. LEGUMINIFER®. 4 
Stem rather slender, zigzag, 9 inches to 3 feet high. Lower 
leaves on long stalks, petioles becoming shorter as they are placed 
higher on the stem; leaflets 1 to 2 inches long, rather rigid, with 
prominent veins, and an edging of soft hairs. Stipules $ to 13 inch 
long, with the free portion one-half of their length or more, herba- 
ceous except along the line of junction with the petiole. Flower- 
heads terminal, more rarely axillary, in the latter case without a 
pair of leaves beneath ; solitary or in pairs, 1 to 13 inch in diameter, 
becoming a little elongated in fruit. Flowers ? inch long, purplish- 
rose. Pod splitting longitudinally, with an ovoid smooth seed. 
Plant bright-green, slightly glaucous, sparingly hairy. The leaflets 
glabrous when fully grown. 
A taller and more straggling plant than T. pratense, with larger 
and firmer leaflets, very different stipules, and deeper-coloured 
flowers. 
Zigzag Trefoil, Cow Clover, Meadow Clover, Marl Grass. 
French, Z'réfle intermédiaire. German, Iitilerer Klee. 
This species is sometimes cultivated in England as a fodder plant, but it is not 
generally a favourite, being less productive than the Red Clover and more difficult to 
extirpate when once grown. Its chief recommendations seem to be that it will resist 
drought and thrive on cold tenacious soils. Some writers, such as Sinclair, recommend 
it as preferable to any other species for permanent pasture on light dry soils. 
SPECIES IV.—TRIFOLIUM OCHROLEUCUM. Linz. 
Pirate CCCX LIX. 
Rootstock branched, producing tufts of leaves, and nearly 
straight ascending simple or very slightly branched stems. Leaves 
distant ; leaflets obovate, oval, or elliptical, those of the lower 
leaves notched at the apex; all finely denticulate on the margins, or 
almost entire. Stipules sub-herbaceous, with few veins which do 
not anastomose, adnate for about one-half their length, with 
the free portion lanceolate-acuminate. Uppermost leaves oppo- 
site, a little way below the flower-heads, with dilated stipules. 
Flower-heads ‘shortly stalked, terminal, globose, at length ovoid. 
Calyx-tube 10-ribbed, with the throat nearly closed by 2 opposite 
callosities resembling lips; teeth rather slender, lanceolate-sub- 
ulate, with a thick central nerve; upper 4 shorter than the 
calyx-tube, the lower one three times as long as the upper ones, 
becoming rigid and spreading, but scarcely enlarged in fruit. 
Corolla twice as long as the calyx. Plant pubescent. 
In pastures, fields, and thickets, on dry clayey or gravelly soils.
