LIST OF NEW AND RARE PLANTS. 



FROM PERIODICALS. 



1. Bouvardia triphylj.a ; var. spi.kndens. — Scarlet Bouvardia. (Bot. Reg. 

 37, 1 840.) Cinchonacea, Tetrandria Monogynia. A variety of the old and 

 deseivedly admired B. triphylla. The flowers of tlie variety now noticed are of 

 a deep orange red, slightly tinged in places with yellow ; they are similar in size 

 and produced as freely as in the old species. Seeds of it were presented to the 

 London Horticultural Society by G. F. Dickson, Esq., and it has bloomed in the 

 garden. Dr. Lindley observes, it is a half hardy shiub, flowering from May to 

 October, if planted out in the American border. The roots will live in the open 

 border all winter, but should have a hand-glass or inverted garden pot placed 

 over so as to keep them dry. It is better, however, to take up the plants at the 

 end of autumn, pot them, or place them in boxes, keep them dry, till February, 

 then re-pot them. They very readily increase by cuttings of the roots, inserting 

 them in sand, allowing about one-third of the cutting above the sand. If placed 

 in a hot bed or bark pit, they speedily strike root and make good plants by May 

 to turn out into beds, &c. 



2. Brassavola venosa. — Vein-lipped. (But. Reg. 39.) Oichidacea?. Gyn- 

 andria Monandria. Imported by Messrs. Loddiges from Honduras. Sepals and 

 petals long, but very narrow, green. Labellum, the spreading lamina white 

 veined with dark; the claw of the Labellum is gieen. The flowers are de- 

 liriously sweet at night. Brassavolas grow best when they are suspended from 

 the roof or pillars, tied to a block of wood which has some pieces of turfy peat 

 secured to it, so as to keep the roots moist. 



3. Lopezia eineata. — Line-leaved. (Bot. Reg. 40.) Onagraceae. Mon- 

 andria Monogynia. It is a soft wooded gnenhouse shiub, which blooms very 

 profusely in January and February ; grows about three feet high, producing 

 numerous racemes of flowers, of a pale led colour. Each blossom is about half 

 an inch across. It is easily increased by seeds, and grows rapidly in any good 

 soil. 



4. L^lia rubescens. — Blushing, (Bot. Reg. 41.) Oichidacea. Gynan-

 of a delicate blush. Labellum at the edge blush, centre yellow, having a dark 

 chocolate eye. The flowers are produced freely on short racemes. 



5. Tradescantia tumida. — Gouty-jointed. (Bot. Reg. 42.) Commelli- 

 naceae. Alexandria Monogynia. A half-hardy herbaceous plant, but which
