XXVI. LEGUMINOSyE : TRIFOLIE^. [ Trigonelln 



longer than the keel, stem branched from the base ascendino- 

 E. B. S. t. 2960. 



Near Thetford and 



Cambridge. 



^- 7,8. 



Flowers yellow i^ 

 British specimens, but sometimes found white abroad. Easily dlstln 



guished when in fruit. 



[M parviflora Desf, has been observed in various places about 

 "Wandsworth, but is not indigenous : it is easily recognised by its 

 subglobose very obtuse legumes which are distinctly reticulated with 

 wrinkles, and contain only one large globular seed: the racemes are 

 dense v/hen in flower but afterwards elongated and lax.] 



8. Trigonella Linn. 



Fenuo;reek. 



\ 



Cat 5-toothed; teeth nearly equal. Pet distinct; Keel 



obtuse. Ovary many-seeded. 



Legume 



straight or 



slightly 



curved, many-seeded, much longer than the calyx, 2-valved. 

 Flowers in few or many -flowered heads^ or slwrt racemes. Leaves 

 trifoliolate . — Named from rptrc, three^ and ywj^ta, an angle^ on 

 account of the corolla appearing triangular and tripetalous 

 most of the species having a minute keel. 



1. T. ornithopodioides DC. (Bird* s-foot i^.) ; peduncles 

 about 3-flowered, legumes compressed about 8-seeded nearly 

 twice as long as the calyx, leaflets obcordate toothed at the ex- 

 tremity, stems decumbent. Trifolium L, : JE, B. t. 10i7. 



Dry sandy pastures, mostly near the sea, not very general. 0, 

 6, 7. — iS'/ems spreading, 2 — 5 inches long. Flowers small. Wi7igs 

 considerably shorter than the standard 3,nd longer than the keel; but 

 the latter is longer than the calyx and cannot be called minute in this 

 species : still the distinct petals and long legumes accord better with 

 this genus than with Trifolium. 



9, TuiroLiTJM Li7in, Trefoil. Clover. 

 Cal 5-toothed ; teeth unequal. Wings united by their claws 



to the obtuse keel^ persistent. 



Legume 1 



4-see(led, indehis 



cent, about as long as the calyx by which it is enclosed.— 

 Flowers capitate. Leaves trifoliolate . — N^amed in allusion to 

 its 3 leaves or leaflets. 



* Flowers pedicellate (white or red(lisJi)^ at length defexed; corolla at 



length scarious. 



1. T. repens L. (white T., or Dutch C.) ; heads umbellate 

 globose, legumes with 4 seeds, calyx-teeth unequal, leaflets ob- 

 cordate serrulate, stems creeping. E. B. t. 1769. 



Meadows and pastures, frequent. 1^. 5—9. — Peduncles \ong^^ 

 than the leaves. Heads oi flowers white; each flower is on a too - 

 stalk which becomes recurved after flowering, and then all the ^^^"Jf/ 

 are drooping and covered with the withered brown coroUc^s^
