 crowded on the flowering- shoots, bent back, green, 

 convex both sides, spurred below, acute, spread- 

 ing, numerous. The flowers are yellow in nearly 

 flat-topped cymes, the outer branches bent back 

 or spreading', stalked. The sepals are ovate, 

 acute, not gibbous below, the petals lance-shaped, 

 blunt. The anther-stalks and lateral edges of the 

 carpels have glandular hairs. The plant is 6-1 2 in. 

 high, flowering in June and July, and is a herb- 

 aceous perennial. 



Rock Stone-crop (Sedum rupeslre, L.). The 

 habitat of this species is limestone rocks (hence 

 rupestre). The plant has the rosette habit. The 

 barren stems are short, with densely overlapping, 

 appressed, bluish -green leaves. The plant is 

 smooth. The stems are stout, loosely tufted, 

 green or pink-tinged. The flowering stems have 

 erect, scattered leaves. The leaves are linear, 

 lance-shaped, flat, spurred below. The flowers 

 are yellow, in flat-topped scorpioid, corymb-like 

 cymes. The sepals are oblong, blunt, elliptic. 

 The petals are lance-shaped, acute. The anthers 

 are yellow, the stalks smooth, as are the ovaries. 

 The plant is 6-10 in. high, flowering in June and 

 July, and is a herbaceous perennial. 



Small Welsh Stone-crop (Sedum forsterianum, 

 Sm.). The habitat of this species is wet rocks, 

 chiefly in the W. of England. The plant has the 

 rosette habit. It is more slender than 5. rupestre, 

 of which it has been regarded as a subspecies. 

 The barren stems are short, erect, with crowded 

 leaves, which are lance-shaped, bright-, not bluish- 

 green, spurred below, flattened, forming small 

 rose-like tufts. The flowers are yellow, in com- 

 pact, round-topped cymes. The sepals are ovate, 

 the petals lance-shaped. The anther-stalks and 

 ovaries are smooth. The plant is 6-10 in. high, 

 flowering in June and July, and is a herbaceous 

 perennial. 



ORDER ONAGRACE^E 



Mountain or Chickweed Willow-herb (Epilob- 

 turn alsincefo Hum, Vill.). The habitat of this 

 species is spongy banks of rills, alpine and sub- 

 alpine districts. The plant is almost devoid of 

 hair. The root is creeping. The stems are tufted, 

 ascending-, with 2-4 lines of down. There are 

 yellow summer stolons, which are subterranean, 

 slender, bearing- rather round, distant scales, and 

 scaly buds in autumn. The stems are erect, wavy, 

 simple, more or less succulent (hence alsincefolium), 

 rooting below. The leaves are opposite as a 

 rule, ovate to narrow-pointed, with bent-back 

 teeth, shortly-stalked, smooth, shining, rather 

 membranous. The flowers are few, large, purple 

 or rose-colour. The buds are bluish, nodding. 

 The sepals are linear to oblong. The capsule is 

 erect, long, long-stalked, nearly smooth. The 

 seeds are narrow, club-shaped. The plant is 

 4-12 in. in height. It flowers in July, and is a 

 herbaceous perennial. 



Alpine Willow-herb (Epilobium alpinum, Huds. 

 = anagallidifolium, Lam.). The habitat of this 

 Willow-herb is mountain rills of the higher moun-

tains. The plant has the rosette habit, and is 

 prostrate below. The plant is small, somewhat 

 downy. The summer stolons are subterranean, 

 and form a rosette. The barren stems are short, 

 with close upper leaves; the flowering stems are 

 erect, from a short rooting base, with oval or 

 oblong leaves, blunt, narrow below, not long- 

 pointed. The stem has raised lines of down, 

 and is ascending, slender, simple, curved. The 

 leaves are few, pale-green, short-stalked, the 

 upper lance - shaped, elliptic, blunt, entire or 

 toothed, red-tinted, opposite. The buds are blunt, 

 nodding. The flowers are drooping, pale rose- 

 purple, the sepals linear to lance-shaped, acute. 

 The capsule is nearly hairless, the seeds narrow 

 to inversely egg-shaped, pointed below, with a 

 blunt point. The plant is 2-9 in. high, flowering 

 in July, and is a herbaceous perennial. 



ORDER UMBELLIFER^ 



Rigid Hare's Ear or Small Hare's Ear (Bu- 

 pleurum opacum, Lange = Bupleurum arista/urn, 

 Bartl.). The habitat of this plant is sandy places 

 and rocks. The habit is rigid, erect, with simple 

 or forked stems, which are solid, the leaves sword- 

 shaped, linear, lance-shaped, finely furrowed. The 

 lower leaves may be stalked. The flowers are 

 yellow, the oblong bracts bearing an awn. The 

 plant is 2-8 in. in height, flowering in June and 

 July, and is an annual. 



Honewort (Trinia vulgaris, D.C. = Apinella 

 glauca, Camel = Trinia glauca, Dum. = 7. 

 glaberrima, Hoffm.). The habitat of this plant 

 is dry limestone rocks or hills. The plant is 

 bluish-green. The rootstock is spindle-shaped, 

 woody, crowned with remains of last year's leaves 

 and leaf-stalks. The stems are erect, branched, 

 solid, stout, deeply - grooved, with spreading 

 branches. The leaves are tripinnate, the leaflets 

 linear and slender, spreading, bluish-green. The 

 segments and leaf-stalk are very slender. The 

 plant is dioecious. The flowers are white, minute. 

 The umbels of the male flowers are flattened, 

 those of the female irregular, with longer rays. 

 The bracts are 3-cleft, solitary or absent. The 

 bracteoles are linear, 2-3. The fruit is ovoid, 

 with blunt ridges. The carpophore has flat seg- 

 ments. The styles are slender. The plant is 

 3-6 in. high, flowering in May and June, and is 

 a herbaceous perennial.

English Wall Bedstraw (Galium anglictim, 

 Huds.). The habitat of this plant is walls and 

 dry sandy places. The habit is prostrate. The 

 stems are spreading, branched, slender, brittle. 

 There are no barren shoots. The leaves are 6 

 in a whorl, or the lower 4 in a whorl, narrow, 

 linear, blunt -pointed, bent-back at length, the 

 margins rough, with forwardly-directed prickles. 

 The flowers are few, greenish -white, in small, 

 forked, axillary and terminal cymes, panicled,
