CAKYOPHYLLACEiE. 131 



of the seeds in each capsule surrounded with a membranous wing 

 half the width of the seed, striated and jagged at the edges, the 

 striae being nerves running ovit into the points of the teeth. 

 Plant deep green, slightly shining, generally more glabrous than 

 S. rubra. 



I have followed Mr. A. G. More in uniting the three forms 

 enumerated as varieties above. A microscopical examination of 

 the seed shows that the roughness of var. a is not produced by 

 tubercles as in S. rubra, but by the presence of soft papillae some- 

 thing like those on the seeds of Spergula arvensis, var. vulgaris ; and 

 there is such a gradual transition in the length of the pedicels, that 

 little reliance can be placed upon that character. The scarious 

 bracts of var. a are stipules, generally not accompanied by green 

 eaves. Kindberg places his S. medium in the section with a 

 perennial root ; but Fries, in his " Summa Vegetabilium Scan- 

 dinavise," makes no correction of Koch's statement that it is 

 an annual, so that it must be supposed that he concurred in 

 this opinion. Professor Babington, in the fifth edition of his 

 " Manual," says that his S. neglectum " includes plants resembling 

 the S. medium and S. salinum of Fries," which seems to imply that 

 he is in doubt whether the forms of which he speaks be really the 

 same as Fries' plants so named ; and as I have not seen authentic 

 specimens, I can only judge from his descriptions, which aj)pcar to 

 apply to our varieties ^ and 7.

Root biennial or perennial. Ptootstock slender, branched, 

 scarcely woody. Leaves fleshy, semi-cylindrical, filiform-linear, 

 sub-acute. Stipules deltoid-ovate, dull whitish, entire. Pedicels 

 much longer than the bracts, and two to three times the length of 

 the capsule. Sepals ovate'. Petals as long as the sepals, pale lilac 

 or nearly white, concolorous. Stamens 10. Capsule longer than 

 the calyx, often twice as long. Seeds pale brown, smooth, without
