 bose upon long lateral stalks, calyx after flowering inflated mem- 

 branaceous reticulated downy with two of the teeth bent down, 

 stem creeping, leaflets obcordate serrated. E. Bot. t. 1050. 



Meadows and pastures. Fl. July, Aug-. 1^. — Flowers very small, 

 purplish-red. The heads of flowers, an inch in diameter, are often 

 more or less coloured, so as not unaptly to represent a Strawberry. Mouth 

 of the calyx, as in the following species, singularly contracted when en- 

 closing the fruit. 



15. T.*resupindtwn,'L. (reversed Trefoil); heads hemisphserical, 

 at length globose, on stalks at first only about as long as the peti- 

 ole, corollas resupinate, calyx after flowering membranaceous re-

Dry pastures and borders of fields, frequent. — P>. In sandy soil. Near 

 Edinb. Fl. June, July.0. — This is well distinguished from the following 

 by its large, dense, hop-like heads oi flowers, and the standard which is 

 striated when old. It is more difficult to distinguish the erect var. (i. 

 from the true T. agrariian of Linn. That plant is however larger and 

 stronger in all its parts, and has oblong nearly sessile leaflets, which are 

 much shorter than the peduncles. 



17. T.filifdrme, L. (lesser yelloiv Trefoil); heads of (ew lax 

 somewhat racemose flowers, standard with its sides at length de- 

 flexed nearly even, leaves almost sessile, leaflets obcordate, cen- 

 tral one mostly on a short stalk, stems procumbent a. major ; 



larger, heads many-flowered, peduncles much longer than the 

 leaves. T. filiforme, Sturm, Deutschl. FL cum Ic. and foreign 

 authors. — T. mi?ius, JRelh. — E. Bot. t. 1256. — j3. microphyllum, 

 (DC. Prod. V. ii. p. 206.); smaller, heads of a very few distant
