Order 35. SAXIFKAGACE.S:. (Saxifrage Family.) 



Herbs or shrubs, of various aspect, distinguishable from Rosacese by hav- 

 ing copious albumen in the seeds, opposite as well as alternate leaves, and 

 usually no stipules when the leaves are alternate ; the stamens mostly definite, 

 and the carpels commonly fewer than the sepals, either separate or partly 

 so, or all combined into one compound pistil. Calyx either free or adher- 

 ent, usually persistent or withering away. Stamens and petals almost al- 

 ways inserted on the calyx. Ovules anatropous. — A large family, to 

 which Parnassia, formerly associated with Drosera, is commonly referred, 

 — now made to include Ilibes also. 



Tribe I. GKOS.SVL.ARIE.K. Shrubs, with alternato and palmatcly veined and lobed 

 leaves : stipules none or united with the base of the petiole. Calyx-tube coherent with the 

 one-celled ovary, which has 2 parietalplacentre and forms a many-seeded berry. Seed-coat 

 externally pelutinous. Embryo minute at the base of the hard albumen.

 Tribe III. II YDR ANGIKiG. Shrubs or trees, with opposite simple leaves, and no 



stipules. Ovary 2 - 5-cclIed ; the calyx coherent at least witli its base. Fruit (in the fol-

Stiimens 8 or 10.

latter convolute in the bud. Stamens 20-40. 

 Tribe IV. SAXIFRAGE.^. ITerbo, withunt stipules, except p<Thaps a niomhranous 

 dilatation of the base of the ])etiole. Petals imbricated or rarely convolute in the bud. Fruit
