244 Localities of British Plants,

Cwn and Llyn y Cw#z. In most botanical books, the latter 

 name is used in mistake for the former. Any stranger, who 

 may ask his guide for Llyn y Cwm, will be taken to Llyn 

 Cwm Ffinnon, near the head of the Llanberis Pass ; a station 

 not celebrated for any rare plants. 



As some doubt has been expressed of the true structure of 

 the seed of Subularia aquatica, I examined it on the 

 spot, and made the drawing annexed, which is con- 

 firmatory of Dr. Hooker's view of the cotyledons 

 being incumbent. (Fig. 33., in which the seed of 

 Subularia aquatica, without its external coats, is 

 represented. 



Helidnthemum guttdtum. On the right-hand side of a little 

 hollow running up into Holyhead Mountain, at about 50 yards 

 before reaching the descent to the South Stach Lighthouse, 

 Anglesea. Aug. 6. 



ILldtine hexdndra. In the stream flowing from Llyn Mea- 

 log, Anglesea, just above the mill. Aug. 3. Just below 

 the same mill, 



Callitriche autumndlis occurs in plenty. This is the only 

 recorded Welsh station for C. autumnalis. The plant com- 

 monly taken for it, in Caernarvonshire, is C. pedunculdta, but 

 having its fruit usually sessile. It may be easily distinguished 

 from C. verna by not having any bractese at the base of its 

 fruit stalk. 



Medicdgo maculdta and denticuldta. These two plants I 

 noticed in the plantation opposite to the terrace at Southend, 

 Essex. June 20. The latter occurs, together with 



Trifblium stelldtum andVicia liitea, on a shingle bank close 

 to the river at Shoreham, Sussex, on the opposite side from 

 the town. June 16. 



la&thyrus hirsiitus. Amongst bushes, just below Hadleigh 

 Castle, Essex. June 22. 



lubtus major. The specific character of this plant appears 

 to be: — heads depressed, many-flowered; stems tubular; claw 

 of the standard linear; apex of the flower-buds stellate. 

 Much of the confusion attending this plant has been caused 

 by supposing that it must always be large, hairy, and upright. 

 I have seen it nearly quite glabrous, and as small as L. cor- 

 niculatus, but still retaining its characters in a marked man- 

 ner. Near Holyhead, Anglesea, Aug. 6., I found 



L. corniculdtus var. crassifblius. This is a curious form of 

 the common plant, growing in loose sand, and agreeing well 

 with De Candolle's character : " Pilosus, foliolis ovatis sub- 

 carnosis, caulibus foliosis prostratis." 



Viola flavtcornis. On the sands near Llyn Coron, AngTe-
