petioles stipularly dilated at base. Calyx 5-lobed; lobes valvate, but 

 early open in the bud; the tube more or less adherent to the ovary. 

 Petals 5, entire, imbricate or convolute in bud. Stamens 5, short, alternate 

 with the petals. Capsule 2-celled, dehiscent down the beaks. Seeds 

 minutely granulate or papillose. 



1. T, elatum, (Nutt.). Slender, 12 ft, high, glabrous or glandular- 

 pubescent, the bases of the petioles bearing brown bristly hairs : leaves 

 thin-membranaceous, 5 7-lobed, 13 in. broad: calyx-lobes lanceolate- 

 triangular; tube oval and urceolate in fruit: petals cuneate-oblong, 

 obtuse, persistent, in age recurved: seeds elongated- oblong, acute at one 

 end, dark brown, rather densely tuberculate. Shady banks and rocky 

 margins of streams. May August. 



3. TELLIMA, Robert Brown. Perennial herbs, with leaves chiefly 

 radical, round-cordate, toothed or palmately divided, their petioles 

 stipulaceously dilated at base. Flowers in a simple terminal raceme. 

 Calyx campanulate or turbinate, 5-lobed, free from the ovary, or adherent 

 to it at base or even to above the middle; the short triangular lobes 

 valvate in bud. Petals 5, laciniate-pinnatifid, or 3 7-lobed, or entire, 

 distant, sometimes involute in bud. Stamens 10, short, included. Ovary 

 short, 1-celled, with 2 or 3 parietal placentae; styles 2 or 3, very short; 

 stigmas capitate. Capsule conical, opening between the short beaks. 

 Seeds very numerous, with a close coat. 



* Corolla regular , the petals greenish, sessile by a broad base, laciniately 



pinnatifid; styles and placentae 2. 



1. T. grandiilora (Pursh). Dougl. Stoutish, 12 ft. high, from 

 rather coarse-tufted rootstocks; herbage rough-hirsute: leaves round- 

 cordate, more or less lobed, 24 in. broad: calyx ^ ^ in. long, inflated- 

 campanulate: petals deeply tinged with red: seeds light brown, oval, 

 strongly rugose-pitted. Wooded hills, or sometimes in open ground, 

 from Santa Cruz northward. May, June. 



* * Corolla slightly irregular, the petals while or pinkish, entire or lobed 



or toothed, short-unguiculate; styles and placentas 3. 



H Calyx turbinate, the tube more or less adherent to the ovary. 



2. T. affinis (Gray), Boland. Stems one or several from a slender 

 horizontal or ascending tuberiferous rootstock, commonly % ft. high, 

 scabrous-hirsute: radical leaves very few, round- reniform, slightly lobed. 

 1 in. broad; cauline relatively broader, 3-lobed to the middle, the lobes 

 coarsely toothed: calyx 2^ lines long; pedicels rather longer: lower 

 petals 4 or 5 lines long, 3-toothed, the upper narrower and a trifle shorter,
