 The plant is hairy and bluish-green. The root- 

 stock is woody, flattened, the branches leafy above. 

 The leaves are downy both sides, trifoliate, the 

 leaflets are wedge-shaped, with 3 teeth at the

Alpine Lady's Mantle (Alchemilla alpina, L.). 

 The habitat of this species is mountain streams 

 and rocks. The habit is more or less the rosette 

 habit. The plant is clothed with soft silky hairs, 

 except the upper surface of the leaves. The root- 

 stock is slender and branched. The branches are 

 ascending above, usually simple, the stem slender, 

 ascending. The leaves are finger-shaped, toothed, 

 with 5-7 lobes, separate to the base, oblong, blunt, 

 on slender stalks, the upper stalkless, rounded to 

 kidney-shaped. The leaflets are narrow, oblong 

 to egg-shaped, suddenly long and narrowly 

 pointed, sharply toothed at the apex. The stipules 

 are united at the base, cleft. The flowers are 

 yellowish-green, on short hairy stalks, in inter- 



rupted spikes or small lateral and terminal 

 corymbs. The achenes are slightly glandular. 

 The plant is 3-9 in. long, flowering from June to 

 August, and is a herbaceous perennial. 



Pyrus minima, Ley. The habitat of this plant 

 is limestone cliffs. It is a native, and abundant 

 where it occurs, growing up to 1600 ft. Seedlings 

 are frequently produced. It is a small, spreading 

 tree or shrub, with many slender branches. The 

 leaves are linear, oblong, divided slightly to the 

 base, with 3-4 pairs of lobes, deepest at the 

 middle or upper part, the lowest one-third or one- 

 fourth not lobed. The lateral veins are 5-7, form- 

 ing an acute angle with the midrib, prominent 

 below and grooved above, the underside having 

 a grey felt. The flowers are in loose corymbs, 

 not flat-topped, the petals round, cream-coloured, 

 the calyx erect and prominent, persistent till the 

 fruit is ripe. The fruit is small, globose, bright 

 coral-red, bitter, ripening in August or September.

 glens. It is a rare species. The plant has the 

 tree habit. The leaves are oblong, toothed, pinnate 

 below, with 1-4 pairs of free leaflets, the base 

 running down the stem, and 1-2 pairs of free lobes, 

 the leaflets and lobes oblong or narrowly elliptic. 

 The underside is grey-felted. The flowers are 

 white, in a corymb. The plant is regarded as a

 tall, flowering in June and July, and is a deciduous 

 tree.

 habit. The stems are erect, with downy branch- 

 lets. The leaves are round below, broadly elliptic 

 to oblong, ovate, densely downy below, entire,
