8 DIAND. MONOG, 



HAD. Fields and hedge-banks, common. Fl. April to July. Q. 



Stems weak, procumbent. Leaves rather fleshy, slightly hairy ; ter- 

 minal lobe the largest : upper leaves sessile. Peduncles longer than 

 the leaves, recurved when bearing fruit. Cor. pale blue with darker 

 veins. Caps, of two turgid glabrous lobes. Seeds large, two in each 

 cell. 



5. PINGUICULA. 



1. P.vulgaris (common Butterwort], spur cylindrical acute as 

 long as the veinless petal, upper lip 2-lobcd, lower one in 

 three unequal obtuse segments. Lighlf. p. 76. E. B. I. 70. 



HAS. Marshy places and wet sides of mountains, common. Fl. June. I/ . 



VVTiole plant covered with minute crystalline raised points. Leaves 

 radical, ovate, fleshy, the margins singularly involute. Scapes single- 

 flowered. Flowers drooping, purple, palate hairy. S tarn, two, short, 

 white, thick, curved 3 one on each side the rounded germen. An- 

 thers one-celled, vertical. Style short. Stigma very curious, large, 

 expanded, fixed at the margin and spurred behind, covering the an- 

 thers with its broad disk, and bent down over them. Caps, ovate, 

 one-celled, bursting half-way into two short valves. Seeds nume- 

 rous, small, fixed to a central column or receptacle. Near P.gran- 

 diftora of E. B., but that is twice as large, especially in the flower, 

 which is beautifully veined. In the form of the corolla there unfor- 

 tunately appears to be little or no difference. 



2. P. Lusitanica (pale Butterwort}^ spur obtuse curved shorter 

 than the corolla, divisions of the petal nearlv equal, leaves and 

 scape hairy. Lightf. p. 77 (P villosa). ' K. B t. U5 



HAS. Marshes and wet moors towards the north -west coast of Scot- 

 land and the Isles, not uncommon. Isle of Skie. Lighf. Bute and 

 Arran, Mr. Murray. Isle of Mull and west coast of Ross-shire : 

 but no where have I seen it so plentiful as in Sutherland, upon the 

 wet moors adjoining Cape Wrath, growin with Arbutus alpina and 

 Jungermannia cochleariformis . Fl. July, August. 11 . 



Much smaller than, and altogether very different from, the preceding. 

 Leaves far less succulent, marked with purplish reticulated veins. 

 Cor. with a faint purple tinge j throat yellow. Found only in Por- 

 tugal, Scotland, Ireland, and very rarely in England. In our island, 

 confined wholly to the western side. 



6. UTRICULARIA*. 

 1. U. vulgaris (greater hooded Milfoil), spur conical, upper 



lip as long as the projecting palate, leaves pinnato-multind. 



Lightf. p. 77. E. B. t. 253. 

 HAB. Ditches and deep pools. Fl. June, July. I/ . 



' The British species of this highly curious and beautiful genus are all 

 aquatics : their roots, stems, and even leaves being furnished with numerous 

 membranaceous, reticulated vesicles, which, according to Heyne, are filled 

 with water till it is necessary the plant should rise to the surface and expand 

 its blossoms above the fluid. The vesicles are then found to contain only air, 

 which again gives place to water when the plant descends to ripen its. seeds 

 dt the bottom.
