V. VIOLACEA.— See Saccolabium violaceum. 



^ V. VITELLINA, Kriindin. — Dr. Kriinzlin remarks about this new species 

 that it resembles in every respect 1". coerulescens and especially its variety 

 Boxalli, but the flowers are very small and as yellow as the yolk of an egg. He 

 further describes it as being a gay-looking thing. It was first flowered in 1892, 

 in the Royal Botanic Gardens, Berlin. — Xative country not stated.

(Trihe Neottleae, snitviie Vanilleae.) 



This gen\is contains but a few species, all of which are climbing- 

 plants, with dark green terete rooting stems, oblong acuminate fleshj- 

 leaves. rarely wanting, and short axillary spikes or i-acemes of largish 

 flowers, which in most of the known species are dull-coloured and 

 uninteresting. The sepals and petals are free and spreading, the lip 

 adnate with its limb, broad and concave, and its base rolled around the 

 elongate wingless column. The species, which number about twenty, 

 occur in the tropics of both hemispheres. Vanilla is, perhaps, the only 

 genus of Orchidaceous plants which is of economic value. The fruits of 

 various species of this genus produce the vanilla of commerce so exten- 

 sively used for flavouring chocolate, liqueurs, ices, &c., and which is 

 considered one of the finest of aromatic perfumes. 



Culture. — These j)lants require strong heat during their growing 

 season, and should be potted in peat and sphagnum moss, and have either 

 some rough logs of wood to grow upon, or should be trained against a 

 wall. They produce roots freely from their climbing stems, and are 

 consequently readily increased by means of cuttings.
