateritia, which has been 
covered with a mass of its pretty reddish orange flowers, giving. a very 
pretty effect. Masdevallia gemmata, corniculata, inflata, muscosa, and a 
few others are also in bloom, and two plants of the interesting little 
Sigmatostalix radicans are flowering in profusion. Near by are examples 
of the pretty rose-coloured Oncidioda Charlesworthii, Miltonia Regnellii, 
Clowesii, and forms of M. spectabilis, the white Maxillaria venusta, 
Odontioda Charlesworthii and Diana, Odontoglossum Uroskinneri and 
grande, Cochlioda vulcanica, Calanthe Dominyi, the first artifical Orchid 
hybrid, and a few other interesting Cool house Orchids. 
In the Warm house are plants of Doritis pulcherrima, Arachnanthe 
Clarkei, Bulbophyllum Medusz, with several of its Medusa-like heads of 
flowers, B. lilacinum, B. crassipes, B. hirtum with numerous spikes, 
B. calabaricum, a small African species, and a lot of Cypripediums, among 
which C. niveum and its very pretty hybrid C. Vipanii, C. insigne Sandere 
and a clear yellow form of C. Sanactzeus may be mentioned. 
The Cattleya group produces a constant succession of flowers, and 
includes C. Bowringiana and its hybrids C. Brownii and Wendlandii, the 
latter bearing three fine spikes, one with six flowers. Other good things 
are C. Atalanta, Leliocattleya Nysa, Priam and. amanda, Brassocattleya 
Veitchii, Epidendrum ciliare and Hartii, with a few others. A plant of 
Dendrobium formosum now finely in bloom is'very effective. The Pleiones are 
beginning to bloom, and are among the’ most attractive of autumn-flowering 
plants. There are also several yellow-fowered Oncidiums, with the purple 
O. ornithorhynchum, one of the most distinct and attractive species in the 
genus when well grown. 
The collection is rich in botanical rarities, some of which may be found 
at any season, and one of the most interesting of those just over isa plant 
of the rare Cycnoches pentadactylon, C. chlorochilon being also in bloom 
at the same time. The quaint and striking genus Stanhopea is well 
represented in the collection, and among those which have bloomed during 
the summer we may recall the showy S. tigrina, S. Wardii, S. inodora, S. 
bucephalus, and the rare and very pretty 5. saccata.
