LEGUMINIFERZ. 61 
much enlarged and deeply ribbed in fruit, considerably longer than 
the wings and keel, not folded longitudinally except at the base, 
not keeled on the back, arched or bent down at the apex over the 
pod. Pod much narrower and much shorter than the standard. 
Style not half the length of the pod. 
In fields, pastures, roadsides, and waste places. Very common, 
and generally distributed. 
England, Scotland, Ireland. Annual. Spring to 
Autumn. 
Stems numerous, rarely solitary, the central one erect, the 
lateral ones and the branches more or less decumbent or even pro- 
cumbent, 3 to 15 inches long. ‘Leaves on short stalks; leaflets 
4, to 3 inch long, the central one inserted higher up on the common 
petiole than the lateral ones, an arrangement which rarely occurs 
in this genus. Peduncles } to 14 inch long. Heads ? inch across 
in flower, but sometimes nearly 3 inch when in fruit. Flowers 20 
to 40 in each head, 4 inch long, lemon-yellow, reflexed and 
yellowish-brown after flowering, the lowest ones almost sessile, 
the upper ones shortly pedicellate ; standard becoming about 
+ inch long, not folded together as in most of its allies, spoon- 
shaped, very much broader than the pod. Pod elliptical-ovoid, the 
style about one-quarter the length of the pod, hooked. Seed oval- 
ovoid, yellowish, shining. Brotero, as quoted by the Rev. Mr. 
Lowe, says the seeds are mostly 2, but I have not found more than 
lin the British specimens I have examined. Plant rather dull- 
green, the leaves somewhat firm, glabrous or sub-glabrous. Stems, 
stipules, and peduncles generally more or less thickly clothed with 
adpressed curled hairs. 
This species is named T. procumbens in the Linnzean Herbarium. 
The plant there named T. agrarium is the plant so called in Koch’s 
Synopsis.*

This is a common plant in dry fields and by the wayside, and is sometimes sown 
for fodder, either by itself or more usually with white clover. It varies much in luxu- 
riance of growth, being rarely more than a few inches high in the wild state ; but when 
cultivated it often equals the Dutch clover in size. All cattle seem fond of it, and 
with the white clover it may be advantageously grown, but seldom yields a good crop 
by itself ; it will, however, flourish on very poor soils, 
* MM. Soyer-Willemet and Godron, in their “ Revue des Tréfles de la Section 
Chronosemium,” contend that this is the T. agrarium of Linnzus. It may be so of 
the “‘ Species Plantarum,” but is certainly not of the Linnean Herbarium, It is the 
fashion with many botanists (especially those who have not the opportunity of con-
