 tite, stain. 5 — 10. LightJ'.p. \72 {Alsine media) . E. BJ. 537. 



Hab. Road-sides and waste places, abundant. Fl. almost the whole 

 year. G • 



Stons weak, with alternate lines of hairs between each pair of 

 leaves, which so admirably distinguish the species. Leaves on foot- 

 stalks, except the uppermost, smooth. Flowers small, white, on so- 

 litary, axillaiy and terminal stalks. — It is a good pot-herb, and 

 small birds are very fond of the seed. 



3. ^. holosiea (greater Slhchivort), stem nearly erect, leaves 

 lanceolate much acuminated finely serrulate, petals inversely 

 heart-shaped bifid twice as long as the nerveless cal. Light/'.

Hau. Woods and hedges, common. H. May. 11. 



Plant 1 or li foot high, rather rigid and brittle, somewhat glaucous. 

 Flowers large, and -witli much broader petals than the two following^ 

 pure white. Panicle of few flowers, leafy. 



A. 'S). graminea (Lesser Slitchwort), stem nearly erect, leaves 

 lanceolate acute entire, panicle much branched, petals very 

 deeply cleft, segments linear scarcely longer than the three- 

 nerved leaves of the cal. Liglitf. p. 229. E. B. t. S('3. 



Hab. Dry pastures, fields and heaths, common. Fl. May. % . 



One foot high, more slender than the last, and readily distinguishable 

 by its much smaller flowers, large and branching panicle, three- 

 nerved cal., and entire leaves, which are moreover by no means so 

 much acuminated. 



5. S. glauca [glaucoiis Marsh Slitchwort), stems nearly erect, 

 leaves linear lanceolate entire glaucous, flowers upon long so- 

 litary axillary footstalks, petals very deeply cleft their segments 

 linear much longer than the3-nerved cal. E. B. t.S25.

Fossil, Glasg., JJopk. Fl. June, July. 7/ . 

 Erpudly slender with the last, 1 foot high. Flowers next in size to 



S. holostca. Readily known from that and glatica by its narrower 



glaucous leaves, solitary axdlary flowers, and the narrower cal. 



leaves, which, like the last, are 3-nerved. 



6. S. uliginosa {Bog St itch wort), stem decumbent ovato-lan- 

 ceolate entire with a callous tip, flowers in dichotomous pa- 

 nicles, petals bipartite shorter than the cal. LighlJ. p. 220

Hab. In ditches and rivulets, frequent. Fl. June. O . 



It is strange that this should have been coulbimded with S.graminea. 

 Its much smaller size and minute petals, besides the shape of the 

 leaves, will at all times serve to distinguish this common species. 



7. S. cerastoides {aipi/ie Slitchwort), stems decumbent with an 

 alternate hairy line, leaves oblongo-spathulp.te, peduncles 2 or 

 3 mostly terminal as \ve\i as the cal., which is twice as long as 

 the bifid cor. glauduloso-pilose.
