Pentstemon(r^/d.)barbatum {Penny) & ma-jus. This fine variety was 

 produced among a number of seedlings in 1827. It is a stronger grower, 

 the flowers are considerably larger, and of a finer colour. — P. glaucum

This exceedingly rare plant is limited, at present, to a few collections ; it 

 is now, however, perfecting seeds. It may, therefore, be anticipated shortly 

 to become more plentiful. It is a most desirable conservatory plant, pro- 

 ducing its fine red flowers nearly the whole year. Cuttings are rooted with 

 great difficulty.

Commelinedd. 

 Tradescantz'a (L.) crassula Link. Bot. Mag. 2935. This most singular spe- 

 cies of Tradescantia was received from Berlin in the spring of 1827, by Robert 

 Barclay, Esq., of Bury Hill (by whom it was presented to Messrs. Young), 

 in whose -collection it must have been prior to its introduction to the Edin- 

 burgh botanic garden. It is seen in the highest state of perfection in the 

 open border, in the summer months, where it evades the severity of our 

 clime, if protected by a mat in severe weather ; if kept in the stove or green- 

 house, it is in flower the greater part of the year. T. congesta D. Don. 

 Penny in Hort. Eps. By far the most beautiful of the hardy kinds, attaining 

 the height of 2 to 3 ft., producing crowded umbels of flowers of a vivid blue 

 colour. It succeeds in any kind of soil, but prefers peak It has the closest 

 affinity to T. virginica, but is specifically different.

 botanic gardens throughout the world. — Alpha. Jan, 1. 1830.
