220 Notices of new and beautiful Plants, 



(now Plectocephalus) of Nuttall ; tlie clarkias, eschscholtzias, 

 and beautiful plants introduced by the lamented Douglas, from 

 California. They repay for all the less showy, though not less in- 

 teresting, species which have been figured for years. It is with the 

 same feelings of gratification that we behold the figure of the bril- 

 liant species of the genus Bartonia, which is now lying before us, 

 and which is, also, one of the latest and richest acquisitions by Mr. 

 Douglas, from California. It is a half-hardy annual, and flowered, 

 for the first time, in the London Horticultural Society's garden, in 

 July last. We cannot better convey an idea of its magnificence 

 than to quote the language of Dr. Lindley : — " It is only beneath 

 the bright sunshine that its splendid flowers unfold ; in the early 

 morning the plant is a shabby bush, with pale greenish-gray branch- 

 es and reedy leaves ; but, as the sun exercises his influence, the 

 petals gradually unfold, as if in acknowledgment of his power, till 

 every branch is radiant with gold ; and so metallic is the lustre of 

 the inside of the petals, that one would really think they must be 

 composed of something more enduring than the delicate and per- 

 ishable tissue of a flower." The flowers are about the size of the 

 Eschscholtzia, perhaps a little larger, but far more symmetrically 

 formed, and are very numerous on the extremities of all the 

 branches. Dr. Lindley thinks it a species which will be apt to 

 degenerate, especially if it is neglected, or not sufficiently supplied 

 with rich and moist soil, and he recommends that it should be 

 placed in a sheltered situation, as the branches are very brittle, and 

 liable to be broken by the wind; in a warm and sunny spot, or the 

 flowers will not be brilliant, and a rich soil, as " she is a gourmande 

 in her way, and, if starved, will not gain half her natural size ;" 

 moisture it must have, for " she is a thirsty sort of personage, and 

 would prefer the banks of a rivulet to the side of a hill." We hope 

 it will be speedily introduced. (Bot. Reg., Feb.)

TRISTA*N[A Smith (From the Greek word fAree and to stand; in allusion, as we presume 

 [Dr. Lindley], to the ternate disposition of the flowers and their stalks ; the three-forked in- 

 florescence of this doubtless very distint genus being strikingly diflisrent from all to which it is 

 nearly allied in the parts of fructification.) 



mactophy\la. AH. Cunningham JUSS. Lia.rge-leaved Tristauia. A tree growing to the height 

 of fifty or sixty feet ; requiring the protection of the green-house; flowers white; appearing 

 in August ; a native of New Holland. Bot. Reg., 1839. 



The specimens from which the drawing was taken, were con- 

 tributed by Richard Harrison, Esq., of Liverpool, where it flow- 

 ered in August last. The species grows to a large tree in its na- 

 tive climate. The plant from which the drawing was taken, 

 has, however, attained only the height of about four feet. It loses 

 its exterior bark like the -4'rbutus Andrachne. The leaves are 

 large and coriaceous ; the flowers usually appear in threes, and are 

 v/hite, with numerous yellow anthers. Desirable for a large con- 

 .servatory.
