from a broader, very undulate base, and a long pandurately trilobed acute 
lip. The colour is yellowish white, the sepals and petals spotted, and the 
lip beautifully veined with red-purple. It is much to be hoped that so 
striking and distinct a plant will soon be represented in European 
collections.

LAELIA PUMILA. 
I am surprised to see you say at page 321 that twin-flowered spikes on 
Lelia pumila are rare. I can only say I think my plants badly grown 
unless there are more twin than single spikes on them. This year, I am 
glad to say, there are only one or two spikes with single flowers, the rest, 
without exception, are “twin.” I imagine it is merely a question of growing 
them well. What causes “colour” in Orchid flowers, I wonder? The 
autumn has been unusually wet and chill with us, yet Cattleya labiata, 
Vanda ceerulea, and also Calanthe x Veitchii are deeper and richer in colour 
than they ever have been with me before. Nothing can be more lovely than 
Vanda ccerulea as it is at present with us.

MACRADENIA LUTESCENS. 
Tuis curious little plant has been cultivated periodically since 1822, when 
it appeared in the collection of Mr. Griffin, of South Lambeth, and was 
figured in the Botanical Register (VIII., t. 612), by Robert Brown. It has 
recently been re-introduced by Messrs. F. Sander & Co., and_ has, 
unfortunately, been again figured and described by Dr. Kranzlin under the 
erroneous name of Trichopilia multiflora (Xen. Orch., III., p. 152, t. 288, 
fig. 1). It is found in Jamaica, Cuba, Trinidad, Venezuela, and possibly 
elsewhere, and is a small plant with arching racemes of numerous reddish- 
brown flowers, with a three-lobed lip and curiously toothed column. It was 
also described by A. Richard, in 1853, under the name of Rhynchadenia 
cubensis (Sagra Fl. Cub., III., p. 248, t. 85). There are some half-dozen 
other species of this curious little genus, of which M. triandra, Lindl., and 
M. Brassavolz, Rchb. f., have appeared in cultivation. Another species 
must also be added, for on re-examination I find that Serrastylis modesta, 
Rolfe (Kew Bull., 1894, p. 158; Gard. Chron., 1894, xvi., p. 727, fig. 91), 
cannot be maintained as distinct from Macradenia. It may, therefore, bear 
the name of M. modesta, Rolfe. The affinity of the genus is with Notylia 
d Cirrhea. J
