D. VANNERIANUM, Echh. f. — This is a cross between D. monilifonne and 

 D. Falconeri, raised by W. Vanner, Esq., of Chislehurst. " The flowers remind 

 me of D. transparens. Sepals lanceolate with thin purple margin ; petals oblong- 

 acuminate white, with the apicular part of fine purple; lip most distinctly 

 rhombic; ground colour white, apicular and basilar part purple, disk light 

 sulphur-coloured and with a very fine great dark purple dash in the middle of 

 the upper part, running out by a dark purple line to the base '' (H. G. Reichen- 

 bach, in Oardenera' Chronicle, 3rd ser., 1887, i. p. 72). — Qarden hybrid. 



D. VEITCHIANUM.— See D. MACROPniLLUJi. 



D. VENUS, Bolfe. — A beautiful hybrid raised by Norman C. Cookson, Esq., 

 of Oakwood, Wylam-on-Tyne. It is the result of a cross between D. Falconeri and 

 D.nohile. "The raceme is two-flowered ; the sepals lanceolate, acute, bright rose 

 above, much paler below, 2^ inches long by f inch broad ; the petals are much 

 broader, acute, white, tipped with bright rose, and with a large deep maroon 

 blotch. Thus the flowers have much of the general appearance of D. Falconeri, 

 except that the yellow is absent from the lip. They are large and very showy, 

 and as the plant has now only flowered for the flrst time, it should develop into a 

 good thing. The leaf sent is narrowly lanceolate-linear, 3^ inches long by | inch 

 broad. Mr. Cookson remarks that the pseudobulbs are almost intermediate 

 between the parents, being semi-pendulous, and the nodes not nearly so much 

 swollen in B. Falconeri, with which it also agrees in its habit of producing new
