The Mountain Trefoil (Page 21) is a stiff-looking plant, with 
pale pink flowers. It is common in mountain pastures. The 
leaflets are hairy underneath, and the flower stalk becomes deflected 
when the flowers fade. 
The Brown Trefoil (Page a2) is common and distinctive. The 
globular flower beads are at first of a golden yellow colour, and are 
held erect on the long flower stalks. Hut laler on as they fade, 
the flower heads hang down and become a glossy brown. The 
corolla, now brown and dry, remains In this way attached to the 
seeds, and is of considerable importance in assisting their distribu- 
tion by the wind. The leaves are long-stalked, and the three leaflets 
have finely serrated margins. 
The Alpine Rose ( Rosa A Ip in a, Page *3) must not be con- 
fused with the Alpenrose which is seen on pages 38 and 39 of the 
First Seiies. The names are liable to lead to confusion. The 
Alpine Rose is a shrub bearing rose-red flowers, with a faint 
fragrant scent. The leaves have 7 to 11 leaflets and the flowering 
branches are entirely without spines. Indeed it is unusual to find 
spines on any but the very youngest shoots. There are several 
sub-species. 
Fleischer’s Willow-Herb is seen on Page 24. It grows in 
dried-up torrent beds in the high Alps but is rather local. Very 
closely resembling it is a commoner species Epiloiium rosmarini- 
folium. The latter is usually a bigger plant « it h more closely packed 
leaves and its style is about as long as the stamens, whereas the 
style of Fleischer's Willow Heib is much shorter. 
The Perennial Knawel (Page 25) is fairly common in dry places 
but is not exclusively Alpine. The broad white margin of the green 
calyx is characteristic. 
Two species of Stonecrop are photographed. The Annual 
Stonecrop (Page 26) is a fairly common plant with yellow flowers. 
The whole plant is without hairs and the leaves are fleshy and 
cylindrical. The individual flowers have very short stalks The 
Thick-leaved Stonecrop (Page 27) is very common. The thick 
succulent leaves are in pairs opposite *ne another and are often 
spotted with red, and the flowers are white and tend to hang down. 
Three more species of Saxifrage are illustrated in this volume. 
They should be carefully compared with those on pages 24 to 2S of 
the First Series. The Moss-like Saxifrage (Page 28) is really a 
Cushion plant growing in inoss-like tufts in the fissures of rocks in 
high Alpine regions. The Rough Saxifrage ( Page 27— First Series) 
very closely resembles it, for both have yellowish white flowers. 
Apart from technical details the smaller and more closely packed 
leaves of the Moss-like Saxifrage are perhaps the best guides 
to its identification. The general habits of the two plants will be 
easily seen by a comparison of the two photos. 
The Wedge-leaved Saxifrage (Page 29) is rather rare. It 
grows in moist places on the Alps. The wedge-shaped leaves are 
smooth and leathery, and have a thickened margin. The flower 
stem is long and branched, and the white flowers have almost 
invariably a yellow spot in the centre of each petal.
