DECANI). PENTAGYN, 145 



roundish, depressed, globose, dotted with raised points ; varying 

 extremely in the breadth of the margin. Such as is figured in the 

 S. pentandra of Sm. is very common. I should even doubt if the 

 foreign pentandra be distinct from this ; though its margin is, as 

 Wahlenberg says, " broad, membranaceous, pellucid, and striated in 

 a radiated manner 5" and differing from S. arven$is,as Smith justly 

 observes, as Arenaria marina does from A. rubra. In the present 

 case, however, intermediate states are common. 



2. S. nodow (knot ted Spurrey), leaves subulate opposite glabrous 

 connate the lower ones sheathing upper ones bearing clusters 

 of young; leaves, petals much longer than the cak Lightf. 

 p. 244. ^E. B. f.694. 



HAB. Wet sandy places, by the sides of lakes and marshes. Bog be- 

 yond Fossil, plentiful, and banks of the Clyde at Bowling bay, Hopk. 

 Fl. July, Aug. H . 



Three to four inches high, branched and decumbent at the base, where 

 the leaves are three quarters of an inch long, but gradually becom- 

 ing smaller upwards. Flowers large, white, two or three on the 

 terminal branches, peduncled. Whole plant glabrous. Cal. nerve- 

 less. 



3. S. sululata (awl-shaped Spurrey}, leaves subulate subciliated 

 tipped with a bristly point, peduncles solitary very long, pe- 

 tals and capsule as long as the calyx. Lightf. p. 2-H (S. la- 

 rid?) a). E.B. t. 1082. 



HAB. Dry pastures, gravelly and stony places. Pastures W. of Mug- 

 doch castle, Hopk. Hills S. of Newburgh, Fifeshire- Craig Rossie, 

 one of the Ochil hills, plentiful, D. Don. Near Forfar, G. Don; 

 Fl. June, July. 7/ . 



Small plant, scarcely two inches high, branched and decumbent at the 

 base j each branch terminating in a flowerstalk 1 inch long, with 

 a small flower, which is erect when expanded, but generally droop- 

 ing before and after. I fear the glandular hairs figured by Curtis, 

 and upon which so much reliance is placed by Smith, will afford no 

 character, as I have specimens (cultivated ones it is true) perfectly 

 glabrous in every part. It approaches very near the following spe- 

 cies ; but is smaller, paler green, has a decided bristly point, and the 

 caps, is much shorter. 



4. S. saginoides (Pearl-wort Spurrey), glabrous, leaves subulate 

 acute awuless, peduncles solitary very long, flowers drooping, 

 petals as long as the cal., caps, twice as long. E.B. I. 2105. 



HAB. Mountains. Upon Mael-ghyrdy, where I believe it was first 

 discovered in Britain by G. Don. Clova and other Highland moun- 

 tains, D. Don. Fl. June. 7/ . 



This, as well as the last, has much resemblance to Sagina procumbens. 

 Wahlenberg says it is readily distinguished from S. subulata by its 

 drooping flowers. But according to the E. Bot. figure this cha- 

 racter does not seem to be constant.
