HEATHS AND MOORS 



157 



half the diameter of the pod, in 2 rows, spreading, 

 hooked. The seeds are narrowly kidney-shaped. 

 The plant is 6 in. to 2 ft. high, flowering from 

 May to August, and is a herbaceous annual. 



Spotted Bur Medick (Medicago arabica, Huds.). 

 The habitat of this plant is either by the way- 

 side, on hedgebanks, or in pastures, or waste 

 ground, cornfields. It is more common in South 

 and South-east England, and a casual elsewhere. 

 The habit is prostrate, the numerous smooth stems 

 bearing inversely heart-shaped leaflets, with a 

 purple spot (hence another name, maculata, Sibth.) 

 in the centre. The flower-staiks bear 1-4 yellow 

 flowers, and the nearly round pods with 3-5 coils, 

 many-seeded, bear 4 ridges and a central furrow 

 on the broad edges. The plant is 5-8 in. in height. 

 It flowers between May and August, and is an 

 annual. 



Little Bur Medick (Medicago minima, Wesr.). 

 The habitat of this plant is sandy fields, chiefly 

 in the south-east, but it is a rare plant. The plant 

 is prostrate, rigid, downy, with numerous stems. 

 The flowers are yellow. The pods are nearly 

 round, and differ from those of the rest of the 

 Medicks in being smooth, with a thin edge, coiled 

 four times. The flowers are very small, being not 

 more than in. across. The plant is 6-10 in. in 

 length. Flowers are found between May and July, 

 and like the others the plant is annual. 



Slender Clover (Trifolium filiforme, L.). The 

 habitat of this plant is dry places, often near the 

 sea, heaths, &c. The habit is prostrate. The 

 plant is sparingly hairy. The stem is very slender 

 (hence filiforme\ The leaves have lobes each side 

 of a common stalk in threes, or finger-like. The 

 leaflets are inversely heart-shaped or egg-shaped, 

 toothed at the tip, stalkless. The stipules are 

 egg-shaped above, acute. The flowers are dark- 

 yellow, few (2-7), in a loose raceme, turned-back, 

 axillary. The flower-stalk is thread-like, the ulti- 

 mate stalks as long as the calyx, spreading, 

 or turned-back. The standard is keeled, folded 

 over, the pod deeply notched. The pod and calyx 

 are as in the last. The plant is 2-9 in. long, 

 flowering in June and July, and is a herbaceous 

 annual. 



ORDER ROSACES 



Rubus Rogersii, Linton. The habitat of this 

 plant is heaths, moors, in sunny places. The habit 

 is shrub-like. The stems are suberect, the leaves 

 rather small, 6-lobed, finely, closely, and evenly 

 toothed. The leaflets are greyish - green, very 

 pale, felted beneath, the terminal leaflets egg- 

 shaped, heart-shaped, with a long point. The 

 panicle bears crowded, sickle-like prickles, stout 

 at the base. The style and stamens are of about 

 the same length. The fruiting sepals are loosely 

 turned-back. 



Rubus integribasis, P. F. Mueller. The habitat 

 of this species is sandy commons and stream 

 borders. The habit is shrub-like. The stem is 

 suberect, slender, high-arching. The leaves are 

 only thinly hairy beneath. The leaflets are opaque 

 above, the terminal leaflet inversely egg-shaped, 



or oval, with a blunt point. The panicle is loose, 

 racemose, very narrow, with weak, declining 

 prickles. The sepals are hairy and grey, or grey- 

 ish-green externally. The plant flowers early. 



Creeping Tormentilla (Potentilla procumbens, 

 Sibth.). The habitat of this species is woods and 

 heaths, hedgebanks. The habit is trailing or 

 prostrate, then ascending, rooting at the joints. 

 The leaflets are inversely ovate to wedge-shaped, 

 the stem-leaves with 3-5 leaflets, sometimes 

 stalked, with the stipules entire or divided into 

 3 lobes. The flowers are large, yellow, few or 

 solitary, f in. across. There are 4 or 5 petals. 

 The achenes are netted. The plant is 6-15 in. 

 long, and is in flower between June and September. 

 It is a herbaceous perennial. 



Silvery Cinquefoil (Potentilla argent 'ea, L.). 

 The habitat of this species is dry gravelly pastures 

 and roadsides. The habit is prostrate and ascend- 

 ing. The plant is covered with closely pressed 

 woolly, silvery, hairs (hence argentea). The root- 

 stock is short and woody. The stems are slender, 

 branched, leafy. The leaves are 5-lobed, finger- 

 like, stalked, the upper nearly stalkless. The 

 leaflets are narrow, wedge-shaped, inversely egg- 

 shaped, cut, toothed, white and downy below, 

 with a rolled-back or bent-back margin, half- 

 divided nearly to the base. The flowers are 

 small, yellow, in more or less of a corymb, ter- 

 minal. The flowering stems are annual at the 

 end of the branches of the perennial rootstock. 

 The receptacle is hairy. The achenes are smooth 

 and hairless. The plant is 4-18 in. long, flower- 

 ing from June to August, and is a herbaceous 

 perennial. 



Parsley Piert (Alchemilla arvensis, Scop.). 

 The habitat of this plant is fields, dry pastures, 

 waste places, cornfields. The habit is prostrate, 

 or ascending, with hairy, branched stems, and 

 leaves wedge-shaped below, or fan-shaped, divided 

 into three nearly to the base. The stipules or leaf- 

 like organs are palmate, with lobes spreading from 

 a common point. The yellowish -green flowers 

 are in the axils and stalkless, and are hidden by 

 the stipules. The calyx is 4-lobed. There are 

 1-3 achenes. The plant is small, 2-5 in. in height, 

 flowering in May up till August, and is a her- 

 baceous annual. 



ORDER CRASSULACE^E 



Mossy Tillaea (Tillcea muscosa, L.). The habi- 

 tat of this plant is barren sandy heaths in the south 

 and east. The plant has the cushion habit, and 

 is prostrate, then ascending, growing in tufts, 

 and is of a red colour. The stems are branched, 

 smooth, with slender branches, leafy, and all bear 

 flowers. The leaves are thick, oblong, opposite, 

 hollow above, blunt or with a short point, united 

 below. The flowers are white with red tips, ses- 

 sile or stalkless, in the axils, 3-cleft. The parts 

 of the flower are rarely in fours. The sepals are 

 ovate, with a long, narrow point, acute, and 

 green. The petals are small, awl-like. There 

 are no scales. The follicle is constricted, and
