Two-leaved Mitella. Fl. Apr. May. Clt. 1731. Pl.fto j ft. 



2 M. NU V DA (Lin. spec. 580.) plant usually stoloniferous ; 

 radical leaves reniformly cordate, thin, bluntly lobed, crenated, 

 and somewhat ciliated ; scapes slender, leafless ; calyx spread- 

 ing : petals pectinately jagged ; ovarium joined to the calyx 

 only at the very base. I/ . H. Native of Canada, from Lake 

 Huron to the Arctic Sea ; and from Hudson's Bay to the Rocky 

 Mountains ; and of Siberia, at the river Lena. M. reniformis,

 Flowers white. The plant here characterised is the acknow- 

 ledged M. cordifolia of all American botanists. A comparison 

 of it with the figure of Gmelin will show that it is the same with 

 his species, and consequently the M. nuda, Lin., and among the 

 numerous specimens gathered by travellers in North America, 

 many throw out runners, which again bearing leaves and scapes, 

 the plant becomes the M. prostrata of Michx.

3 M. TRI'FIDA (Graham, in edlnb. phil. journ. June, 1829. 

 Hook. fl. bor. amer. 1. p. 241. t. 82.) radical leaves cordate, 

 bluntly lobed, crenated ; scapes leafless ; flowers pentandrous ; 

 calyx campanulate, with a spreading limb ; petals trifid ; ovary 

 adhering to the calyx only at the base. I/. H. Native of 

 Nortli America, in alpine rivulets north of the Smoking River, 

 on the east side of the Rocky Mountains, in lat. 56, but rare. 

 Plentiful in woody situations, on the low ridge of the Blue 

 Mountains of Lewis and Clark's River, west of the Rocky 

 Mountains, in lat. 46. M. parviflora, Dougl. mss. Flowers 

 white. This species has the petals similar to those of Tellima 

 parviflora. Differs from the rest of the species in the petals 

 being trifid, and in the stamens being only 5 instead of 10, op- 

 posite the lobes of the calyx. Perhaps a species of Drum- 

 mondia. 



7Vj/M-petalled Mitella. Fl. May. Clt. 1829. PI. \ to 1 ft. 



Cult. The species of Mitella are pretty plants, well suited 

 for the front of flower-borders, or to grow on rockwork. They 

 are readily increased by dividing. Any light soil suits them, 

 although they grow most luxuriant in a peat soil. 



VI. TE'LLIMA (an anagram of Mitella ; separated from it).

 Dougl. in bot. reg. 1178. Hook. fl. bor. amer. 1. p. 239. D. C. 

 prod. 4. p. 49. 



LIN. SYST. Decandria, Digynia. Calyx adnate to the ova- 

 rium at the very base, having the free part inflated, ovate, and 

 5-toothed (f. 49. 6.), and the adhering part conical. Petals 5 

 (f. 49. c.), inserted in the calyx, jagged. Stamens 10 (f. 49. a.). 

 Styles 2-3, distinct from the base : stigmas subcapitate, angular. 

 Capsule adnate to the calyx at the base : the other half supe- 

 rior and furnished with the permanent flower, 1 -celled, 2-valved 

 at the apex ; placentas parietal, many seeded (f. 49./.). This is 

 an intermediate genus between Heuchera and Vahlia ; it differs 

 from Mitella in the styles being distinct, and the different habit. 

 Perennial herbs. Leaves all radical, roundish, cordate, bluntly 

 lobed, in T. parviflora compound, toothed, and hispid. Flowers 

 of a dirty red-colour, rather large, disposed in racemose spikes. 



1 T. GRANDIFLORA (Dougl. in bot. reg. t. 1178.) leaves cor- 

 date, lobed, dentately serrated ; racemes elongated ; petals ob- 

 long-linear, pinnatifidly jagged ; styles 2. Tf.. H. Native of 

 the north-west coast of America, in shady pine woods, near 

 springs along the shore. Mitella grandiflora, Pursh. fl. amer. 

 sept. 1. p. 314. This is a fine plant, with leaves as large as 

 those of Malva rotundifolia. Flowers reddish. Stem and pe- 

 tioles generally thickly clothed with fulvous hairs.

2 T. PARV1FLORA (Hook. fl. 



bor. amer. 1. p. 239. t. 78. A.) 

 plant scabrous from hairs ; leaves 

 ternate ; leaflets deeply pinnati- 

 fid; racemes short; petals un- 

 guiculate, trifid; styles 3. TJ.. 

 H. Native of North California. 

 Abundant in light gravelly soils, 

 under the shade of sappling pines, 

 near Fort Vancouver ; plentiful 

 in low hills at the grand rapids of 

 the Columbia ; and also at Spo- 

 kan river. Root small, rather 

 fusiform, more or less fibrous, 

 and bearing tubers ; tubers gran- 

 ular. Racemes terminal, curved. 

 Flowers middle-sized, red. This 

 is a curious and distinct plant, 



with something of the habit of slender specimens of Saxifraga 

 granulata. 



Small-flowered Tellima. PL 1 foot. 



Cult. See Mitella, p. 227. for culture and propagation. 



VII. DRUMMO'NDIA (named after Thomas Drummond, 

 who accompanied Capt. Franklin and Dr. Richardson in their 

 last journey in North America). D.C. prod. 4. p. 49. Mitella 

 species, Graham. 



LIN. SYST. Pentandria, Digynia. Calyx with an obconical 

 tube (f. 50. 6.), adhering to the capsule a considerable way : limb 

 5-cleft : lobes triangular, valvate in aestivation (f. 50. a.), and 

 at length reflexed. Petals 5, pectinately pinnatifid (f. 50. c.), 

 alternating with the calycine lobes. Stamens 5, in front of the 

 claws of the petals, nearly sessile. Stigmas 2, spreading, 2-lobed. 

 Capsule 1-celled, 2-valved at the apex, bursting long before the 

 seeds are mature (f. 50. d.). Seeds numerous, disposed along 

 2 opposite placentas. An herb, with a habit between Mitella 

 and Heuchera. It differs from Milella in the capsule adhering a 

 greater length to the calyx, in the stamens being 5, not 10, and 

 in the stigmas being spreading, not erect, arid 2-lobed, not en- 

 tire ; and from Heuchera in the calycine lobes being valvate, not 

 imbricate in aestivation.

 bot. mag. t. 2933. Radical leaves 

 on long petioles, cordate, bluntly 

 lobed. Scape leafless. Flowers
