200 SAX1FRAGACEAE. 



1. T. unifoliata Hook. Stems sparingly leafy, usually several from the 

 base, "i to 2 ft. high; leaves roundish or somewhat ovate in outline, 3 to 

 5-lobed, cordate at base, 1% to 4 in. broad, the lobes crenate; cauline leaves 

 2 or 3; radical leaves long-petioled (3 to 9 in.); panicle 3 to 9 in. long; petals 

 linear-subulate or almost filiform, inconspicuous; calyx adherent only to very 

 base of ovary, its lobes minutely eiliolate. 



Shady canons and woods, only near the coast from the Santa Cruz Alts, 

 northward. 



5. HEUCHERA L. Alum Eoot. 



Perennial herbs with stout rootstocks. Leaves radical, rounded, cordate and 

 lobed. Flowering stems scape-like, or with 1 to 3 leaves, bearing an open or 

 condensed panicle of small flowers in cymose clusters. Calyx campanulate 

 or somewhat turbinate, its tube adnate to the lower i/> of the ovary. Petals 

 5, very small or wanting, when present inserted on the throat of the calyx, 

 clawed and entire. Stamens 5, ours with slender filaments. Capsule 1-celled 

 with 2 parietal placentae, dehiscent between the 2 beaks. (J. H. Heucher, 

 l<i77-1747, German Professor of Medicine.) 



Cymes loose, the pedicels longer than the flowers; calyx turbinate at base 



1. H. in i cpu nt ha. 

 Cymes close, the pedicels shorter than the flowers; calyx rounded at base 



2. H. pilosissima. 



1. H. micrantha Dougl. Flowering stems 1 to 3 ft. high; petioles and 

 stems pilose-hirsute, the leaves hirsutulous and the inflorescence glandular- 

 puberulent; leaves round- or ovate-cordate, 2 to 4 in. long, obtusely lobed 

 and crenate-toothed, on petioles as much as 10 in. long; flowers in an' ample 

 loose panicle; calyx 1 line long, shorter than the slender pedicels; petals nar- 

 rowly oblong, curving, rather shorter than the calyx. 



Coast Ranges, common toward the coast, not reported from inner Coast 

 Range; Sierra Nevada. 



2. H. pilosissima F. & M. Very glandular villous, 1 to 2 ft. high; pedi- 

 cels shorter than the flowers, these iu close clusters and panicle less ample 

 than in the preceding; calyx globular, 1% to 2% lines long. 



Near the coast, Monterey to Humboldt Co. Perhaps too near preceding. 

 H. rubescens Torr. Leaves mostly 1 in. broad or less; calyx oblong- 

 eampanulate, tinged with rose-purple. — Sierra Nevada. 



6. PARNASSIA L. Grass op Parnassus. 



Glabrous perennial herbs with entire leaves in a radical tuft. Flowers 

 solitary, white, on scape like stems, which commonly bear a single small sessile 

 leaf. Sepals slightly united at base. Petals greenish- or yellowish-veined, 

 each bearing at base a (duster of gland-tipped sterile filaments. Stamens 5, 

 alternate with the petals. Ovary 1-celled; stigmas 4 (or 3), sessile, opposite 

 the same numbei of placentae. Capsule 3 or 4-valved, the valves placenta- 

 bearing alone- their middle. Seed-coat loose, somewhat winged. (Called 

 Grass of Parnassus by Dioscorides, from Mt. Parnassus.) 



1. P. palustris L. var. californica Gray. Scape 9 to 14 in. high; leaves 

 elliptic. 1 to P., in. long, contracted at base into a petiole which is short or 

 twice as long as the blade; petals oval or obovate, d" to !> lines long; sterile 

 filaments capillary, lid to 24 in a set, united to the mid. He. each tipped with an 

 antheroid protuberance. — (P. californica Greene.) 



Rare in the Coaal Ranges: Loma Prieta; Marin Co. (cf. Erythea, \ii, 84.) 

 More common in the Siena Nevada.
