DESCRIPTIVE LIST OF NEW PLANTS. 
Desmotrichum, a section which it seems better to limit to the 
species whose lip is broken up into a brush. 
The present species, which was imported from the East Indies 
by Messrs. Henderson, is extremely handsome. It differs from 
D. densiflorum , in its many-angled pseudo-bulbs, small bracts, and 
curiously fringed, pubescent, not shaggy lip ; from D. Griflithia- 
num in its round emarginate fringed lip; and from D. aggregatum 
in the same respects, as well as in its great club-shaped, many¬ 
leaved pseudo-bulbs. It has bright deep yellow flowers, produced 
on a lax pendent raceme in the manner of D. densiflorum. — Bot. 
Reg. 36-47. 
Cleisostoma ionosmum (Lindley). A native of Manilla, whence 
it was sent to Messrs. Loddiges by Mr. Cuming. It flowered 
in the Hackney Nursery in March 1844. The flowers are in an 
open panicle, about an inch across, flat, with five obovate, equal, 
obtuse lobes, yellow, with cinnamon brown blotches; the lip is 
white, with a few red streaks, three lobed, with the basal lobes 
acute, and smaller than the middle one, which is cordate, tri¬ 
angular, acute, and much larger than they are. The flowers 
smell pleasantly of violets.— Bot. Beg. 41-7. 
Dendrobium mesochlorum (Lindley). This beautiful species 
allied to D. crumenatum , and resembling it in habit, although 
destitute of a bulbous base to its stems, was imported from India 
by Messrs. Yeitch, and exhibited by them at the last meeting of 
the Horticultural Society where it gained the medal. It is not 
discoverable among any of Blume’s Onychiums, of which it would 
be one. The flowers are white, of the size of D. crumenatum, 
with a violet spot at the end of the petals and lip, and with a 
green stain in the centre of the latter. They have a faint but 
agreeable odour.-— Bot. Reg. 
Dendrobium Egertonia. This species has for some time been 
cultivated by Sir Phillip Egerton; it is very near D. mesochlorum, 
but the flowers are not half the size, the sepals are pale pink 
outside ; there is very little appearance of a purple stain on the 
tips of the petals and lips, and the middle of the lip is dull yellow, 
not green. There is, moreover, no tubercle at the back of the 
point of the spur, and the lip is not fringed except at its base. If 
it is less showy than D. mesochlorum , it is not on that account less 
valuable, for its flowers are delightfully scented towards evening.
