32 THE -ORGHID- REVIEW. [JAN.-FEB., 1920. 
surface, both characters derived from B. Digbyana, which is entirely 
confirmatory of the parentage. The absence of the fringe is not surprising, 
considering how much it is reduced in a few other parallel cases. It is 
usually so much reduced that we have suggested recrossing with the 
Brassavola, in spite of its narrow petals and pallid colour. Intermediate- 
ness of character is an almost invariable quality of hybrid Orchids, though 
there are cases of characters being difficult to trace. The fact is, characters 
can be, and are, subdivided, and are sometimes present in the offspring as 
mere traces. We mention this, because some time ago we received a 
criticism that the argument about proportions was not sound, characters 
being either present or absent. The objection was based on Mendel’s 
experiments with peas, which we have shown to be a thoroughly exceptional 
group; in any case it is not a fact.—R.A.R. 
BULBOPHYLLUM DICHROMUM, Rolfe.—Another plant of this striking 
Bulbophyllum has appeared. The original bloomed at the Royal Botanic 
Gardens, Glasnevin, in February, 1907, and was shortly afterwards described 
(Kew Bull., 1907, p- 128),a figure also being given in the Botanical Magazine 
(t. 8160). The flowers are large and striking, and are borne in a lax erect 
raceme, the dorsal sepal and united lateral sepals being bright yellow, and 
the three-lobed lip purple, with a pair of acute side lobes, as in B. 
fuscopurpureum, Wight, to whicl it is nearly allied, though very different 
in colour. The Kew plant, whose identity was not known until it produced 
a couple of fine racemes, is believed to have been sent by M. Roebelen, from 
Bangkok, with a few other Siamese Orchids.
