578 SCROrilULARlACEJ!;. Orlhumr^ju.i. 



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

 slightly or decidedly pubescent. 



0. ToLMiEi, Hook., is a .snioothish and loosely branching species of this section, with attenu- 

 ate and mostly entire lisivcs, Howcrs in short and at Icnglli loose spikes, and smooth yellow 

 corolla seldom hall' an incli long. It inhabits Utah and tlie interior of Oregon. 



0. I'liuruuKO-Ai-uii.s, dray (Watson, iJot. King' Kxp. 4r>8), the only remaining sjieeics of this 

 section, is a native of New iMe.Kico and S(jutlieni Utah. It is known by its attenuated and uniform 

 leaves, slender loose spike, and especially by tiie more exserted and slender tube of the (pui [.lo 

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

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

 eostate nor with the areolations in longitudinal rows. 



§ 3. Lower lip of the corolla conspicuously 3-saccate, and vei'y much larger than the 

 slendtr ii/iper one; its teeth small or mi mite ; the tuhe Jili/orni or slender: 

 stiyma capitate, suinetimcs 'l-lobed : bracts (dl herbaceous and like the leaves, or 

 their tips somewhat colored in 0. yracilis and the last species. — Tuu'iiYSAmA, 

 lientlj. {Triphysaria, I'iscliei' & Meyer.) 



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

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

IJ. O. pusillus, lii'iith. Weak and diU'iiso, Imiiiclied irom tlio base, 2 to (i 

 incliea liigli, suiiiewhat hirsute: leaves 1 - 2-i>iiiiiatilid or lloml ones 3-f)-purted 

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

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

 the calyx and little longer than the ]ii»s; the ujiper lip considerably lunger 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 und with 

 beardless throat ; the sacs short. 



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

 almost glabrous, iastigiately branched : upper part of the leaves jiinnately i)avted 

 into linear-lililorm divisions, some of them incisetl : spike many-Uowercd. 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 lipt with 3 diverging 

 oval sacs ; their scarious teeth lanceijlato and erect. 



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

 long, glabrous or the tulie .slightly jiubcscent ; this twice the length of the calyx ; two longi- 

 tuilimil villous lines on the inside of the lower lip corresponding to the sinusea between the sacs. 



"t- -»- Stamens more strictly enclosed iu the acute involute-subulate upper lij) : lower 

 lip of 3 obovate or ylobular-injlated sacs, tomentose-puberulent underneath or gla- 

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

 pubescent tube; the tivo folds ivithin separating the sacs villous-bearded : jloivers 

 numerous in a rather dense spihe : upper bracts not exceeding the calyx ; the lower 

 and tite cauline leaves above the broader entire base pinnateiy parted into slender 

 setaceous or jiliform divisions. 



1 1. O. erianthus, iHUith. 1. c. Erect, fastigiately nuich branched from near the 

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

 slender and acute slightly falcate up])er lip (and sometimes the throat) dark purple; 

 the tube tbi'icc the Icngtii of the calyx (half to two thirds of an inch long). 



Var. roseus, with rose-colored corolla (or white turning rose-purple % ) ; tin; tube 

 shorter. — TripJiysaria versicolor, Fischer & Meyer, Ind. Seni. I'etersb. ii. 52? 



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

 Mendocino Co., Bohuulcr. Fischer and Meyer describe their plant above cited (which must have 

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

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