(This species is also viscid, “ though less so at an advanced age, and in cold 
weather.” E. Bot. The most obvious distinction seems to be the trailing, 
or upright stems. E.) Whole plant rough with hairs. Calyx leaves mem¬ 
branous at the edge. (A larger, coarser, and spreading plant, with longer 
and narrower leaves and flowers , shorter than their foot-stalks in general, 
and especially in fruit. Hook. The stronger the plant the smaller the 
petals and vice versa , hence by the size of its petals alone it is sufficiently 
distinguished on heaths, where it frequently grows about two inches 
' high, and is often taken for C. semidecandrum. FI. Lond. When grow¬ 
ing among other plants, upright. Whole herb of a darker green than the 
preceding. E.) When growing in bogs the leaves are sometimes as 
convex as an egg cut through lengthwise. Aik.

Whole plant, except the petals and capsules, covered with long, soft, 
shining hairs. Lower leaves oval; upper oval-spear-shaped, opposite. 
Branches, terminated by one or two flowers. Flowers large, on separate 
fruit-stalks, each furnished with two opposite spear-shaped floral-leaves. 
Capsule when ripe lengthened out into a straight horn. Woodw. 
We have two varieties of this, one with the leaves quite smooth and almost 
glossy; the other with woolly leaves ; but they are clearly one species. 
What can be the cause of the smoothness of the one, growing as they do, 
intermixed ? Flowers generally one, and sometimes two, but in the 
Hutch gardens, several on a stem. Linn. FI. Lapp. Some plants green, 
and others hoary. Doubted whether not two distinct species. Ray. 
Hairs on the fruit-stalks transparent, jointed, the knots somewhat opake. 
Griff. From two to four inches high, branched and creeping below. 
Flowers white, (petals obcordate. E.) 
Alpine Mouse-ear Chickweed. Mountains and sides of rills, as on 
Snowdon, on the north side of y Wyddfa and Clogwyn du ’r Arddu near 
Llanberris. Top of Clogwyn y Garnedd, very near to plants of C. lati- 
folium. Mr. Griffith. (On Ben Lawers and Lomond. On Helvellyn,

C. latifo'lium. (Leaves elliptical, rough, with short, bristly hairs : 
flower-stalks terminal, simple, mostly solitary: capsule oval.

(The stems form tufts, but are shorter and more thickly set with leaves than 
in C. alpinum ; leaves broader and more obtuse, clothed ( constantly, as 
far as we have observed) with numerous short rigid spreading bristly 
hairs, various in position and direction, making a harsh kind of covering, 
quite different from the silky hairs of C. alpinum,. They are also in gene¬ 
ral more thickly jointed. Th e flower-stalks are terminal, mostly solitary, 
simple, often as long as the whole stem, clothed with glandular spreading 
hairs, and frequently destitute of bractese. The flowci's differ but little
