Stn. — A. Sanderianuin. 



A. PELLUCIDUM, lAndley. — ^A bold-habited plant, making distichous tufts of 

 bright green shining oblong leaves a foot to a foot and a half in length, and 

 • producing long spikes of small white flowers which " are as delicate and trans- 

 parent as if they were flakes of snow fixed by frost in the very act of melting," 

 each part of the lip being studded and bordered with little crystalline elevations, 

 and the whole fabric of the blossoms as fragile as a thin plate of glass; it blooms 

 in winter, which makes it an acquisition at that dull season. It requires to be 

 kept in a warm house, and makes a good basket or block plant, being in growth 

 very much like a Phalaenopsis. — Sierra Leone.

A. PERTUSUM, Lindley. — This is a very distinct and pretty species, seldom 

 ' to be found, however, in collections. It somewhat resembles an Aerides in its 

 growth. The distichous leaves are lorate, with an obliquely bilobed apex, 

 rather narrow, channelled above, fleshy and dark green. The spike is pendulous, 

 longer than the leaves, secund, densely packed with white flowers, which have 

 a short pale yellowish spur about as long as the lip; it blooms during the late 

 autumn and winter months. — Sierra Leone.

A. PRIMULINUM, Rclfe. — A supposed natural hybrid between J., hyaloides and 

 A. citratum from Madagascar, which was flowered by Messrs. H. Low and Co. 

 The flowers are smaller and more crowded than those of A. citratum. Sepals 

 and petals of a pale primrose colour; lip pure white. — Madagascar. 



A. SANDERIANUM.— See Angkaecum modestum. 



A. SCOTTIANUM, Bohl}. f. — ^A very distinct and pretty species, which has 

 ' been introduced to this country by Sir John Kirk, and has been flowered by 

 ' the late Mr. Scott, of Walthamstow, after whom it is named. It has a terete 

 elongated rooting stem, and is the only Angraecum as far as we know with 

 terete leaves, which are subdistichous, semi-cylindrical, and subacute. The 

 flowers are produced from the axils of the leaves on one or two flowered 

 peduncles, sometimes as long as the leaves, and are large pure white, in shape 

 similar to those of A. elumeum, but rounded and abruptly mucronate at the 

 apex of the lip, the slender tapering spur six inches long and of a pale brownish 

 yellow colour ; it flowers in June and July. — Comoro Ides.
