190 DECANDRIA — PENTAGYNIA. [Sperguht. 



Mountains of Walcf5 and Scotland. Cloywyn y Garnodd, near Llan- 

 beris ; Snowdon, but rare. Very rare on Ben Lomond ; more frequent 

 on Ben Nevis. Fl. July, Aug. y.. — Never clothed witli lon<j wbite 

 hairs; of a deeper green than C. o/yjz«?/>«, sometimes almost glabrous. 

 The stems are dichotomous an(i bare of leaves below, and much buried 

 under rocks and stones. Flowers solitary, rarely 2, terminal on the 

 branches. — I agree with Mr W. Wilson in thinking that there exists 

 scarcely any difference either in the flower and fruit between this and 

 the preceding. In both, the capsules are broadly oblong, shining, nearly 

 twice as long as the calyx, straight, opening with 10 teeth. 



8. C. aqudlicuni, L. (ivater Chickiceed); upper leaves cordato- 

 ovate sessile, flowers solitary, fruit pendulous. E. JSot.t. 538. 



Sides of rivers and ditches. Fl. July. If..— Stems 1—2 feet long, 

 branched and straggling. Leaves large, lower ones only on footstalks, 

 with short scattered hairs on their surface and margins ; whilst in Stel- 

 laria nemorinn, (to which it is closely allied,) besides that the latter 

 species has but 3 styles, the leaves are only ciliated on the margin, and 

 appear when seen under the microscope to be very minutely dotted vvith 

 raised points. Stems viscid upwards. The capsule opens vvith 5 teeth 

 or valves. 



20. Spergula. Linn. Spiirrey. 



1. S. arvensis, h.(Co7-n Spurrey'); leaves whorled with minute 

 membranaceous stipules at their base, stalk of the fruit reflexed, 

 seeds more or less margined. E. Bot. t. 1536. — S.pentandra, E. 

 Bot.t. 1535. 



Corn-fields, too frequent, especially on light stony soils. Fl. June — 

 Aug. 0. — Stems 6 — \'l inches high, swollen at the joints. Leaves 1 — 2 

 inches long, narrow, linear, terete, glabrous or a little pubescent, in two 

 fascicles from each joint.spreading in a whorled manner. Panicle of many 

 jiowers. Pet. white, ovate, rather longer than the calyx. Stam. often 

 5. Seed varying exceedingly in the width of its margins. — Cattle are 

 fond of this plant, and it is an object of culture in Holland. 



2. S. nodosa, \j. {hiotted Spurreij) ; leaves subulate opposite 

 glabrous connate, the lower ones sheathing, upper ones bearing 

 clusters of young leaves, petals much longer than the calyx. E. 

 Bot. t. 694. 



Wet, sandy, and marshy places, frequent. Fl. July, Aug. If. — 3 — 4 

 inches high, branched, and decumbent at the base, where the leaves are 

 J of an inch long, but they gradually become smaller upwards. Floicers 

 large, white, 2 — 3 on the terminal branches, peduncled. Whole plant 

 glabrous. Cal. nerveless. 



3. S. saginoides, L. (^Pearl-u-ort Spurrey); glabrous, leaves su- 

 bulate acute awnless, peduncles solitary very long, petals shorter 

 than the calyx, capsule twice as long. E. Bot. t. 2105. 



Highland mountains, frequent. Fl. June, July. If. — Stems 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. 

 Flower drooping before and after expansion ; capside erect. 



4. S. subuldla, Swartz, {awl-shaped Spurrey) ; leaves subulate 

 subciliated tipped with a bristly point, peduncles solitary very
