182 THE PEATLOWEE TEIBE. 



ing stems, attaining 3 to 5 or even 6 feet, the angles expanded into narrow 

 green wings. Leafstalks also flattened or winged, ending in a branched ten- 

 ilril, and bearing a single pair of long lanceolate leaflets. Stipules narrow. 

 Peduncles 6 inches long or more, bearing a loose raceme of rather large 

 flowers of a pale reddish-purple ; the standard very broad, with a green spot 

 on the back, and the keel also partially green. Pod 2 or 3 inches long or 

 even more. Seeds numerous, slightly flattened. 



In hedges, thickets, and bushy or rocky places, scattered over the greater 

 part of Europe except the extreme north, but chiefly abundant in the south. 

 Occurs m many looaUties in England, but probably not indigenous in Scot- 

 land, and not recorded from Ireland. Fl. summer, often lasting late. The 

 everlasting Pea of our gardens is a broad-leaved vaiiety from southern Eu- 

 rope, with larger, more richly coloured flowers, and some slight difierence in 

 the seeds. It has been distinguished as a species, imder the name of L. la- 

 tifolius (Eng. Bot. t. 1108), and, escaping from cultivation, wUl often esta- 

 blish itself in the vicinity of garden*. 



6. Marsh Pea. Itathyrus palustris, Linn. 

 (Eng. Bot. t. 169.) 



A glabrous, somewhat chmbing perennial, not half the size of the ever- 

 lasting P., and the wings of the stem much narrower. Stipules half-sagit- 

 tate. Leaflets oblong-lanceolate, 2 to 4 pairs to each leaf, the tendril usually 

 branched. Flowers smaller and not so broad as in the everlasting P., of a 

 bluish-purple colour, fr-om 2 to 8 in the raceme. Pod glabrous, rather more 

 than an mch long. 



In moist meadows and boggy places, in northern and central Europe, 

 Russian Asia, and northern America. Dispersed over a few locaUties in 

 England, but only a very doubtful inhabitant of Scotland or Ireland. Fl. 

 summer. 



7. Sea Pea. laathyras maritiiuus, Bigel. 

 {Pisum, Eng. Bot. t. 1046.) 



A glabrous, rather stout, branching perennial, with a creeping rootstock, 

 and ehai-ply angular spreading stems about a foot long. Stipules broad and 

 leaf-like, sagittate at the base, botli sides nearly alike. Leaflets 5 or 6 pairs 

 to each leal, those next the stem often 2 inches long by 1 broad, the tendril 

 simple or branched. Peduncles about the length of the leaves, with a raceme 

 of 6 to 8 large flowers of a bluish purple. Pod hairy, at least when young, 

 1 to 2 inches long. 



On gravelly seacoasts, in northern and Arctic Europe, Asia, and Ame- 

 rica, not extending southwards in Europe beyond the shores of Picardy. 

 Occurs in a few localities on the coasts of southern and eastern England, 

 of Shetland, and of Kerry in Ireland. Fl. summer. 



8. Tuberous Pea. Latbyrus macrorrbizus, Wimm. 

 {Orobns tulerosus, Eng. Bot. t. 1153.) 

 Kootstock perennial, forming small tubers ; the annual stems glabrous, 

 nearly erect, simple or nearly so, 6 inclies to a foot high. Leaves without 

 tendrils ; the leafstalk ending ui a fine point, or sometimes in a narrow 

 leaflet ; the leaflets usually 2 pairs, sometimes 3 or even 4 pairs, oblong-lan- 

 ceolate or linear. Peduncles slender, bearing a loose raceme of 2 to 4 flowers 

 of a bright reddish-purple. Pod glabrous, about 1^ inches long. The whole 

 plant dries black Uke the following species.
