summit of the ovary. Filaments very short and thick, subulate : anthers 

 large for the size of the flower. Seeds hispid. — Mr. Nuttall supposes this 

 species to be nearly allied to H. Richardsonii. It seems to us, however, to 

 form, with the succeeding species, a very well-marked section. 



14. H. hirtiflora : hirsutely hairy ; scape naked ; leaves cordate, some- 

 what hairy, obtusely 5-7-lobed, incisely crenate ; panicle elongated, narrow, 

 loose ; flowers small ; calyx canescently villous ; the limb flat, with short 

 and broad very obtuse lobes ; petals sjjatulate, unguiculate, somewhat cadu- 

 cous, and, with the stamens, about the length of the lobes of the calyx ; styles 

 very short. — H. hispida, Hook. 6f Am. ! hot. Beechey, suppl. p. 347, not of 

 Pursh. 



California, Douglas ! — Leaves about as large as in Tiarella cordifolia, 

 cordate -ovate, rather obtuse. Scape 8-12 inches high. Calyx-tube ad- 

 herent to the base of the ovary. Filaments subulate : anthers roundish. 



15. H. pilosissima (Fisch. & Meyer) : subcaulescent, very villous with 

 long spreading glandular hairs ; leaves ovate-cordate, ratlier obtusely lobed, 

 toothed ; pedicels shorter than the flowers ; petals nearly linear, twice the 

 length of the connivent teeth of the subglobose calyx ; stamens slightly ex- 

 serted ; styles rather included. Fisch. S^' Meyer, ind. sem. St. Pttersh. (5)

California, at the Russian colony Ross, Fischer Sf Meyer. — This plant is 

 compared with H. Americana and H. micrantha ; but it is apparently allied 

 to the preceding. 



5. TOLMIEA. Torr. S^- Gr. (not of HooTc.) 



Calyx infundibuliforra, free from the ovary, somewhat unequally 5-cleft 

 at the summit, split externally from above downwards and gibbous at the 

 base : aestivation imbricate. Petals 5, filiform, exserted, recurved, inserted 

 between the teeth of the calyx, persistent. Stamens 3, scarcely exserted, 

 inserted into the throat of the caly-x opposite the three superior lobes : fila- 

 ments subulate : anthers large, reniform, 2-celled ; the cells confluent at the 

 apex. Ovary oblong, attenuate at the base, 1-celled, with 2 parietal pla- 

 centae: styles 2, subulate: stigmas obtuse. Capsule oblong, membranaceous, 

 1-celled, many-seeded, 2-valved at the apex; the valves equal. Seeds 

 globose, very small, muricate-hispid. — A perennial herb, with fibrous roots. 

 Leaves cordate, incised ; the cauline ones alternate. Stipules adnate, scarious. 

 Flowers (rather large) in a slender elongated raceme. Bracts minute, 

 scarious. Pedicels with 2 setaceous opposite deciduous bracteoles, erect- 

 spreading in fruit.

Shady woods. Banks Island, N. W. Coast, Menzies ! and from Puget 

 Sound to the Oregon River, Douglas ! Scouler ! Nuttall .' — Stem 1-2 feet 

 high, mostly simple, slender, 3-5-leaved, hairy, as well as the leaves and 

 petioles. Leaves ovate-cordate, on slender petioles, somewhat 5-7-lobed, 

 acute, sharply incisely serrate. Raceme elongated in fruit : pedicels scarce- 

 ly as long as the flowers, recurved-spi'eading, rather erect in truit. Calyx 

 tubular-infundibuliform, with a saccate projection at the base on the lower 

 side, cleft on the same side from an early period ; the lobes rather unequal,
