Boykinia. SAXIFRAGACE-E. I95 



In the high Sierra Nevada, at 8,000 to 10,000 feet, from Mt. Dana to Sierra Co., Brewer, Bo- 

 lander, Torrey, Lemmon. 



S. LEtTCANTHEMlFOLlA, Michx., or an ambiguous form between it and S. stellaris, Linn, (agem- 

 miparous state of which occurs in the Rocky .Mountains and northward), is found from Wash- 

 ington Territory to Alaska. It has larger and toothed or incised leaves, narrow and dissimilar 

 petals, evident styles, and is generally a much larger plant. 



* * Leaves rounded and cordate on long naked petioles : filaments broadened up- 

 ward, spatulate, sometimes almost petaloid: calyx free from the 2-cleft ovary and 

 capsule, soon reflexed : petals obovate or at length oblong, obtuse, on. a short claw : 

 scape paniculately and loosely man y flowered : pedicels filiform. 



7. S. Mertensiana, Bongard. Scape and leaves from a scaly granulate bulb, 

 more or less glandular-pubescent : base of petioles dilated into thin scarious bud- 

 scales : leaves crenately or incisely many-lobedj the lobes often 3-toothed at the 

 end : panicle effuse ; the branches mostly flowering only at the apex and bearing 

 granulate bulblets down the sides: filaments sometimes 12 or more, occasionally 

 sterile and petaloid: capsule inflated-ovate. — Veg. Sitcha, 141. S. hrtrrauthn, 

 Hook. Fl. i. 252, t. 78. S. aestivalis, var. (heterantJia), Torr. & Gray, FL i. 568. 



W led banks in the Coast Ranges, from Sonoma Co. northward, extending to Alaska. Well 



marked by the stout and bulb-like caudex, producing bulblets, and usually by the clusters of 

 little granulate bulblets on the slender branches of the panicle. Leaves 2 to 4 inches in diameter. 

 I'etals about 2 lines long. 



8. S. punctata, Linn. Scape and leaves from a short creeping rootstock, 

 glabrous 01 somewhat pubescent: leaves reniforrn to round-cordate, of rather firm 

 texture, coarsely and almost equally many-toothed or somewhat incised: petioles 

 hardly dilated except at the insertion : panicle usually narrow, not bulblet-beariug : 

 capsule oblong. — S. aestivalis, Fischer, &c. 



Sierra Nevada at 8,000 feet and over (Torrey, Lemmmi), and on the mountains eastward to 

 Colorado: northward to Pickling Straits, and in X. Asia. Leaves 1 to 3 inches in diameter. 

 Scape a span to 2 feet high. Petals about 2 lines long. 



§ 4. Leafy stems short, cespitose, and thickly beset with the small evergreen sessile 

 leaves: scape-like peduncle few-flowered ; calyx 5-parted, nearly free. 



0. S. Tolmiei, Torr. & Gray. Forming depressed tufts, glabrous or nearly so : 

 leaves much crowded, spatulate, coriaceous, nerveless, or with obscure midrib, with 

 revolute entire margins (3 to 5 lines long) : peduncles 2 inches long, cyniosely 1-6- 

 ftowered : petals lanceolate, white, about twice the length of the ovate obtuse 

 spreading calyx-lobes: filaments dilated at the summit: carpels (often .'! or 4) in 

 frail very obtuse and large, united only at the base. 



High Sierra Nevada, at 9, feel and upward (2! Ifttir, I.- • I; also northward 



in the Cascade .Mountains to Washington Torritory. Flowers only 2 lines long: fruit :j or 1 

 lines long. 



2. BOYKINIA, Nutt. 

 Calyx 5-lobedj the lobes valvate but early open in the bud: the tube at length 

 globular or ovate, adherent to the ovary. ' Petals 5, entire (varying from imbricate 

 to convolute in the bud), the base contracted into a short claw, deciduous, stamens 

 5, short, alternate -with the petals: anthers 2-celled. Ovary and capsule 2-celled, 

 dehiscent dmvn the stylilernus Leaks. Seials small ami very numerous, ovoid, with 

 a close somewhat crustai !. very minutely and evenly papillose, Peren- 



nial berbs (X. American); with creeping rootstocks) leafy simple stems, and panicu- 

 lati or corymbose cymes of white flowers; the leaves all alternate, round-renifonn, 

 palm'ately lobed and incised or toothed, the teeth with callous-glandular tips, ami 

 the petiole mostly with stipule-like dilations or appendages al base,
