1. Ceelogyne flaccida, Drooping Caelogyne. Class, Gynandria; order, 

 Monandria ; natural order, Orchideae. The present genus contains no less 

 than twenty-one species, all natives of the East Indies ; but of which very 

 few are at present known in our European gardens ; and all that we do 

 possess we owe to the liberality of Dr. Wallich. From that source the 

 present species was derived, having been received by the Hon. and Rev. 

 Wm. Herbert, who again communicated it, with many other beautiful and 

 rare orcbideous plants, to the gardens at Wentworth House. There the 

 present species flowered in great perfection in February, 1811. Flowers: 

 raceme, eight to ten inches long, drooping, scentless ; sepals and petals, 

 pure white; labellum, white, blotched with yellow at the base of the middle 

 of the lobe, and at the base of the disk. 



2. BMia Shepherdii, Deep purple flowered. Gynandria, Monandria, 

 Orchides. This beautiful plant is a native of Jamaica, having been re- 

 ceived from that country by the Messrs. Shepherd, at the Liverpool Gar- 

 den, where it has been long cultivated. It has flowered there, as also at 

 Wentworth Gardens. Flowers, both within and without, of an uniform deep 

 purple colour, except the column, which is pale ; and the lamella of the disk 

 of the lip, wliich are dirty yellow. Bletia, from Louis Blet, a Spanish 

 Apothecary and Botanist. 



3. Arbutus tomentosa, Hairy Arbutus. Decandria, Monogynia. Ericinea?. 

 For the discovery of this interesting and very distinct species of Arbutus, 

 we are indebted to the venerable Menzies, who gathered it near the mouth 

 of the Columbia River. Mr. Douglas noticed it growing in rocky places. 

 It was presented to the Glasgow Botanical Garden from the London Hor- 

 ticultural Society, where it flowered in the greenhouse in December, 1833. 

 It is well worthy a place in every collection, bearing copious evergreen 

 foliage, and flowers of a snowy whiteness, well contrasted with the green of 

 the leaves. Arbutus, from Ar boise, austere bush, referring to the rough 

 fruit 



4. Euphorbia atro purpurea, Blood flowered Spurge. Monascia, Monan- 

 dria. Euphorbiaceas. The present species, though it cannot vie with the 

 E. splendens, or punicea, both of which bear such rich scarlet bracteas, is 

 ret well deserving a place in every greenhouse, from the deep blood-colour 

 of its bracteas and floral leaves, which present a strong contrast to the pale 

 glaucous hue of the rest of the foliage. It is a native of Teneriffe, dis- 

 covered by M. Broussonet, and sent to the Glasgow Botanic Garden, where 

 it blossomed in March. Euphorbia, from Euphorbus, Physician to Juba, 

 King of Mauritania. 



5. Cyminosma oblongifolia, Oblong-leaved. Octandria, Monogynia. Ruteis 

 affinis. A native of the colony of Port Jackson, inhabiting dark, shady 

 woods upon the rivers and immediate coast of New South Wales. It was 

 introduced to Kew Gardens in 1824. It is treated as a hardy greenhouse 

 plant, , and blooms in the summer and autumn. Flowers: in a corymb, 

 white, and pale yellowish green, making little show. Cyminosa, from Ku- 

 minon, cumin, or cumin-seed ; and osme, smell, — on account of its peculiar 

 fragrance. 



6. Calythrix virgata, Twiggy. Icosandria, Monogynia. Myrtaceas. Sy- 

 nonyms, Calytlu-ix ericoides. This plant was originally discovered by Mr. 

 A. Cunningham, in the hilly country around Bathurst, New South Wales, 

 and he introduced it in 1823 to Kew Gardens. A twiggy shrub, with gla- 

 brous stems and branches. It is a pretty growing shrub. Flowers: axil- 

 lary, small, mostly collected in tufts at the ends of the branches, white, very 

 fragrant There are two other species in the English gardens. Mr. Ci.n-
