NOTICES OF BOTANICAL PUBLICATIONS.

scarcely known, except through a solitary specimen preserved in the 
Linnaean Herbarium, and which had been communicated by Thunberg 
to his illustrious preceptor. It was introduced from China by Mr. 
Reeves, and flowered at the Botanic Garden, Chelsea, in April last. 
It was named by Decandolle in honour of Mr. W, Kerr, a collector 
sent to China from Kew. 
2. Nemophila aurita. Ear-leaved Nemophila. A very pretty 
annual, discovered in California by the late Mr. Douglas, and ori¬ 
ginally introduced to our gardens from seeds transmitted by him to the 
Horticultural Society. 
It thrives in the open border, requiring no particular mode of treat¬ 
ment. The drawing was taken from plants in the nursery of Messrs. 
Allen and Rogers, Battersea. 
3. Rhododendron avhoreum; var. roseum. This splendid variety 
was raised at the late Earl of Liverpool's, Combe House, in 1819, by 
Mr. W. Smith, from Nepal seeds communicated by R. H. Jenkinson, 
Esq. One of the plants then raised blossomed for the first time in 
Mr. Smith’s collection at Norbiton Common, near Kingston, Surrey, 
where the drawing was taken in the beginning of April. Dr. Wallich, 
writing of this family of plants, imagines that, the two light-coloured 
varieties occurring at a higher elevation than the crimson-flowered 
kind,—may prove to be more hardy. This, with all the other sorts of 
rhododendron, are now arranged in the tribe Rhodoracerz of the natural 
order JEricacece of Don. In their native place they rise to the height 
of forest-trees. 
4. Ribes mcilvacium. Mallow-leaved Currant. An upright 
branched shrub, rising to the height of three feet or more, belonging 
to the natural order Grossulcicece, a native of California, -where it was 
found, and transmitted home to the Horticultural Society by the 
lamented Douglas. It is not so showy as the R. sanguineum, but is 
certainly worth cultivating in peat and loam soil among other shrubs. 
Paxton’s Magazine of Botany. The number for June 
contains :— 
1. Zygopetalon Mackaii. Mr. Mackays Zygopetalon. This 
plant was imported by Mr. Mackay, of the Dublin College Botanic 
Garden, from Brazil, about 1827, when it was soon after figured in the 
Botanical Magazine. The present beautifully-executed figure is from 
a plant which flowered with Mr. Bowe of Manchester last year. It 
may be classed among the most interesting of the order Orchidece, and 
succeeds with the management usually bestowed on this now fashionable 
tribe of plants.
