14. C. SESSiLii'LOUA, Pursh. Calyx and corolla with a narrow elongated tube ; lip 3-parted, the lobes 

 linear-lanceolate ; corolla 2' long, galea 4-G" in length.— Wisconsin and Illinois, west to the plains and 

 sonthi to Louisiana, New Mexico, and Chilmahna. 



15. C. BREVIFLORA, Gray. A span high ; spikes dense, scarcely 1' long in flower ; calyx ovoid-oblong,

ORTHOCARPUS. 



Based upon an examination of the specimenriu the Herbariums of Dr. Gray, Dr. Torrey, and Prof. 

 Eaton, and a large recent collection made in California by Messrs. Kellogg and Haniford. 



§ 1. Triphysaria, Benth. Lip of the corolla 3-saooate, the teeth or appendages shorter than the 

 sacs. 



' Anthers 1-celled. 



1. O. PUSttLUS, Benth. &-10' high, slender, much branched, more or less hirsute ; leaves setaceously 

 multifid, mostly i' long, or less ; spike interrupted ; bracts exceeding the flowers, liuear-lobed ; calyx- 

 teeth linear, exceeding the tube, about equaling the (2J-" long) yellowish glabrous corolla ; sacs very 

 small and teeth nearly obsolete, galea uncinate ; the lower anthers smaller, abortive ; capsule subglobose, 

 2" or less in length. — About San Francisco Bay ; Oregon, (Wilkes.) 



2. O. FLORLBUNDUS, Benth. 3-15' high, stouter, subglabrous, branched ; leaves 1-2' long, linear- 

 lanceolate, setaceously multifid at the apex ; spikes dense ; bracts shorter than the flowers, lobes linear, 

 entire; calyx 3" long, teeth broad, acute, shorter than the tube; corolla yellow, glabrous, 5-6" long, the 

 sacs li-2" broad, galea straight, obtusish ; stamens exserted, often nearly equal ; capsule 2" long, oblong. — ■ 

 About San Francisco Bay. 



3. 0. ERIANTHUS, Benth. 2-10' high, usually corymbosely much branched, puberulent ; leaves as in 

 the last, 1-3' long ; spikes rather loose; lobes of the bracts linear-laoiniate, often entire; calyx 3-4" long 

 often purplish, the ovate or lanceolate teeth shorter than the tube ; corolla 8-12" long, white, pink or 

 yellowish, tube pubescent, sacs 2J" in diameter, glabrous with the folds often bearded within, the galea 

 purple, subulate, straight, rigidly erect ; capsule ovate, 3-4" long. — California, from San Diego to Sacra- 

 mento Eiver. 



4. O. FAUCIBARBATUS, Gray. Pac. B. li. Sarv. 4. 121. Resembling the last, but rather stouter and 

 glabrous, 6-16' high and branching unequally along the stem ; leaves usually broader ; corolla more 

 usually yellow or yellowish, the sacs rather smaller, puberulent with the folds always bearded, the galea 

 less purple. — California, from San Francisco to the Klamath River. 



* * Anthers 2-celled. 



5. O. LACERUS, Benth. Plant. Hartw. 329. 6-10' high, branched, hirsute-pubescent or below glabrate ; 

 leaves 1-2' long, linear or narrow-lanceolate, linear-lobed ; spikes short, dense ; bracts with entire linear 

 jobes ; calyx 4" long, the linear or lanceolate lobes equaling the tube ; corolla rose-colored, 8-10" long, 

 nearly as in 0. eiianthus but the tube subglabrous and the lip puberulent.— California, from San Luis 

 Obispo to the Sacramento Valley. 



6. O. CAMPESTKis, Benth. Plant Sartw. 3-29. 2-4' high, simple or somewhat branched; leaves 1' 

 long, mostly entire ; spikes few-flowered ; calyx pilose with spreading white hairs ; lower anther-cell 

 minute ; otherwise as in the last of which it is probably only a depauperate form.— Collected in the 

 lower Sacramento Valley by Fremont, Hartweg, and Rich. 



7. O. GRACILIS, Benth. Subpubescent ; stems very slender, 4-8' high, simple or branched ; leaves 

 linear, lobed at the apex, i-1' long ; spike interrupted below ; bracts small, scarcely equaling the calyx ; 

 calyx 3" long, purplish, the lanceolate teeth shorter than the tube ; corolla 5-6" long, purplish, pubes- 

 cent, the straight subulate galea nearly twice longer than the lip, the teeth erect and lanceolate ; capsule 

 2" long, oblong.— Collected in California by Douglas. Specimens from Kellogg and Haniford, probably 

 the same, are more pilose, the corolla yellow, and the calyx green with narrow teeth. 



8. O. LITHOSPERMOIDES, Benth. Stout and strict, 4'-2° high, hirsute-pubescent throughout, simple 

 or branched ; leaves 1-2' long, lanceolate or ovate, 3-nerved, coarsely lobed at the apex or the lower 

 entire ; spike dense, 1-8' long, the broad palmately lobed bracts equaling the corolla-tube ; calyx 

 6" long, the linear-lanceolate teeth nearly as long as the tube; corolla 8-12" long, yellow, puberulent, the
