Asclepias obtiisifolia and variegata. Proceeding towards Troy, on 

 .the banks of the Hudson, great quantities of Kalmia angustifolia, Cor- 

 nus florida, Lupinus perennis, Andromedas, Vacciniums &c., occur- 

 red. In an extensive forest, chiefly composed of small trees, and 

 much entangled with Smilax, or green brier, through which the party 

 proceeded with great difficulty, Cypripedium spectabile covered large 

 patches, with Arum triphyllum, the latter in full flower. Mr. M'Nab 

 concluded the present part of his journal with an account of some 

 large trees of the hemlock spruce, Abies canadensis, being the first of 

 this tree which the party had observed in natural situations : — the 

 largest specimens were about 10 feet in circumference, and 80 feet in 

 height. 



The Honorable G. C. Cunningham, Mauritius, and F. S. Cordier,

BOTANICAL SOCIETY OF LONDON. 



July 5, 1844. — Dr. Francis Bossy in the chair. 



Specimens of the following plants were exhibited, sent to the Soci- 

 ety by Mr. Hewett Watson. 



Carex elongata {Liuii.), found abundantly in Weybridge marshes. 

 This locality is interesting to the metropolitan botanist ; the nearest 

 habitat previously on record being in the county of Salop. 



A pubescent-flowered vaiiety of Bromus commutatus {Schrad.), 

 found plentifully, along with the more abundant glabrous form, in a 

 meadow by the river Mole, between Esher and West Moulsey, Surrey. 

 This variety affords another instance to prove the little importance 

 which can be given to the character of smooth or downy flowers, as a 

 specific distinction in this genus. It will form an addition to the 

 ' London Catalogue of British Plants ' (b. iJuhens), to be entered un- 

 der " Bromus (1355) commutatus." 



A specimen of Lolium multiflorum, the root of which was dug up, 

 when in flower, in a sown field last year, and the plant is now copi- 

 ously flowering in Mr. Watson's garden ; thus proving its perennial 

 existence, although the alleged annual root of L. multiflorum has been 

 considered the best distinction between this supposed species and L. 

 perenne. The other alleged differences are equally invalid. 



Garden specimens of Festuca pratensis {Huds.) and F. arundina- 

 cea {Schreb.), to show the strongly marked differences between them ; 

 the latter being three times the size, extremely harsh to the touch, and 

 very dissimilar in its flowers and mode of inflorescence. In F. pra-
