Herbs, mostly small perennials. Radical leaves often rosulate ; stem leaves 

 alternate' (in Sect. Porphyrimi subopposite), exstipulate, petiole sheathing at base. 

 Flmcers corymbose or paniculate or reduced to 3-1 ; white or yellow, rarely red. 

 Calyx adnate to the ovary at base (rarely free) 5-fid, imbricate. Petals 5, ^ri- 

 ynous. Stamens 10 (rarely o) perigynous. Carpels 2 (very rarely 3-5) united 

 elow, narrowed upwards into a style, stigma lateral subcapitate; ovules numer- 

 ous, axile. Ripe Carpels dry, opening at the top ventrally. Seeds small, ellinsoid 

 in Indian species. — Distrib. Species 160, almost all in the Northern Hemi- 

 sphere ; inhabiting cool temperate, and especially alpine, localities. 



Sect. I. Nephrophyllum. Calyx adnate to the base of the ovam lobes 

 erect in fruit. Petals white, much exceeding the calyx. Stems erect leafy. -R^: 

 dicdl leaves petioled, reniform, lobed. Bracts 2, unequal at base of peduncles. 

 —In the Indian species the surculi are represented by bulbils^ covered with ful- 

 voiB hairs, forming a cluster at the base of the stem. r > =^. ^ ■ • ^"' 



1. S. odontophylla, H.f. 8r T. inJourn. Linn. Soc. ii. 64; no bulbils 

 in the upper axils, radical leaves crenate with 7-12 shallow rounded lobes, lobes 

 of stem-leaves often triangular acute. Wall. Cat. 464, partly. S. asarifolia, 

 Stei^nh. Saxifi^ag, SuppL t. 24. / '

Laxly villose, 6-10 in. high. Flowers Z~%. V^^qt leaves few, sometimes 0.; in 

 the ripe /rwi^ the calyx-tube is short campanulate or funnel-shaped; the lobes are 

 ovat^-linear, approximate, with acute simises. — This species bears a general resem- 

 "blance to S.granulata, but the calyx in fruit is very diflferent. It is more difficult to 

 separate it from 8. sibirica. Engler {Monog. Saxifrag. 99) has teken Stemb, S(^- 

 frag. SuppL t. 25 as the type of S. odontophylla, which should rather be referred to 

 S. sibirica. ....-',,...

Stem pubescent, 6-8 in high. Flowers 1-10. Calyx-tube in the ripe fruit sho t 

 campanulate or funnel-shaped; lobes ovate-linear, sinuses narrow. '^'^'^^^ ^^ ^ f ^' tlan 

 angular, quite smooth, testa minutely reticulate. Flowers and capsules smaller i^ 

 those of S. odontophylla. All the Indian specimens referred to 8. granulata, \'^^^r^^ 

 H.f. 4- 7\ in Journ. Linn. Soc. ii. 63 are here reduced to 8. sibirica. In the ^ip^^^ 

 of 8. gramdata the calyx is divided only about half way down, the tube is n« 

 spherical, the lobes are oblong distant with rounded sinuses.
