102 BRITISH BOTANY. 



Var. 7. glabratum. Stem and leaves glabrous. Reich. 4977. 



We are not acquainted with these forms, but some of our 

 readers may be. 



This plant varies much in hairiness, pubescence, and in the size 

 and shape of the leaves. It is sometimes of a deep greenish co- 

 lour ; and its mostly single large flowers and shorter capsules are 

 the only prominent characters which distinguish it from C. tri- 

 viale, which often grows beside it on the less elevated parts of 

 the Scottish mountains. 



C. latifolium, Lin. Broad-leaved Mouse-ear Chickweed. — 

 E.B. 473. L.B.s. 197. 



A. 4. C. 8. Lat. 53-59°. Alt. 0-1250 yds. Tem. 37-34°. 



Stems very short and tufted ; whole plant of a yellowish hue 

 (Smith). Leaves ovate or roundish, covered with simple glan- 

 dular hairs ; bracts herbaceous. Sepals blunt, with scarious 

 margins. Petals large, obcordate, deeply cleft. Capsule large, 

 turgid, longer than the calyx, with a very slight curvature. 

 Seeds large, rugose (Babington) . 



Alpine places in Wales and Scotland ; rare ? Per. ; June- Aug. 



Var. /S. glaciate. Stems very short ; leaves roundish. Unst, 

 Shetland. 



Var. 7. pedunculatum. Stems short, filiform ; leaves narrow, 

 lanceolate ; peduncles very long. Is this variety found iu Bri- 

 tain ? See Reich. 4974. 



C. arvense. Field Chickweed. — e.b. 93. l.b.s. 195. 



A. 12. C. 30. Lcat. 50-58°. Alt. 0-100 yds. Tem. 50-46°. 



Stems numerous, reclining and rooting below, ascending 

 above, pubescent, sometimes glandular, simple or branching, 

 leafy. Leaves linear-lanceolate or linear, recurved, rigid, often 

 with axillary fascicles of leaves. Bracts herbaceous, scarious at 

 the apex. Petals two to three times longer than the calyx, ob- 

 cordate, bifid (cleft) . Curvature of the capsule scarcely exserted. 



Dry chalky places. Per. ; June-August. 



The flowers of this species are pure white, handsome, nearly 

 as large as the flowers of Steltaria hotostea, and very similar to 

 them, but the petals are not parted to the base, as in the Stitch- 

 worts. 



C. tetrandrum. Curt. Four-cleft Mouse-ear Chickweed. — 

 E.B. 166. L.B.s. 194"^. 



Range the same as C. semidecandrum. See ' Cybele,' vol. i. p. 288.
