these Wageneria is that into which may for the present 
be placed, though differing from that section in habit and 
foliage, and in having four male perianth-segments. In 
habit it approaches nearest to B. dichotoma, J acq. Ie. t. 619. 
Mr. Watson informs me that B. umbraculifera was im- 
ported amongst some Orchids from Brazil by Messrs. F. 
Sander & Co., from whom a plant was obtained in 1893, 
and that by far the greater majority of the flowers 
throughout the plant are male. It flowered in the « Begonia 
House” of the Royal Gardens in March, 1895. 
Descr.—Stems six from the root, four feet high, quite 
simple, erect, half an inch in diameter, terete, smooth, pale 
brown, leafing towards the tip only, marked with narrow

obliquely orbicular, retuse, one side more or less produced 
into a broad, low auricle, bright pale green and glossy above, 
pale beneath, with eight to ten radiating nerves; margins 
obscurely denticulate. Stipules an inch long, green, cadu- 
cous. Cymes large, supra axillary, dichotomously branched ; 
peduncle many times longer than the petiole, confluent at 
the base with the internode above it, rose-colrd. ; branches

small corymbs, chiefly male, with a few female and bi- 
sexual flowers. Male jl. one inch. diam., ebracteate ; 
sepals 2, orbicular, white; stamens about twenty, in a 
compressed bundle; anthers oblong, obtuse, longer than 
the quite free filaments; (very rarely an imperfect sub=
