68 CALYCIFLORiE 



6. Melilotus (Melilot) 



1. M. officinalis (Common Yellow Melilot). Stem erect ; leaflets 

 narrow, egg-shaped, serrated ; flowers in one-sided clusters ; petals 

 equal in length ; legumes 2-seeded, wrinkled. A branched herba- 

 ceous plant, 2-3 feet high, with light green foliage and small yellow 

 flowers ; not uncommon in waste places. Fl. June to August. 

 Annual or biennial. 



2. M. alba (White Melilot). A much less common plant than the 

 last, probably not truly indigenous, and differs from the last in 

 being usually taller and having white flowers, in which the standard 

 is longer than the wings and keel. 



7. Trigonella (Fenugreek) 



1. T. ornithopodioides (Bird's-foot Fenugreek). A small plant 

 with spreading, prostrate branches 2 or 3 inches long and small 

 flowers of a whitish colour, growing 1-3 together in the axils of 

 the leaves ; legumes 6 to 8-seeded, curved, glabrous, twice as long 

 as the calyx. Dry sandy places, not common. Fl. June to August. 

 Annual. 



8. Trifolium (Trefoil) 



1. T. incarnation (Crimson Clover). Erect, 1-2 feet high, downy ; 

 flower-heads oblong or cylindrical, crimson ; stipules membranous ; 

 leaves composed of three obovate or inversely heart-shaped leaflets ; 

 calyx with soft hairs, toothed. Much cultivated for fodder, and 

 occurs as an escape. There is also a variety with pale yellow 

 flowers. Fl. early summer. Annual. 



2. T. arvense (Hare's-foot Clover). Flowers in terminal oblong 

 heads, which are soft with downy hair ; calyx-ieelh hairy, much 

 longer than the corolla ; stem branched, erect. A very distinct 

 species, common in sandy places, especially near the sea. The 

 peculiarly soft heads, which are nearly cylindrical, and in which 

 the pale pink flowers are nearly concealed, at once distinguish 

 this from any other British species. Fl. July to September. 

 Annual. 



3. T. stellatum (Starry Clover). A low, softly hairy form, 

 with globular heads of pale yellow flowers. It occurs only on the 

 coast near Shoreham, in Sussex, and is probably only a chance 

 introduction. It is distinguished by the remarkably large calyx 

 of the fruit, which spreads in a star-like manner. Fl. early summer. 

 Annual. 



4. T. ochroleucum (Sulphur-coloured Trefoil). Flowers in dense, 

 stalked, terminal heads, which are at first hemispherical, afterwards 

 egg-shaped ; calyx-teeth awl-shaped, the lower one much the longest ; 

 lower leaflets heart-shaped, upper oblong. The whole plant is
