54 TUIANDRIA— TRIGYNIA. [roli/carpotl. 



52. Dioita'ria. Scop. Finger-grass. 



1. D. * sanguindlis. Scop. (Jiairy Coclis- foot or Finger-grass); 

 leaves and sheaths hairy, florets oblong glabrous their margins 

 scabrous. — Patiicmn, Li/m. — E. Bot. t. 849. 



Rare, in sandy cultivated fields : it formerly grew in Battersea fields, 

 near London. Other habitats, given in the British Floras for this plant, 

 belong, in Mr Borrer's opinion, to the next species. Fl. July, August. 

 ©. — From a span to afoot high, branched at the base, erect or ascend- 

 ing. Leaves and sheaths hairy, the latter with small tubercles from 

 ■which the hairs spring. Spikes 3 — 5, digitated. Spikelets secund, 2 

 together, ajipresscd to the flattened rachis. CaL, outer valves very 

 small ; inner nearly equal, plane, of which the ext. one is oblong, ribbed 

 and downy or slightly scabrous at the margin, ribs glabrous. 



2. D. * humifiisa, Pers. (^glabrous Cock's-foot or Finger-grass); 

 leaves and sheaths glabrous, florets ovate pubescent. Hook, in 

 E. Bot. Suppl. t. :J6I3. — Syntherisma glabrum, Schrad. Germ. 

 V. I. p. 163. t. 3./. G. 



Rare : on loose sand at Weybridge, Sussex, Mr Borrer ; who says 

 that the Ipswich D. sanguinalis is this, and w ho thinks that the Norfolk 

 and Suffolk stations, assigned to that plant in JEmjl. Fl. probably belong 

 to the present. Fl. July, Aug. 0. — Generally smaller and more de- 

 pressed than the preceding, of a purpler hue. Leaves and sheaths quite 

 glabrous. Spikes fewer, 2 — 4 in Mr Borrer's specimens. Florets more 

 ovate and more convex, outer of the two larger calycine valves purple, 

 downy, and ribbed. Richard in Pers. Sgn. appears to have been the 

 first who discriminated this as a species, and Schrader has admirably 

 described it and figured the flower. 



TRIANDRIA— TRIGYNIA. 



53. Monti A. Li7w. Blinks. 



1 . M./ontdtittf L. ( Water-Blinks or Chickweed). E. Bot. 1. 1 206. 



Rills, springy and wet places, i^/. June, July. 0. — Whole plant suc- 

 culent, varying considerably in size. Stem prostrate and rooting. Leaves 

 small, opposite, spathulate. Peduncles nearly terminal, often forked. 

 Flowers white, at first drooping. Stam. upon the corolla, short. Ger- 

 men and capside roundish. Seeds 3, subreniform, dotted. — The /3. ma- 

 jor of Willd. and De Cand. {M. repens of Gmel. Fl. Bad.) is not un- 

 common in Scotland, and is found in Caernarvonshire. 



54. HoLosTEUM. Linn. Jagged-Chickweed. 



1. H. wnheUdtum, L. (iimbelliferotis Jagged- Chickioccd); leaves 

 elliptical ovate acute, flowers umbellate, peduncle pubescent vis- 

 cid, pedicels reflexed after flowering at length erect. E. Bot. t. 

 27. — Cerastium, Huds. Sf Hook, in FL Lond. N. Ser. t. 13. 



Rare, on old walls about Norwich and Bury. Fl. April. 0. — A sin- 

 gular and interesting plant, the original Holosteum of Linnaeus. 



55. PoLYCARPON. Linn. All-seed. 

 1. P. tetraphylhim, L. (four-leaved All-seed); triandrous, pe- 

 tals notched, stem-leaves in fours, those of the branches oppo- 

 site. E.Bot. <. 1031.
