 *iii&dum Lindl. bifid ^ El cu § d Pli.Y Manilla ?1837 D p.r.w. 



' A pretty species of this interesting genus of epiphytes, with 

 the habit of a small vanda. It was received by Messrs. Lod- 

 diges from Manilla, where it had been collected by Mr. Cuming.

are'spontaneously thrown off from the flower shortly after they have expanded, just as leaves are 



thrown off the stems of many of these plants, when they receive a sudden check, and then the 



petals and labellum only remain to constitute the flower.) Orchid&cets.

*prolifer\xs Lmdl. proliferous £ i | cu 1 au P N. S. W. ... S r.l Bot. reg. n. s. t. 8. 



For this beautiful Swan River plant, as for several others, 

 our gardens are indebted to Robert Mangles, Esq., of Sun- 

 ning Hill. The fringed margin of the petals in this species, as 

 in all the others of the genus, form a remarkable feature, and 

 one which will cause some species or other of the genus to be 

 much sought after in collections. T. proliferus is rather difficult 

 to keep ; for, in winter, the least frost or wet destroys the roots. 

 It may be grown either in pots in a green-house, or in the bed of 

 a pit, from which the frost ought to be completely excluded. 

 When done flowering, and the seeds are ripe, moisture should 

 be withdrawn, in order that the root may have a period of rest.

 22726a *Perrin?2 Lindl. Perrin's j^ 123 or 1 ... P Brazil ... D p.r.w Bot. reg. n. s. t. 2. 



This species is a native of Brazil, and is not unlike C. labiata, 

 although inferior to it in beauty. It has been named after Mr. 

 Perrin, Mr. Harrison's intelligent gardener, under whose care so 

 many fine South American epiphytes have been for the first time 

 brought into flower in this country. " Like the rest of the 

 genus, this requires to be grown in a moist stove, the tempera- 

 ture of which may be kept from 60° to 70° of Fahr. in winter, 

 and from 70° to 90°, or even 100°, with sun heat, in summer. 

 It is propagated, like the other plants of this order, by divisions 

 of the rhizoma, or rootstock, with a stem adhering to them. The 

 soil should consist of good peat, broken or cut into pieces, 1 in. 

 or 1 ^ in. square. The pots should be about half-filled with 

 broken bricks, or something of that description, to carry off 

 superfluous water; and, if they are plunged in a tan-bed, this 

 will allow the heat to rise more freely than if the pots were 

 wholly filled with soil. It is of the greatest importance to pre- 

 serve and encourage the roots ; and, as they are generally pro- 

 truded near the surface of the soil, it should be raised several 

 inches above the level of the pots, in a pyramidal form, in order 

 that they may liave full room to push out." {Bot. Reg., Jan.)
