5. S. saxdtilis Wimm. (alpine P.); perennial glabrous 

 or nearly so, stems prostrate slightly rooting, central one 

 short and flowerless, leaves subulate mucronate, peduncles 

 solitary very long, petals shorter than the calyx, sepals in fruit 

 erect and close-pressed to the capsule, capsule longer than 

 the calyx often twice as long. Spergula saginoides X, • _B p

erect durinfj flowerinc:. 



/I Linn. — j8. almost quite glabrous. 



Highland mountains, frequent, l^. 6—8 — 5'/ems many from the 

 root, procumbent below, 2 or 3 inches in length. Leaves numerous 

 and rather long at the base, shorter and in remote pairs upon the 

 stem. F/ower drooping before and after expansion; cajosw/e erect, the 

 valves much more narrowed upwards than in S. procumbens. Styles 



Sometimes confounded with Arenaria ru. 

 lella, but that has the sepals conspicuously 3-nerved. 



6. S. suhuldta Wimm. {Awl-shaped P.) ; perennial, cjespitose 

 stem procumbent not rooting, leaves subulate aristate, peduncles' 

 solitary very long, petals and capsule somewhat longer than the 

 calyx.— a. leaves usually ciliated, peduncles and calyx o^landu- 

 lar-hairy, Spergula Sw. : E. B. t. 1082. _ Sagina procumbens 



S. nivalis Fries. 



Dry, gravelly, and stony pastures, not uncommon. y8. Isle of Skye 

 and Clova Mountains. 2f . 6—8. — This comes very near the last 

 species, and it is not easy at all times to discriminate between them- 

 the common form is more glandular-hairy, while the alpine state is as 

 glabrous but with all the stems elongated. Mr. W. Wilson, however, 

 cannot distinguish the Anglesea S. subulata from the Ben Lawers 

 S. saxatiUs. Both have very much the habit of S. procumbens. 



7. S. nodosa L. (knotted P.); perennial, leaves subulate 

 glabrous connate, the lower ones sheathing, upper ones bearing 

 tufts of young leaves in the axils, petals much longer than the 

 calyx. Spergula Z. : E. B. t. 694. 



Wet, sandy, and marshy places, frequent. 2^ • 7, 8.— Central stem 

 short, without flowers ; lateral ones 3—4 inches high, branched, and 

 decumbent at the base, where the leaves are | of an inch long, but they 

 gradually become smaller upwards. Flowers large, white, 2 

 the terminal branches, peduncled. Whole plant glabrous 'or some 

 times glandular-hairy. Cal. nerveless.
