at all reflexed. This form is about midway between C. nutans and 
the Continental C. acanthoides, differing from C. nutans about as much 
the latter does from C. crispus. 
Cardans crispus, L. Mr. Briggs sends a specimen from Yealmpton, 
with the remark — " very local and rare near Plymouth." 
" Carduus pseudo-Forsleri" With specimens collected at Esher, 
Surrey, and thus named, Mr. Watson writes — " This luxuriant form of 
C. pratensis has been often misnamed C. Forstei'i {e.g. by Sir W. J. 
Hooker, Mr. Mill, etc.)." It does not differ from the usual C. pratensis, 
except in size. 
Cuscuta Trifolii, Bab. Mr. Briggs sends this from near Plymouth. 
It is not included in the Devon list in the * Cybele.' One specimen is 
parasitical on Tri folium hybridum. 
Mentha Pulegium, L. Mount Edgecumbe, Devon (Mr. Briggs). 
New to the Devon flora. 
Galeopsis Ladanum, L., var. canescens. Mr. Briggs sends from the 
neighbourhood of Plymouth a Galeopsis which differs from the common 
British form of G. Ladanum (G. angustifolia, Ehrh.), by having the 
calyx, and in a less degree the stem and upper leaves, densely clothed 
with firm, ererto-patent, white woolly hairs. In this form the flower 
measures about 9 lines from the base of the calyx to the tip of the co- 
rolla, the calyx being not quite half of this, so that the corolla-tube 
considerably exceeds it. When the plant is in flower, the longest 
teeth are not more than ± inch long, about half of this being a mere 
cartilaginous awn. This is evidently the G. canescens of Boreau, and 
comes very near our specimens of O. arvaiica, Jordan. 
Mr. Syme sends the same plant from Peg well, Kent, and the Rev. 
Mr. Newbould believes he has observed it in some parts of Cambridge- 
shire. It is probably a not uncommon plant. 
Stachys ambigua, Sm. Mr. Syme contributes a specimen thus 
named, from " between Weymouth and Portland, near the bridge, 
Dorset." Examples named Stachys palustri-sylmtica, are sent from 
Devon (Mr. Briggs), Warwick (Mr. Bromwich), and Manchester (Dr. 
Windsor). These last-mentioned plants agree all with one another, 
and differ from Mr. Syme's in the form of the leaves. The leaves of 
the Dorset plant are oval or oblong, acute, slightly cordate at the base, 
coarsely and rather shallowly crenate-serrate. In S. palustri-sylvatica 
the leaves are oblong-ovate, ovate-lanceolate, or oblong-lanceolate,
