PRIMULACEJE. 541 



Iii woods, on banks, and under rocks, in southern Europe and west- 

 ern Asia, and, having been long cultivated in flower-gardens, has esta- 

 blished itself in a few localities in southern and eastern England. Fl. 

 autumn. In its native country it varies much in foliage, in the precise 

 shape of the orifice of the tube and of the lobes of the corolla, as well 

 as in the time of flowering ; and it is believed that two at least of the 

 supposed species founded upon these differences, have been gathered 

 in England apparently wild. Between ten and twenty forms, mostly 

 varieties of the common C, are in cultivation. 



IV. XiYSIMACHXA. LYSIMACHIA. 



Perennials, with erect or trailing stems, opposite or whorled leaves ; 

 the flowers usually yellow, either solitary on axillary pedicels or col- 

 lected in terminal or rarely axillary racemes or clusters. Calyx deeply 

 5-cleft. Corolla rotate or campanulate, deeply 5-lobed. Stamens 5. 

 Capsule opening in 5 or 10 valves. Occasionally the parts of the 

 flower are in sixes instead of fives. 



A considerable genus, spread over the northern hemisphere in Eu- 

 rope, Asia, and America. 

 Stems erect. Peduncles many-flowered. 



Leaves ovate-lanceolate. Flowers in short terminal 



panicles. Lobes of the corolla broad 1. Common L. 



Leaves lanceolate. Flowers in axillary racemes. Lobes 



of the corolla narrow and short 2. Tufted L. 



Stems procumbent or trailing. Peduncles 1-flowered, 

 axillary. 

 Flowers large, almost campanulate. Calyx-segments 



broad 3. Moneywort L. 



Flowers small, rotate. Calyx-segments very narrow . . 4. Wood L. 



Besides the above, the fringed L. (L. ciliata, Eng. Bot. Suppl. 

 t. 2922), a North American species, has been gathered apparently wild 

 in Cumberland and near Dumbarton. It is an erect plant, like the 

 common X., but with fewer flowers on longer pedicels, the corolla 

 more rotate and paler coloured, fringed at the edge, and the stamens 

 free and spreading. 



1. Common Lysimachia. Lysimacnig, vulgaris, Linn. 



(Fig. 6±6.) 



(Eng. Bot. t. 761. Loosestrife.) 



Stem erect, branched, 2 to 3 feet high, and more or less downy. 

 Leaves usually in whorls of 3 or 4, rather large, broadly lanceolate or
