TRICHOCENTRUM ALBIFLORUM, Rolfe.—A curious little species sent to 
Kew, from Mexico, by Mr. Finck. It flowered in the collection in September, 
1892, and again last year. It is allied to the Guatemalan T. candidum, 
Lindl., being the only other species in which the spur is reduced to a very 
short sac.—Kew Bulletin, 1893, p. 336. 
QNCIDIUM SANDERIANUM, Rolfe.—A handsome Peruvian species belong- 
ing to the section Microchila, and allied to O. annulare, Rchb. f., and O. 
monachicum, Rchb. f., which have the peculiarity that the petals remain 
clasped together by their crisped tips, forming a ring. The flowers are 
chocolate-brown and yellow, and bear some resemblance to those of O. 
falcipetalum, Rchb.f. Plants have recently been imported by Messrs. F. 
Sander and Co., of St. Albans, but have not yet flowered in cultivation.— 
Kew Bulletin, 1893, p. 337. 
SOBRALIA PUMILA, Rolfe.—An unusually dwarf species, native of Marajo 
Island, Brazil, of which a dried specimen has been sent to Kew by E. S. 
Rand, Esq., of Para. It forms small tufts, scarcely six inches high, the 
flowers being bright canary-yellow and produced in profusion. It is allied 
to the New Granadan S. fimbriata, Lindl.—Kew Bulletin, 1893, p. 337- 
CYPRIPEDIUM PoyNnTZIANUM, O’Brien.—This appeared among imported 
specimens of C. callosum, Rchb. f., in the collection of Reginald Young, 
Esq., of Sefton Park, Liverpool, after whose gardener it is named. It is 
suggested as being a natural hybrid between C. callosum and C. Hookere— 
the one from Siam, the other from Borneo, by the way. It would be 
interesting to know how the pollen was got over. From the description, 
it is probably C. callosum var, subleve, Rchb. f. (Gard. Chron., 1888, i. 
p- 331), and C. siamense, Rolfe (J.c., 1889, i. p. 192), the latter being the 
correct name, for the plant is quite different from C. callosum, Rchb. f.— 
especially in the shape of the dorsal sepal and petals—and is nearer C. 
javanicum, Rchb. f. C. callosum var. subleve, Rchb. f., is only vaguely 
defined as “a callosum without any calli on the disc,” but the type 
specimen, which is in the collection of R. H. Measures, Esq., The Wood- 
lands, Streatham, shows what was the plant intendedi—Gard. Chron., Jan. 
13th, p. 36.
