BRITISH FLORA 



ORDER SCROPHULARIACE^; 



Mudwort (Limosella aquatica, L.). The habi- 

 tat of this plant is the margins of ponds, muddy 

 places where water has lain. The habit is the 

 rosette habit. The rootstock is slender, creeping, 

 rooting. The plant is very small. There is no 

 stem, except the underground or creeping stolons. 

 The leaves are narrow, oblong to lance-shaped, 

 or spoon-shaped, tufted, long-stalked. The flowers 

 are small, white, or rose-coloured, on axillary 

 stalks, not so long as the leaves, or leaf-stalks, 

 bent back in fruit. The capsule is ovoid and very 

 small. The plant is 1-4 in. in height, flowering 

 between July and September, and is a herbaceous 

 annual. 



Water Speedwell ( Veronica Anagallis-aquatica, 

 L.). The habitat of this plant is watery places. 

 The plant is prostrate then ascending in habit. The 

 plant is stoloniferous, devoid of hairs, erect, stout, 

 hollow, succulent. The stem is simple or bears 

 a few branches. The leaves are stalkless, half- 

 clasping, ovate, oblong to lance-shaped, coarsely 

 toothed, with small teeth, and auricled. The 

 flowers are pale-blue, in slender, sometimes glan- 

 dular, ascending, opposite racemes, which 

 lengthen in fruit. There are lance-shaped bracts, 

 as long as the ultimate flower-stalks. The sepals 

 are ovate to lance-shaped, more or less acute, 

 smooth or glandular. The fruit-stalks are spread- 

 ing. The capsule is elliptical, oval, notched, 

 turgid, not so long as the sepals. There is a 

 medium-sized style. The seeds are small, bicon- 

 vex. The plant is 1-3 ft. high, flowering in July 

 and August, and is a herbaceous perennial. 



ORDER LENTIBULARIACE^E 



Utricularia neglecta, Lehm. (= U. major, 

 Schmidt). The habitat of this plant is pools in 

 heathy places. Similar to U. vulgaris, this species 

 was formerly regarded as a sub-species. There is 

 a slender stem and scape. The leaves are not so 

 large as in the last, more distant. The stems are 

 slender, or hairlike. The leaves are nearly round, 

 with awl-like, entire segments, pinnate, and much- 

 divided, fringed with hairs in places. On the 

 leaves are the small bladders, which are shortly- 

 stalked. The scape is very slender. The corolla 

 is pale-yellow, borne on slender stalks, 4-5 times 

 as long as the lance-shaped bract, with a spur 

 which is conical, directed upwards, and project- 

 ing, ovate to oblong, blunt or notched, not closely 

 pressed to the upper lip. The upper lip is 2-3 

 times as long as the palate. The lower lip has a 

 broad, flat, spreading margin. The flower-stalks 

 are ascending in fruit. The plant is 6-8 in. in 

 height, flowering between June and August, and 

 is a herbaceous perennial. 



Smaller Bladderwort (Utricularia minor, L. = 

 U. ochroleuca, R. Hartm.). The habitat of this 

 plant is pools, ditches, pits. The habit is as in 

 the last, and U. vulgaris. The stems are thread- 

 like. The leaves are regularly forked in two 

 parts, much-divided, loose, broad, round, with 



awl-like, entire segments, not fringed with hairs. 

 The pitchers have slender stalks. The scapes 

 bear 2-6 small flowers, pale-yellow. The flower- 

 stalks are 2-3 times as long as the calyx, bent 

 down in fruit. The upper lip of the corolla is as 

 long as the small palate, the lower broadly ovate, 

 with a flat spreading margin. The spur is very 

 short, small, and blunt. The sepals are round, 

 long-pointed. The anthers are free. The plant 

 is 3-10 in. in height, flowering from June to Sep- 

 tember, and is a herbaceous perennial. 



Utricularia intermedia, Hayne. The habitat of 

 this plant is pools, ditches, bogs, pits. The habit 

 is as in the last. The stem is slender. The leaves 

 are in 2 rows, close, repeatedly forked, much- 

 divided, 3-partite, broad, round, with awl-like, 

 linear segments, with a fringe of distant hairs. 

 The pitchers are on slender stalks, on leafless 

 branches. The scape is stout. The flower-stalks 

 are as long as the calyx. The flowers are pale- 

 yellow. The upper lip is longer by twice than the 

 swollen palate. The lower lip has a broad and 

 flat, spreading margin. The spur is closely pressed 

 to the lower lip, and is conical and acute. The 

 flower-stalk is 4-5 times as long as the ovate bract, 

 and erect in fruit. The plant is 4-8 in. in height, 

 and flowers between July and September, being a 

 herbaceous perennial. 



Utricularia Bremii, Heer. This species is 

 found in Scotland in Nairn, Moss of Inshoch, 

 and Moray, Loch of Spynie, Elgin, Gordon Moss, 

 Berwickshire. From the Lesser Bladderwort it 

 differs in the larger flowers, which have a short 

 conical spur, and a flat, rounded lower lip. The 

 habit is also more robust. 



ORDER LABIATE 



Horse Mint (Mentha hirsuta, Huds. = M. aqua- 

 tica, L.). The habitat of this plant is river-sides, 

 marshes, moist places. The habit is erect. The 

 plant is usually softly hairy. The stems are 

 4-angled. The leaves are ovate to oblong- or 

 heart-shaped, the upper ones bract-like, not so 

 long as the flowers, stalked, coarsely toothed, 

 hairy both sides, opposite. The flowers are lilac, 

 in axillary and terminal, dense, capitate spikes, 

 which are ovoid, round, oblong, continuous or in- 

 terrupted below. The ultimate flower-stalks and 

 flowers are hairy. The bracts and bracteoles are 

 awl-like to lance-shaped. The calyx-teeth are 

 slender. The calyx is glandular, smooth, tubular. 

 The plant is 1-5 ft. high, flowering in August and 

 September, and is a herbaceous perennial. 



Mentha alopecuroides, Hull = M. velutina, Bab. 

 The habitat of this plant is waste places. There 

 are subterranean stolons. The leaves are very 

 broad, more or less heart-shaped below, coarsely 

 toothed, rather wrinkled above, very hairy below. 

 The flowers are pink, in conical to cylindrical, 

 short, stout spikes, with lance-shaped bracts, not 

 so long as the flowers. The calyx-teeth are as 

 long as the tube. The corolla is hairy. The plant 

 is 2-3 ft. in height, and flowers in August and 

 September. It is a herbaceous perennial.
