132 SAXIFRAGES. [SAXIKKACA. 



few, crowded, small, campanulate, white. Calyx green ; lobes short, obtuse. 

 Capsule almost included in the calyx-tube, beaks short, suberect, exsoru-<l. 

 DISTRIB. Alps and Arctic regions of Europe, N. Asia, and N. America. 

 Though amongst a large suite of Arctic specimens of this plant some occur 

 which are inseparable from states of kyjmofdet, sub-sp. hir ta, this is usually 

 so well marked a plant that I incline to regard it as distinct. 

 12. S. hypnoi'des, L. ; flowerless shoots usually elongate, leaves 



euneate 3-5-cleft, lobes divergent acute, those of the shoots often entire, 



calyx-tube short obconic or hemispheric, lobes usually spreading. 



Alpine and subalpine districts, from N. Somerset and Glamorgan northwards ; 

 ascending to near 4,000 ft. in the Highlands ; frequent in Ireland ; fl. -May- 

 July. Tufts often forming large cushions, glabrous or glandular hairy. 

 Leaves lax or dense, with the broad compressed petioles ^-1 in.; lobes entire 

 or the lateral cleft, flat or channelled. Flowering-shoots 3-18 in., stout or 

 slender, leafy or nearly naked, their leaves simple, linear, or broad and more 

 or less lob'ed like the radical. Flowers $-1 in. diam., few or many, cam- 

 panulate, white. Sepals rarely connate above the middle, oblong linear or 

 ovate, obtuse or acute. Capsule not concealed in the calyx- tube, beaks sub- 

 erect. DISTRIB. W. and Mid. Europe from Belgium to Spain and Austria, 

 Iceland and Greenland. 



Sub-sp. HYFNOI'DES proper; leaves of flowerless shoots entire or 3-lobed, 

 leaves or their lobes narrowed from below the middle acuminate or mucro- 

 nate, calyx-lobes narrow triangular acute. Common and widely distributed. 

 VAR. 1, platypefala, Sm. (sp.) ; flowerless shoots (at flowering time) with 

 usually 3-cleft leaves and no axillary buds, flowers sometimes pink. /S. elon- 

 gella, Sm.; condensata, Gmel. VAR. 2, yemmifera, Syme ; powerless shoots 

 with simple leaves and axillary buds. S. leptopki/lla, Haw. S. pygnwea, 

 Don, doubtfully placed here in Load. Cat., is a small garden plant like 

 ccespitosa, of which nothing satisfactory is known. 



Uub-sp. DECIP'IENS, Ehr. (sp.) fide Syme; leaves of all the shoots rosulate 

 8-7-cleft, lobes abruptly acuminate, calyx-lobes ovate obtuse as long as the 

 tube. <S. ccespitosa, Koch ; palmata, Smith. Approaches S. ceettpitosa. 

 Carnarvonshire. 



Sub-sp. HIR'TA, Don (sp.); flowerless shoots short, leaves 3-lobed lobes linear 

 suddenly contracted beyond the middle acute, calyx-lobes triangular-ovate 

 subacute. Alpine rocks; S.W. Ireland. VAR. 1, hir'ta proper, Syme; 

 very hairy, sepals broad, petals obovate flat. VAR. 2,affi'it,is, Don (sp.); 

 slightly hairy, sepals narrow, petals oblong margins incurved. VAR. 3, 

 incurvifo'/ia, Don (sp.); lobes of leaves incurved obtuse, sepals subacute. A 

 doubtful form. 



2. CHRYSOSPLENIUM, L. GOLDEN SAXIFRAGE. 



Small, succulent, annual or perennial herbs. Leaves alternate or oppo- 

 site, exstipulate. Flowers minute, green or yellow, in axillary or terminal 

 cymes. Calyx-tube urceolate or obconic, adnate to the ovary ; lobes 4-5, 

 obtuse, imbricate in bud. Petals 0. Stamens 8 or 10, inserted on the 

 margin of an epigynous disk, filaments short. Ovary inferior, 1 -eel led, 

 2-lobed at the top ; styles short, recurved; ovules many, placenta* -' 

 parietal. Capsule ^-superior, :Mulie<l, membranous, opening at the top by 

 a cruciate mouth. Seeds oblong or compressed. DISTRIB. N. temp, ami 

 Arctic regions, temp. S. Ameriia; species 15. ETYM. xp"<r<Js and 

 golden spleen, of doubtful application.
