Bahia, but probably of the greater part of Brazil. Like all the species with 

 similar habits, it grows freely in decayed vegetable matter, mixed with a little 

 pure loam, among quantities of potsherds, and it probably will soon become 

 common. Although it cannot be compared for beauty with C. tridentatum, 

 it is nevertheless a very iuteresting species ; the spots on the margin of the lip 

 are of the deepest and richest ruddy brown; while the horns of the column 

 may he compared to the fore legs of some spider, lurking in the bosom of the 

 flower, to seize upon the victims that may enter it. Catasetum is a Dame the 

 meaning of which is unexplained. 



8. Begonia heracleifolia, Parsnip leaved Begonia. Syn. Begonia radiata. 

 Monaecia, Polyandria. Begoniaceae. A native of Mexico, where it was met 

 with by the German travellers, Schiede and Deppe, in several localities. 

 It is a very free growiug hothouse plant, producing its rosy flowers in every 

 month of the year. All that it demands at the band of the cultivator is heat, 

 moisture, and a full exposure to the light. If kept too much in the shade, 

 the flowers lose the bright rosy tint which is natural to them, and with it their 

 beauty. Begonia, named in honour of Michael Begon, a French promoter 

 of Botany.

97 jlj, ManeUia glabra, Smooth Manettia. Syn. Manettia cordifolia. Tetran- 

 dria, Monogynia. Rubiaceae. This is an exceedingly elegant plant. Its 

 delicate and graceful form, and its long scarlet blossoms, contrasted with its 

 broad deep green foliage, render it one of the most beautiful objects that can 

 well be conceived. The plant appears to thrive best iu a mixture of sandy 

 peat and loam, is of easy culture, and is readily increased by cuttings, planted 

 in sand, aud placed iu artificial heat. Like most of the plants of the same 

 country, it will doubtless succeed well in the open border during summer. 

 The genus was named by Linn.sus, at the request of his correspondent 

 Mctis, after Xavier Manetti, Professor of Botany at Florence. 



% Artanena /imbriatum, Fringed flowered. Didynamia, Angiospermia. 

 Scrophulariis.e. Syn. Torrenia fimbriatum, Torrenia scabra. A native of 

 the bauks of the River Brisbane, at Moreton Bay, New Holland ; whence 

 seeds were transmitted, by the late Mr. C. Frazer, to the Edinburgh Botanic 

 Garden, where the plaut blossomed in 1831. Although usually treated as a 

 greenhouse plant, it will be found to succeed very well in the open border 

 during the summer mouths, producing its blossoms and ripening its seeds 

 freely. Flowers: blue, with violet streaks, about au inch long, vtry showy, 

 and an interesting addition to our gardens. It should be planted iu a mixture 

 of peat aud loam ; is increased by seeds, or by cuttings. 



3. Linaria circinata, Curve-leaved Toad -flax. Didynamia, Angiospermia. 

 Scrophularinas. This curious species was raised by Mr. Anderson, in the 

 Chelsea Botanic Garden, from seeds received from Buenos Ay res; but it 

 seems more probable that it is a native of Northern Africa, as most of the 

 species of the section of the genus to which it clearly belougs, are natives of 

 that country. The plant is apparently somewhat shrubby. Flowers : axil- 

 lary, solitary, sulphur coloured, dotted with dark red, very pretty. The plant 

 requires a light loamy soil, and may readily be increased by cuttings. It also 

 requires to be protected during winter, iu a pit. Linaria, from Linum, flax, — 

 having similar leaves. 



4. Lablavia vulgaris, Egyptian Haricot. Diadelphia, Decandria. Legu- 

 minosae. Syn. Lablab vulgaris, Lablab niger, Dolichos Lablab, Pbaseolus 

 niger, Dolichos purpurea, D. Bengalensis, D. albus, D. Lablab, Lablab uan- 

 kinicus, L. leucocarpus. This plaut is cultivated iu India, China, Egypt, 

 and many other countries of the East, and also in theWestludies, on account 

 of its pods, which are prepared and eaten in the same manner as Kidney
