Yerbendcece. 

 Our correspondent, Mr. Hogg, has raised some very fine ver- 

 benas, from seed received from Mr. Tweedie, collected by him 

 in Buenos Ayres. Those who have seen them, pronounce them 

 exceedingly beautiful. One called the V. araniuna, is of a deep 

 purplish color, with fine heads of flowers, a neat habit, and pro- 

 fuse bloomer. We shall speak of them more particularly, when 

 we are belter acquainted with them.

A curious, though not very ornamental, orchidaceous plant. 

 The flowers are produced in a sort of whorl, on a slender scape, 

 and are pendulous. "Nothing can be more singular than the 

 long strap-shaped sepals growing from one side of the flowers, 

 and almost bearing them down with their weight; they ofl'er a sin- 

 gular instance of the unequal force with which the phenomena of 

 development are exerted in one and the same flower." It is one 

 of the most extensively diffused of all epiphytal Orchidaceae. 

 The mode of treatment given at p. IS^will apply to this species; 

 a good portion of broken pots may, however, be mixed in with 

 advantage. [Bot. Reg., Feb.)

One of the most superb species of this most superb genus. 

 The specimen from which the drawing was taken, was grown at 

 Chatsworih, the Duke of Devonshire's place, the past year. 

 The flower sjiike does not generally produce more than three 

 flowers; but here are seven! Mr. Paxton considers it a "striking 

 illustration of the high degree of perfection to which orchida- 

 ceous plants may, and will eventually, be brought, when their 

 habits, and the treatment they require in cultivation, become un- 

 derstood, among the admirers of this, the most beautiful, and by 

 far the most interesting, family of plants, known in the vegetable 

 ■world. The flowers are large, the sepals, which are undulated, 

 are pure white, and the lip is elegantly shaded with purple. 



The cattleyas are easier to grow than some of the other gen- 

 era. They do not require so much heat as many of the tribe. 

 As regards the cattleyas, the majority err in keeping the tempe- 

 rature too hot and humid, and in giving loo much water when
