 style is short. The plant is 4-12 in. high, flower- 

 ing from June to August, and is a perennial or 

 biennial. 



Cochlearia micacea, E.S.M. The habitat of this 

 species is high Scottish mountains. The plant is

 being a small, prostrate plant. The leaves are 

 small. The pod is narrower, 1^-3 times as long 

 as broad. The plant is 2-4 in. high, flowering 

 from June to August, and is a herbaceous bien- 

 nial.

 places. The plant has the rosette habit. The 

 stems are numerous, or solitary, slender, ascend- 

 ing, with one or two small leaves. The leaves 

 are radical, numerous, flat, divided nearly to the 

 base, the lobes larger upwards, or rounded, spoon- 

 shaped, entire. The flowers are white, in a 

 corymb, then a raceme, the 2 outer petals twice 

 as long as the rest, unequal. The stamens bear 

 scales. The style is very short. The pods are 

 notched, winged, on short, slender, spreading 

 stalks. The plant is 5-12 in. high, flowering in 

 June and July, and is a herbaceous annual. 



ORDER RESEDACE^K 



Wild Mignonette (Reseda lutea, L.). The 

 habitat of this species is chalky and sandy fields, 

 limestone tracts, waste places. The habit is

 The leaves are divided nearly to the base, 2-3- 

 lobed, the lobes few, distant, blunt, linear. The 

 flowers are in a dense raceme, conical, pale-yellow. 

 The sepals and petals are unequal. The 5 sepals 

 are linear, the upper smaller. The 6 petals are 

 unequal. The 3 upper petals have wing-like lobes, 

 the claw is 2-lobed, the limb 3-lobed, the lateral 

 2-lobed with i wing, the lower nearly entire, pro- 

 tecting the honey. There are 3 stigmas. The 

 capsule is oblong, wrinkled, 3-toothed. The seeds

ORDER CISTACE/E 



White Rock Rose (Helianthemum polifolium, 

 Mill.). The habitat of this species is stony places, 

 slopes near the base of hills. The habit is trail- 

 ing, prostrate, shrubby. The stem is branched, 

 prostrate, hoary, downy both sides, with stipules. 

 The leaves have bent or rolled-back margins, and 

 are opposite, with stipules, egg-shaped to oblong, 

 linear. The flowers are white, in racemes, with 

 bracts on the stalks. The sepals are downy, the 

 inner blunt. The style is bent below, longer than 



the ovary. The plant is 8-10 in. high, flowering 

 from May to July, and is a perennial under- 

 shrub. 



Spotted Rock Rose (Helianthemum guttatum, 

 Mill.). The habitat of this plant is stony, heathy 

 places. The habit is erect. The stem is hoary 

 or downy, simple or forked, and branched from 

 the base, without bracts. The leaves are oblong 

 to lance-shaped, linear, the lower leaves are 

 opposite, the upper alternate, with stipules. The 

 flowers are yellow, with deep-red or chocolate 

 spots below (hence guttatum). The petals are 

 wedge-shaped. The fruit-stalks are spreading, 

 without bracts. The stigma is nearly stalkless. 

 The plant is 4-12 in. high, flowering between May 

 and August, and is a herbaceous perennial. 



Hoary Rock Rose (Hclianthem-um canuNt, 

 Baumg. = H. marifolium, Mill.). The habitat of 

 this species is dry banks, rocks, limestone rocks. 

 The habit is prostrate, shrubby. The stem is woody, 

 much-branched, hoary (hence canurn), with stipules. 

 The leaves are hoary both sides, or hairy above, 

 egg-shaped, oblong, stalked, flat, opposite. The 

 flower-stalks bear bracts. The flowers are few, 

 small, yellow, in terminal racemes with bracts. 

 The style is twisted below, bent back at the tip, 

 bent in, longer than the stigma. The anthers are 

 notched both ends. The plant is 6-8 in. long, 

 flowering from May to July, and is a perennial 

 shrub. 



ORDER YIOLACE/E 



Viola calcarea, Greg. The habitat of this violet 

 is calcareous ground. The plant was formerly 

 regarded as a variety of Viola hirta. It is small, 

 glabrous, without stolons. The rootstock is 

 branched, thick, woody. The leaves are small, 

 egg-shaped, oblong, heart-shaped. The flower- 

 stalks are longer than the leaves. The flowers are 

 very small, violet or mauve, the throat the same. 

 The petals are narrow, the 4 upper forming a St. 

 Andrew's cross, the sepals oblong to egg-shaped. 

 The spur is very short, straight, conical. The 

 capsule is small, roundish, depressed. It is a her- 

 baceous perennial plant, flowering in April and 

 May. 



Sand Violet (Viola arenaria, D.C. = rupestris, 

 Schmidt). The habitat of this species is elevated 

 calcareous pastures. The habit is tufted. The 

 rootstock is thick, woodv, brown, clothed with

 shaped, with a short point, thick, dotted, nearly 

 entire. The flowers are large, blue, the anterior 

 petal long, narrow, notched, with a blunt point. 

 The spur is short, thick, furrowed. The sepals 

 are hardly acute. The bracts are slender, entire,

 as the anther, which has a blunt scale. The cap- 

 sule is downy. The plant is 1-3 in. high, flowering 

 in May, and is a herbaceous perennial.
