fusely spreading and grows in matted tufts here and there. It 

 is from a region which has produced a number of little-known 

 species, and grows in company with the very rare Vioma ova/a.

This is an exceedingly interesting clover on account of the 

 stcloniferous branches bearing subterranean flowers at the axils 

 of the leaves in addition to the regular flowers. The subterran- 

 ean ones are solitary, with a pedicel about 5 mm. long. When 

 young the calyx, vexillum, wings and keel are present. The 

 calyx is more inflated, and has much shorter teeth. The other 

 parts of the flower are not unlike the regular flowers. Develop- 

 ment takes place by the vexillum, wings and keel withering, 

 and the inflated calyx surrounding the legume at the base like 

 an involucre. The legume is orbicular and about 3 mm. in di- 

 ameter, puberulent, with a few pilose hairs. It is apparently 

 four-ovuled; from one to three seeds developing. The seeds are 

 variable in shape, from elliptical-ovoid to reniform, and when 

 fully mature are mottled with purple. 



Miss Anna Stockton Pettit in her interesting paper on-the 

 peanut {Arachis Hypogaea L. ), Mem. Torr. Club, 4: 275. [895, 

 does not mention this American species of Trifolium^ but writes 

 about Trifolium subterraneum L., an European species with 

 only one kind of flowers, which develop in heads, and after flow- 

 ering "the peduncle bearing the head sinks to the ground and 

 continuing to lengthen, pushes the head under the soil." 



The distribution of T. amphianthum seems to be confined 

 mainly to the prairies of Texas. 



We would appreciate some fresh seeds, or, still better, a 

 paper from souk- one living in the region where it grows, who
