D. DaHLOUSieanuin, WalUch. — This is a beautiful large- 

 flowered evergreen species, with stoutish terete subfusiform 

 stems from four to eight feet high, elegantly marked with 

 reddish crimson ; it blooms from the old growths in April and 

 May, producing drooping lateral racemes of from five to seven 

 flowers. These flowers are large, fully three inches across, 

 with the parts broad and strikingly effective ; the ovate sepals 

 and much larger petals are of a pale lemon colour edged with 

 rose ; the lip is oblong, constricted in the middle, glandu- 

 larly villous and incurved in front, where it is whitish, the 

 base pale yellowish, marked on each side with a large oblong 

 purple-crimson blotch, the inner edge of which passes into 

 coloured whisker -like fringes ; it lasts four or five days in 

 beauty. This will grow either in a pot or basket, with moss. 

 D. Dalhousieanum has been exhibited with forty-three flower 

 spikes and four hundred and forty flowers, each four and 

 a half inches in diameter. — India.

D. Dearei, Rchb. f. — This handsome and desirable species 

 will take rank as one of the best white-flowered Dendrobes in 

 cultivation. It has stoutish terete stems two to three feet 

 high, bearing at the top a few close-set oblong-ligulate emargi- 

 nate leaves, and produces both terminal and lateral flower 

 racemes both from the old and new stems in the same way 

 as D. superbiens. The flowers, which last several weeks in 

 perfection, are nearly three inches across, and produced in 

 bold racemes of from ten to fifteen together ; they are pure 

 white, having a slight tinge of green in the throat. We saw a 

 plant of this recently in Sir Trevor Lawrence's collection with 

 three spikes on one bulb, and the effect of the butterfly-like 

 flowers produced in such quantities was most charming. —

 joints of the stem, many-flowered ; it blooms in March, April, 

 or May, and lasts from four to six days in perfection if kept
