POLEMONIUM 



POLEMONIUM 



Polemoniums are easily raised from fall-sown seed. Also 

 propagated by division. They are said to be impatient 

 of soil on the leaves.

A. Corolla tubular or funnelform, the tube longer than 

 the lobes. 



1. paucifldrum, Wats. Perennial, erect and branched, 

 somewhat villous, 1-2 ft. : Ifts. 8-13 pairs, about 1 in. 

 long: fls. yellowish, tubular, the tube 1-1 % in. long, 

 much longer than the lobes, solitary or loosely corym- 

 bose, long-pedunculate; stamens bearded at base, about 

 equaling the corolla: caps, oblong. Mex. The color is 

 said to be a good clear yellow, tinged red outside. 

 Offered by J. W. Manning in 1892, but subsequently 

 dropped. 



2. confertum, Gray. Perennial, with a thick woody 

 rhizome, sticky, smelling of musk, 9-18 in. high: Ifts. 

 very small and so crowded as to seem whorled: infl. 

 a dense head; fls. honey-scented, deep blue, %-l in. 

 long; corolla narrowly funnel-shaped; filaments naked 

 or nearly so and not dilated at base. Rockies and 

 Sierras. Gn. 10:506. G.C. II. 24: 12; III. 27:237. G.M. 

 55:459. G.W. 7, p. 356. Intermediate between Pole- 

 monium and Gilia. 



3. mellitum, A. Nels. (P. confertum var. meWdum, 

 Gray). An attractive species with white or pale fls., the 



3091. Polemonium reptans. The leaflets are 

 often much broader. ( X M) 



plant usually taller than P. confertum and the infl. more 

 lax and leafy and becoming racemose or spike-like: 

 corolla fully 1 in. long, the lobes only one-third or one- 

 fourth the length of the tube: herbage heavily musk- 

 scented, fls. honey-scented (whence the name). Rocky 

 Mts. Nev. Gn.W. 25:557. 



AA. Corolla campanulate to rotate, the tube mostly shorter 



than the lobes. 



B. Plants low, with thickened rootstocks: Ifts. seldom y^in. 

 long. 



4. humile, Willd. (P. Richardsonii, Graham). Low, 

 slender plant from somewhat creeping rootstocks, 

 about 9 in. high: Ifts. 15-21, 2-6 lines long: fls. bell- 

 shaped, blue or purplish. July, Aug. Arctic regions. 

 B.M. 2800 (yellow eye). G.C. II. 19:793. B.R. 1303 

 (as P. cserulewn var. piliferum). It has the odor of 

 ripened grapes. Brand combines this plant with P. 

 lanatum, Pallas, of the Arctic Zone and the Altai re- 

 gion, making this form P. lanatum var. humile, Brand, 

 with a wide range in the high N. P. Richardsonii, 

 referred here, was raised from seeds collected at Great 

 Bear Lake. The plant cult, as P. Richardsonii grows 

 about 18 in. high, and bears profusely of bright blue 

 fls. (varying to white in var. dloum, Hort.); probably 

 the best of the genus, and in need of botanical study. 

 Aside from references above, portraits occur in Gn. 

 78, p. 615; G.M. 45:494; Gn.W. 5:757; J.H. III. 

 54:101. 



Var. pulchellum, Gray (P. pulchellum, Bunge. P. 

 lanatum var. pulchellum, Brand). Differs in having 

 smaller fls. ranging from violet and lavender to nearly 

 white and in the viscid pubescence, which is minute. 

 Arctic coast and southward according to Gray, but 

 restricted by Brand to Asia (Altai region). 



5. pulcherrimum, Hook. (P. pumilum var. pulchel- 

 lum, Rydb.). By Gray considered to be a more viscid 

 lax or diffuse and small-fld. form of P. humile var. 

 pulchellum, the corolla violet varying to white, and with 

 narrower lobes. By Brand it is made to comprise the 

 American forms passing as P. humile var. pulchellum, 

 with much smaller fls.: sts. erect, more or less pilose 

 and glandular- viscid, 10 or 12 in. or less high: radical 

 Ivs. numerous, the Ifts. 17-27, small, ovate, obtuse and 

 entire; st.-lvs. few: fls. in terminal corymbs, the corolla 

 very variable, usually bicolored (blue with white tube), 

 5-8 lines long, the lobes oblong and much exceeding the 

 short tube: caps, ovoid, much shorter than the calyx. 

 High Rocky Mts. and northward. B.M. 2979. B.R. 

 1304 (as P. humile}. Gt. 9 : 292 (as P. pulchellum). 



BB. Plants weak and rather low, with a short rootstock: 

 Ifts. y^-1 y?, in. long. 



6. reptans, Linn. GREEK VALERIAN. Fig; 3091. 

 Height 1 ft. or less: slender, weak and diffuse but never 

 creeping (as the name would indicate): foliage not 

 viscid or glandular; Ifts. 5-15, from lance-oblong to 

 broad-ovate, acute, entire: fls. light blue, %in. across, 

 in a loose panicle-like cluster terminating the st.; 

 corolla J^-^in. long in cult., about ^4in. or more broad; 

 calyx-lobes acute or obtuse; stamens not exserted: caps, 

 about 3-seeded. Open woods, N. Y. to Ala., west to 

 Minn, and Kans. April, May. B.M. 1887. Said to 

 be an easy prey to snails, especially in winter, when they 

 attack the rootstocks. 



7. carneum, Gray. St. lax or loosely branching, 1-2 

 ft. high, with a horizontal rootstock: Ifts. 5-17, often 

 1^2 in- long) ovate to oblong-lanceolate: fls. salmon or 

 flesh-color fading to purplish, 1-1% m - across, the 

 corolla-lobes rounded-obovate; calyx deeply 5-cleft, 

 with ovate-oblong lobes. Mountain woods, Calif., 

 Ore. G.C. III. 48 : 134. Offered in Ore., 1892, but 

 probably not in cult. now. Closely allied to P. reptans. 



BBB. Plants strong and erect, mostly tall, with slender 



rootstocks or roots: Ifts. usually large. 



c. Fls. not blue (seldom running to violet), yellowish, 



cream-color or salmon. 



8. foliosissimum, Gray. Sts. solitary and erect, 1-3 

 ft. tall, simple or branched, hairy at base and viscid 

 above, from a woody short rootstock: herbage strong- 

 scented; Ivs. many; Ifts. lanceolate to ovate-lanceo-
