56 CARYOPHYLLE& [CERASTIUM. 



Alpine and subalpine rocks, England, Wales, and Scotland ; ascending to 

 n ar 4,000ft.; absent from Ireland; fl. June-Aug. Habit of C. 

 but leaves much broader and flowers fewer and much larger, f-1 in. diam., 

 with scarcely any glands ; and capsule almost twice as long as the sepals. 

 DISTRIB. Mountains of Europe, N. America, and all Arctic regions. 



VAR. 1, laHa'tum, Lamk. (sp.); covered with long woolly hairs. VAH. 2, 

 pubesfcens, covered with short hairs. 



8. C. latifo'liumj Sm. ; stems hairy all round, leaves ovate or oblong 

 obtuse pubescent, flowers usually solitary, lower bracts herbaceous, sepals 

 obtuse margins broadly membranous, seeds obtusely tubercled. 



Alpine rocks in Wales and Scotland, ascending to 3,600 ft., rare ; fl. May- Aug. 

 Very like C. ulpinum, perhaps a sub-species of that plant ; it does not 

 precisely accord with the Continental C. l/'Jijni'iiim (itself too near <///>/ '/), 

 and is altogether a very doubtful species. DISTRIB. (of the European form), 

 Alps and Arctic regions, from Lapland to Italy, and from France to Austria ; 

 Greenland and Arctic America. 



VAH. 1, Smith' ii ; yellow-green, loosely tufted, glandular and hairy, sepals 

 almost eglandular. C. latifolium, Sm. N. Wales and Scotch Alps. VAR. 

 2, compaJtum, Syme ; light green, densely tufted, glandular and hairy, 

 sepals glandular. Braemar. VAR. 3. Edmondstondi, Watson (var. /</<//(.- 

 cens, Syme) ; deep green, wanting the articulated hairs, stem-leaves broader, 

 sepals broader and glandular. Unst in Shetland. 



9. C. trigy'num, Villars; stem with alternating hairy lines, leaves small 

 narrow oblong-lanceolate glabrous, cymes 1-3-flowered, bracts herbu<-r,,u* 

 margins broadly membranous glandular or glabrous. Stella'ria ccrastoides, L. 

 Alpine and subalpine rills and springs in Scotland, ascending to 3,700 ft., rare ; 



fl. July-Aug. A smaller and more delicate species than the two preceding 

 alpine ones, nearly glabrous. Leaves |-Jin., distant, obtuse, often recurved. 

 Flowers ^ in. diam., on very slender pedicels. *!*/>/<* linear-oblong, spread- 

 ing, 1-nerved. Petals deeply 2-fid. Styles 3-5, usually 3. Capsule longer 

 than the sepals.- DISTRIB. Alps of Europe (Arctic), Siberia, W. Asia to 

 the Himalaya, all Arctic regions. Altogether intermediate between Ceras- 

 fi'iin and Stellaria. 



7. STELLA'RIA, L. SxiTCQWORT. 



Slender usually glabrous herbs. Leaves grassy or broad. Flovvrx in 

 dichotornous cymes, white, small. Sepals 5, rarely 4. Petals 5, rarely 



4, 2-lid or 2-partite. Stamens 10, rarely 8, more or less perigynous. /W. 

 annular, sometimes divided into glands. Ovary 1-celled ; styles 3 ; ovules 

 many. Capsule short, splitting below the middle into as many simple 

 or 2-fid valves as there are styles. Seeds compressed, granulate ; embryo 

 annular. DISTRIB. All temp, and cold regions; species 70. KTY.M. 

 Stella, in allusion to the ster-like flowers. 



SECTION 1, Mala'chium, Fries (gen.). Sepals free to the base. Styles 



5, rarely 3. Capsule with 5 2-fid valves. 



1. 8. aquat'ica, Scopoli ; slightly glandular above, stems diffuse 

 decumbent angular, leaves ovate-cordate. Cerastium aqiiaticum, L. 

 Borders of ditches, streams, &c. from Cheshire southwards ; fl. July-Aug. 



Perennial, titem 1-3 ft., brittle, branched, trailing over bushes. 



1-1 ^ in., membranous, lower shortly petioled, acute, sometimes ciliate.
