NOVELTIES. 
PLEUROTHALLIS MACULATA, Rolfe.—A small Brazilian species presented 
to Kew by Messrs. Shuttleworth, Carder and Co., of Clapham, which 
flowered in September, 1891, and again subsequently. It is allied to P. 
recurva, Lindl., of the section Brachystachyz, and has short racemes of 
purple flowers. The leaves are irregularly spotted with purple, in allusion 
to which the name is given.— Kew Bulletin, 1893, p. 334. 
PLEUROTHALLIS UNISTRIATA, Rolfe.—A very small species allied to the 
Guatemalan P. marginata, Lindl., belonging to the section Apode cespi- 
tosz, which has flowered at Kew on several occasions. Its origin is not 
recorded. The flowers are semipellucid white, with a purple mid-nerve to 
the petals and some similar colour on the lip—Kew Bulletin, 1893, p. 334. 
PLEUROTHALLIS PERGRACILIS, Rolfe.—A native of British Honduras 
which has been cultivated at Kew for a long period. It is allied to the 
preceding, though quite different in various structural details. The flowers 
are light yellowish white, with a purple mid-nerve to the petals—Kew 
Bulletin, 1893, p. 334. 
SCAPHOSEPALUM MICRODACTYLUM, Rolfe.—A singular little plant, allied 
to S. ochthodes, Pfitzer, which flowered at Kew during 1890, and again last 
October. The flowers are light greenish yellow with a suffusion of light 
purple-brown on the upper half of the dorsal sepal. The tails are very 
minute—hence the name.—Kew Bulletin, 1893, p. 335: 
MASDEVALLIA PUSILLA, Rolfe—The smallest-flowered species of the 
Saccolabiata group at present known. It flowered at Glasnevin in August, 
1891, under the care of Mr. F. W. Moore, and on subsequent occasions. It

densely speckled with dark purple-brown.—Kew Bulletin, 1893, p. 335.

Tropical Africa, whence it was sent to Mr. James O’Brien, of Harrow-on-

1889, and on subsequent occasions. It is allied to the well-known P. 
luteolay Hook., front Tropical America, and the Mascarene P. mauritiana, 
Spreng., of which it may be considered as the geographical representative.—
