238 COROLLIFLORjE 



2. A. tcnella (Bog Pimpernel). — Stem creeping ; leaves roundish, 

 stalked, shorter than tlie flower-stalks. A beautiful little prostrate 

 plant, with slender stems 4-6 inches long, small leaves which are 

 arranged in opposite pairs, and erect rose-coloured flowers, larger 

 than those of the Scarlet Pimpernel. Boggy ground and sides of 

 rivulets ; common. — Fl. June to August. Perennial. 



5. Lysimachia {Loosestrife) 



1. L. nuinmiilaria (Money-wort, Herb-twopence, Creeping 

 Jenny). — Stem creeping ; leaves roundish, .slightly stalked ; flowers 

 solitary, axillary. A very pretty plant, well marked by its opposite, 

 shining leaves and large yellow flowers. The stems grow from 1-2 

 feet in length, and hang from the banks of fivers in a very graceful 

 way. This plant is much used to ornament rock gardens. Banks 

 of rivers and damp meadows; common. ^FI. June, July. Per- 

 ennial. 



2. L. nemormn (Wood Loosestrife, Yellow Pimpernel). — Stem 

 spreading ; leaves egg-shaped, acute, on short stalks ; flowers soli- 

 tary, axillary. Approaching the Scarlet Pimpernel in habit, but 

 somewhat larger ; the flowers are bright yellow and very pretty. 

 Woods ; common. — Fl. June to August. Perennial. 



3. L. vulgaris (Great Yellow Loosestrife). — Stem erect, branched, 

 downy ; leaves tapering to a point, opposite, or 3-4 in a whorl ; 

 flowers in terminal panicles. Very different in habit from either of 

 the preceding, growing quite erect, 2-3 feet high, with terminal 

 panicles of rather large yellow flowers. Banks of rivers ; common. 

 — Fl. July. Perennial. 



4. L. thyrsiflora (Tufted Loosestrife). — Resembles L. vulgaris in 

 habit, but bears its flowers, which are small and yellow, in numerous 

 dense dusters. It grows in the north of England and parts of 

 Scotland, but is rare. — Fl. June, July. 



6. Centunculus {Chaffweed) 



I. C. minimus (Chaffweed). — The only British 



species. One of the smallest among British plants, 



rarely exceeding an inch in height, and often much 



less. It is nearly allied to the Pimpernel, and at 



the first glance might be taken for a stunted spiecimen 



of the common species. The leaves are egg-shaped, 



acute ; the flowers sessile, axillary. It is sometimes 



branched, but very frequently consists of a single 



stem, 6 or 8 leaves, and as many inconspicuous 



Centunculus flowers. It grows in damp gravelly places, especi- 



MiNiMus ^jjy where water has stood during the winter, — 



{Chaffweed) ^l June to August. Annual.
