516 HYDROPHYLLACE^. Romanzoffia. 



oblong, short-petiolecl or sessile : pedicels recurved in fruit : the enlarged heart- 

 shaped sepals much longer than the ovate pointed 8-seeded capsule : stamens and 

 style included. 



Truckee Pass, &c., Nevada, Watson. Probably extending totlie California line. 



9. ROMANZOFFIA, Cham. 

 Calyx deeply 5-parted, the lobes similar. Corolla more or less funnelform, not 

 appendaged within, deciduous. Stamens inserted on the base of the tube of the 

 corolla, unequal. Style undivided, filiform : stigma small, entire. Ovary and the 

 retuse capsule 2-ceUed or nearly so. Ovules and pitted-reticulated seeds numerous, 

 on narrow-linear placentae. — Low and delicate perennial herbs, with the aspect of 

 Saxifrages : the leaves mainly radical, all alternate, round-cordate or reniform, cre- 

 nately 7 - 11-lobed, long-petioled : the scapes or flowering stems racemosely or pa- 

 niculately and loosely several-flowered. Corolla pink or purple, varying to white, 

 delicately veiny. 



A genus of two species, the original one, R. Unalascltlccnsis of Chaniisso, found only on Una- 

 laska and adjacent islands. 



1. R. Sitchensis, Bongard. Slender filiform rootstocks bearing small grain-like 

 tubers : scapes weak, a span long : pedicels spreading and longer than the flowers : 

 calyx-lobes glabrous, oblong-linear or lanceolate, much shorter than the corolla, 

 a little shorter than the capsule : style long and slender. — Veg. Sitka, 41, t. 4 : 

 Hook. f. Bot. Mag. t. 6109. 



In shady woods along the Coast Eange, especially in redwoods, from Santa Cruz northward ; 

 extending to Alaska. 



10. HESPEROCHIRON, S. Watson. 



Calyx 5-parted, rarely 6 - 7-parted, and the lanceolate or linear lobes sometimes 

 unequal. Corolla campanulate or rotate, 5-cleft, rarely 6 - 7-cleft, deciduous. Sta- 

 mens inserted on the base of the tube of the corolla, unequal, included : filaments 

 subulate. Ovary partly one-celled, tapering into a short style, which is barely 

 2-cleft at the tip : stigmas minute. Ovules numerous, on dilated placentae, borne 

 on incomplete semi-dissepiments. Capsule loculicidal, 15- 20-seeded. — Dwarf 

 and stemless perennials or possibly biennials, soft-pubescent ; with spatulate or 

 oblong entire leaves on margined petioles, and from their axils naked one-flowered 

 scapes, of about the same length, bearing a solitary purijlish or nearly white flower. 

 Base of the calyx obscurely adnate to the broad base of the conical-ovate ovary : 

 seeds rather large, and with a somewhat fleshy minutely reticulated coat. — Bot. 

 King Exp. 281, t. 30 ; Gray, 1. c. 330. 



An anomalous genus, but probably of this order, peculiar to California, Oregon, and the adja- 

 cent interior region. Only one species has been found in California, and it is doubtful if the 

 second is distinct. 



1. H. Calif ornicus, ^Vatson, 1. c. Leaves copious in a rosulate tuft (an inch 

 or two ]i)ng, besides the petiole into which the lilade abruptly contracts or gradually 

 tapers) : corolla oblong-campanulate ; its lobes shorter than the tube. — Ourisia 

 Calif ornica, Benth. PL Hartw. 327. H. latifolius, Kellogg in Proc. Calif. Acad. 

 V. 44, a large state. 



Hills and meadows of the Sierra Nevada, from the Yosemite northward to "Washington Territory, 

 and east to Nevada and Utah. Corolla from 5 to 8 or 9 lines long : the lobes oblong.
