578 SCROPHULARIACE^. Orthocarpus. 



Plumas Co., Lemmon. Thence north to British Columbia. Corolla over half an inch long, 

 slightly or decidedly pubescent. 



O. ToLMiEi, Hook., is a smoothish and h)osely branching species of this section, with attenu- 

 ate and mostly entire leaves, flowers in short and at length loose spikes, and smooth yellow 

 corolla seldom half an inch long. It inhabits Utah and the interior of Oregon. 



0. PUKPUREO-ALBUS, Gray (Watson, Bot. King E.xp. 458), the only remaining species of this 

 section, is a native of New Mexico and Southern Utah. It is known by its attenuated and uniform 

 leaves, slender loose spike, and especially by the more exseited and slender tube of the (i)urple 

 and white) corolla, the galea also rather narrower ; so that it connects with the next section, 

 with some species of which it agi-ees in having the loose seed-coat coarsely reticulated, but not 

 costate nor with the areolations in longitudinal rows. 



§ 3. Lower lip of the corolla conspicuously ^-saccate, and very much larger than the 

 slender upper one; its teeth small or minute; the tube filiform or slender: 

 stigma capitate, sometimes '2-lobed : bracts all herbaceous and like the leaves, or 

 their tips somewhat coloi'ed in 0. gracilis and the last species. — Triphysaria, 

 Eeuth. {Triphysaria, Fischer & Meyer.) 



% Anthers one-celled : lower lip of corolla saccately 3-lohed from the end : seed-coat 

 close, conformed to the 1 - 2-apicidate nucleus. 



-i- Stamens soon free from the less involute oblong-lanceolate uppei' Up of the corolla. 



9. O. pusillus, Benth. Weak and diffuse, branched from the base, 2 to 6 

 inches high, somewhat hirsute: leaves 1 - 2-pinnatifid or floral ones 3-5-parted 

 into filiform or almost setaceous divisions, exceeding the scattered and inconspic- 

 uous flowers : corolla purplish, glabrous, 2 or 3 lines long ; tlie tube not exceeding 

 the calyx and little longer than the lips ; the upper lip considerably longer than 

 the moderately 3-lobed "lower one, a little surpassing the longer stamens : capsule 

 globular. — Scroph. Ind. 12, & DC. Prodr. x. 535. 



Low ground, around San Francisco Bay, and in Oregon. Lower lip rather open and with 

 beardless tliroat ; the sacs short. 



10. O. floribundus, Benth. 1. c. Slender and erect, a span to a foot high, 

 almost glul)rous, fastigiately branched : upper part of the leaves pinnately parted 

 into linear-filiform divisions, some of them incised : spike many-flowered, dense 

 above : bracts of the upper flowers not exceeding the calyx : stamens about the 

 length of the soon open upper lip of the corolla ; the lower lip with 3 diverging 

 oval sacs ; their scarious teeth lanceolate and erect. 



Hillsides, common around San Francisco Bay. Corolla white or cream-color, half an inch 

 long, glabrous or the tube slightly pubescent ; this twice the length of the calyx ; two longi- 

 tudinal villous lines on the inside of the lower lip corresponding to the sinuses between the sacs. 



-i- -{- Stamens more strictly enclosed in the acute involute-subidate upper lip : loiver 

 lip of 3 obovate or globular-inflated sacs, tomentose-pmherident xinderneath or gla- 

 brous, not more than a quarter of the length of the filiform and mostly densely 

 pubescent tube ; the two folds ivithin separating the sacs villous-bearded : floioers 

 numerous in a rather dense spiJce : upper bracts not exceeding the calyx ; the loiver 

 and the cauline leaves above the broader entire base pinnately parted into slender 

 setaceous or filiform divisions. 



11. O. erianthus, Benth. 1. c. Erect, fastigiately much branched from near the 

 base, soft-pubescent, a span or two high : corolla sulphur-color, with the very 

 slender and acute slightly falcate upper lip (and sometimes the throat) dark purple ; 

 the tube thrice the length of the calyx (half to two thirds of an inch long). 



Var. roseus, Avitli rose-colored corolla (or white turning rose-purple ? ) ; the tube 

 shorter. — Triphysaria versicolor, Fischer & Meyer, Ind. Sem. Petersb. ii. 521 



Moist grounds, common from Monterey Bay northward. The variety in sandy fields, Koyo, 

 Mendocino Co., Bolander. Fischer and ileyer describe their plant above cited (which must have 

 come from north of San Francisco) as having a white corolla clianging to rose-color, and the 

 tube twice the length of the calyx. The bcaid within the lower lip is denser in this than in tlie 

 next.
