204 BOBAGINACEJE. 



The Creeping Water Scorpion-grass (M. repens), varies little 

 from tliis, except in having leaves in the cluster. I have not 

 found a specimen. 



The Wood Scorpion-grass (M. sylvatica), is a lovely plant, 

 scarcely inferior in charm to the Water one. It covers our 

 northern woods with starry gems in April and May, growing a 

 foot high. I believe it is a very local plant. Its leaves are 

 smaller than those of the true Forget-me-not, and of a very 

 dull green. The clusters are full and brilliant. 



The Field Scorpion-grass (M. arvensis), is a small plant with 

 tiny sky-blue flowers. It blooms all the summer months, and 

 is common in corn fields, hedgebanks, and waste places. 



The Early Field Scorpion-grass (M. collina), grows on Black- 

 ford Hill, near Edinburgh. I found it in March ; it was only 

 an inch high, and its flowers were proportionately small, and 

 of a very bright blue. Fanny has also specimens of it which 

 she gathered on banks and rocks near Clevedon. 



The Yellow and Blue Scorpion- grass (M. versicolor), she 

 found near Polperro. The flowers of this species are also 

 small ; but the plant is easily distinguished by having some of 

 the blossoms blue, and the freshly- opened ones yellow. These 

 three last-named Scorpion-grasses are annuals. 



The Tufted Scorpion- grass (M. ccespitosa), is perennial. It 

 grows in wet places ; Edward has it from Kent, and I from 

 the county of Durham. Its only fault is that there is too 

 much foliage for the small spikes of pale blossoms. The 

 leaves are pale and hairy, and the stems thick, and sometimes 

 a foot high. 



The Bock species (M. rupicola), has a very handsome blos- 

 som, large, and intensely blue. The stems are tufted. It is 

 found on mountains, but mine is a garden specimen. 



The Little Mudwort (Limosella), is a prostrate plant, bristly, 

 and with crowded leaves, and very small blue flowers. I have 

 sought it in such low pastures as it is said to inhabit, but in 

 vain.
