1. Crepis virens, L. This is the Crepis tectorum of British au- 
thors, which must henceforth be removed from our Flora, 
C. virens has the leaves even at the margin, the achenia smooth, 
and shorter than the pappus. C. tectorwm has the leaves revolute at 
the edges, and the achenia scabrous, equalling the pappusin length. 
2. Habenaria chlorantha, and bifolia. The former is the Orchis 
bifolia of Fl. Brit, and Engl. Bot., and the latter is the difolia of 
Linnzus, as is proved by the specimen in his Herbarium, and is 
identical also with the Platanthera brachyglossa of Reichenbach. 
Among the additions to the British Flora we may reckon the 
following: Ist, /Zerniaria ciliata, a species hitherto confounded 
with glabra; from which it is principally distinguished by its ovate 
ciliated leaves, The Cornish habitat for glabra belongs to thisspecies. 
2ndly, Polyzonum maritimum, L., found by Mr. Borrer on_ the 
sandy shore near Muddiford. 3rdly, P. Razz, the marinum of Ray’s 
Synopsis, and the aviculare e of Smith. 4thly, P.dumetorum, L., 
an interesting addition discovered by Mr. Hankey in a wood near 
Wimbledon. 5thly, Luphorbia corallioides, L., found at Slinfold, 
Sussex, and perhaps scarcely to be reckoned indigenous. It is the 
pilosa of the Ist edit. of Hooker's Brit. Flora. 6thly, Erica 
Mackait, a species discovered on Craigha Moira, Cunnemara. In 
its essential characters it approaches to E. Tetralix; but in habit it 
resembles E. ciliaris.

Some account of a species of Agave introduced accidentally into 
the Deccan; by Lieut.-Col. Sykes, F.R.S. &c.,—was read. 
A number of young plants of this species came up accidentally 
in the garden of the collector at Poonah, in a border that had been 
appropriated the year before to a collection of bulbous roots that 
had been obtained from the Cape of Good Hope. One of the 
lants flowered in the fifth year after their first appearance. The 
height of the flower-stem was 25 feet. Although the fowers were 
apparently perfect, no seeds were produced. After the flowers had 
fallen, a multitude of small bulbs were produced on the branches. 
The species proves to be identical with the Agave cubensis, a plant 
discovered by Jacquin in the island of Cuba. It belongs to Ven- 
tenat’s Fourcroya, a group of species distinguished from the normal 
Agaves by their dilated filaments, and by the thickened base of the 
style.

November 10, 1835.—At the request of the Chairman, Mr. Gould 
exhibited a specimen of the true Lanner Hawk, Falco Lanarius, Linn., 
and entered into some details with respect to its distinguishing pe- 
culiarities. Its real characters, he stated, have hitherto been so im- 
perfectly understood as to have led to very general doubts as to its 
existence as a distinct species. 
Mr. Gould also exhibited specimens of two species of Pheasant,
