1. B. occidentalis, Ton-. & Gray. Smootliisli, or with some rusty hairs, above 

 somewhat ylaiidul.U' : stem sleinler, a foot or two hi^li : leaves thiu-meiuhiaiiaceous, 

 3-7-lobeJ: petioles with slightly ililated base l'ringe<l with some rameiiLaceous 

 bristles : calyx-lobes lanceulatetiiau-'ular, very acute. — Fl. i. 577. S(ui/'ra</a 

 raauHCulijotut, Hook. l-'l. i. 241), t. HiJ, probably, but surely no l)ulblets in the axils 

 of the radical petioles. *S'. data, iS'utt. in Torr. & Gray, h\ i. 575, iu part or 

 wholly. 



Woods of tlie Coast Eanges, from Santa Barbara to Mendochio counties and north to "Wash- 

 ington Ti-rritory. Leaves 1 to 3 inches in diameter. Petals 2 or 3 lines long. 



2. B, major, Gray. Stouter ami larger, 2 or 3 feet high : leaves 4 to 8 inches 

 in diameter, 5 - U-clelt : petioles abruptly appendaged at base, the lower with i^cari- 

 ous, the upper with I'oliaceous and rounded nakeil stipules : calyx-lobes triangular.

Wooded region of the Sierra Nevada from Mariposa Co. northward {Bridijes, Brewer, Bulandcr), 

 and Oregon {E. Hall). As this extends to Oiegon it may possibly be Nuttall's Saxifraga data or 

 have been confounded witli it ; but llie "tufts of long chatfy hairs" at the base of the petiole 

 must rather refer to the preceding. The stipules in this are conspicuous, not bristly-appendaged, 

 the upper foliaceous, partly elasping or appressed to the stem, 4 or 5 lines long. 



B. ACONITIKOLIA, Nutt., of the Alleghany Jlountains, with more laciniate leaves, has some 

 ramentaceous bristles either in the a.\ils or fringing the slightly dilated base of the petiole. 



B. RicuARUSoNii, tjray, tlio Arctic species, has contracted thyrsoid intlorescence and no ramen- 

 taceous bristles on tiio dilated base or in llie a.\il of the ieuf-stalk. 



3. BOLANDRA, Gray. 

 Calyx broadly campanulate, 5-lobed ; the lobes triangular-lanceolate and acumi- 

 nate, valvate in the bud, recurved; the tube free from the ovary. Petals 5, inserted 

 on the throat of the calyx, small, very slender-subulate, recurved, persistent. Stamens 

 5, alternate with the petals, short: anthers 2-colled, cordate- 2-lobed. Ovary in- 

 cluded iu but wholly free from the dilated calyx, ovato with a broad 2-celled base, 

 deeply 2-(!h!l'l. ubovcv into two lupeiijig horns, each tip[)od by ii trunciitu nearly 

 sessile stigma. Capsule membranaceous, included in the calyx, early opening down 

 the inside of the horns or beaks. Seeds very numerous and minute, with a thin 

 rather loose coat. — A single species, with the foliage and habit of Boyhlnia or some 

 Saxifrages, the calyx of Tdllma, petals rather of Tolmiea, and perhaps the early 

 dehiscent fruit ofTiarella, but the beaks equal. — Proc. Am. Acad. vii. 3-11. 



1. B. Californica, Gray, 1. c. A span or two high, weak and ascending ai)par- 

 ently from a hliform rootstock, granulate- bulblet-bearing at the base of the stem, 

 glabrous or nearly so: leaves alternate, membranaceous; the lower round-renifurm, 

 about 5-lobe(l, on long and liliforni petioles (the base of which is sometimes dilated 

 and stipule-like) ; the upper sessile or clasping, merely incised or few-tootiied, 

 gradually reduced ui)ward to small ovato or lanceolate bracts, borne on or subtend- 

 ing the slendiu' ono-lloweretl somewhat pauicuhito peduncles : petals dull purpli.sh.

 which commemorates tlie signal services rendered liy the discoverer, Dr. H. N. Bolander, to ('ali- 

 fornian botany. Thus far it seems to have been collected only by Dr. Bolander and by the 

 founder of tbe genus. 



4. TOLMIEA, Torr. & Gray. 

 Calyx funnelform, free from the ovary, thin antl membranaceous, gibbous at base ; 

 the 5 short lobes somewhat unequal and imbricated in the bud ; the tube in age
