CLASS V. ORDER I. '^J 



Hydrophyllum Canadense. L. Canadian Hydrophyllum. 

 Leaves simple, lobed, angular, flowers in crowded 

 fascicles. 



Leaves large and broad, somewhat palmate, about seven lobed, 

 cut and toothed. Flowers much as in the preceding. — Collected 

 in the western part of the state. 



83. ANAGALLIS. 

 Anagallis arvensis. L. Scarlet Pimpernel. 



Leaves ovate, dotted beneath ; stem procumbent. 

 Sm. 



A humble but very delicate flower. Stem square, procum- 

 bent. Leaves ovate, covered on the under side with purple dots. 

 Flowers on axillary footstalks, bright scarlet. Capsule spherical, 

 bursting crosswise, a character at any time ascertained by press- 

 ing it. In England it has received the name of "Poor man's 

 weather glass," from the circumstance that the flowers close in 

 bad weather, being very sensible to changes of the air. — Com- 

 mon at South Boston. — June and after. — Annual. 



84. LYSIMACHIA. 



Lysimachia thyrsiflora. L. Tufted Loosestrife, 



Racemes lateral, pedunculated.

Stem simple, smooth. Leaves sessile, opposite, lanceolate,, 

 acute, somewhat revolute at the edges, paler and somewhat 

 downy beneath. Flowers small yellow in short rounded racemes 

 or heads supported by axillary peduncles. The American plant 

 does not appear to me to ditfer from the European. The seg- 

 ments of the corolla and stamens often vary to six and seven, as 

 in the European. — Swamps. — June. — Perennial. 



^ Subgenus Selexjcia. Capsule five valved, intermediate barren 

 filaments five . 

 Lysimachia ciliata. L. Heart leaved Loosestrife,
