^L. hirtum, Lehm., 1. o. Hispid or hirsute, and at length rough, a foot or two Jiigh: 

 leaves lanceolate or the lower linear and floral ovate-oblong: corolla bright orange, with 

 ample and rotate deeply 5-clef t limb and prominent crests in the throat ; the ring at 

 base witliin bearing 10 very hirsute lobes or teeth : flowers mostly pedicelled and linear- 

 lanceolate : calyx-lobes elongated. — Batschia VaroUnensis, Gmel. ^yst. i. olo. B. Gnielini,

 ii. 225. L. Bejariense, DC. 1. c. 79. — Pine barrens, &c., Jlichigan to ilinnesota, Virginia, 

 Florida, Texas, and Colorado. — Tube of the intense orange corolla 4 or 5 lines long, the 

 outspread limb sometimes almost an inch in diameter, but often half smaller. In some 

 specimens, the stamens are inserted on the middle of the cor(jlla and the style rises to 

 the throat ; in others, the style rises only to the middle and the stamens are in the throat. 



* * * Corolla bright yellow, salvL'rform; its tube in well-developed tlowers 2 to 4 times the length 

 of the calvx ; the crests in the throat conspicuous and arching; the lobes undulate and more or less 

 erose: later flowers cleistogenous. — Fentahphus, A. DC. 



^ L. angustif olium, Michx. Erect or diffusely branched from the base, a span to a foot 

 or more high, minutely scabrous-strigose and somewhat cinereous : leaves all linear : 

 flowers pedicelled, leafy-bracted, of two sorts ; the earlier and conspicuous kind with tube 

 of the corolla an inch or less in length and the rounded lobes commonly crenulate-erose; 

 later ones, and those of more diffusely branching plants, with inconspicuous or f^mall and 

 pale corolla, without crests in the throat, probably cleistogenous, the style shorter than the 

 nutlets ; in these the pedicels are commonly recurved in fruit : nutlets usually copiously 

 impressed-punctate, conspicuously carinate ventrally. — ilichx. Fl. 1. 130 (the state with 

 inconspicuous flowers) ; Bebb in Am. Naturalist, vii. 091. L. linearifhUum, Goldie in Edinb. 

 Phil. Jour. 1822, .jl9, the same state (unless possibly Goldie's plant is L. arcense). L. brevi- 

 Jiorum, Engelm. & Gray, PI. Lindh. i. 44, a similar state. Long-flowered plant is Balsclua 

 longlflora (Pursh, Fl. i. 132), & B. decumbens, Xutt. Gren. i. 114. Litliospermum longiflorum, 

 Spreng. L. incisum, Lehm. 1. c. ; Hook. Fl. ii. t. lO-j. L. ilandanense, Spreng. ; Hook. 1. c. 

 t. 166, a small and smaller-flowered form. Pentalophus lonr/ijlorus & P. ilandanensis, A. DC. 

 Prodr. X. 87. — Dry and sterile or sandy soil, prairies and banks of streams, Illinois and 

 Wisconsin to Saskatchewan and Dakota, south to Texas, and west to Utah and Arizona. 

 Boot thick and deep, abounding in violet-colored dye. Glandular ring at base of corolla 

 naked. In the state with large and showy flowers, as far as known, the stamens are 

 alwa3-s borne at the upper part of the tube, and the filiform style is slightly exserted : 

 but perhaps there is some heterogone-dimorphism. There are seemingh' all stages 

 between these conspicuous and the cleistogenous blossoms which are produced through 

 the season. 



18. ONOSMODIUM, Miclix. ("Oroa/ia, and ilSog, likeness, from the re- 

 semblance to the Old- World genus Onosma.) — Perennials (of the Atlantic States 

 and Mexico, &c.), rather stout and coarse, rough-hispid or hirsute ; with nervose 

 or costate-veined leaves, and leafy-bracteate flowers crowded in scorpioid spikes 

 or racemes, when fruiting more separated; the bracts resembling the leaves. 

 Fl. spring and summer, strongly proterogynous, the style early exserted. Corolla 

 greenish-white or yellowish-green: a glandular 10-lobed ring adnate to the base 

 of the tube within. Xutlets as in most Lithosperma. — ]\Iichx. Fl. i. 132. 

 Otiosmodium and Jfucromeria in part, Don ; DC. Prodr. x. 68 ; Benth. & Hook. 

 Gen. ii. 859. True Macromeria (exserta) has versatile anthers on capillary and 

 long exserted filaments. 



§ 1. MACROMERioiDEi?. Corolla 3 or 4 times the length of the calyx, narrow ; 

 the sinuses plane : filaments slender, longer than the linear-oblong obtuse anthers. 

 — Jlacromeria, Don, & DC. partly. (One or two Mexican species have the 

 anthers promptly versatOe or transverse ; in ours they remain erect.) 



O. TTlurberi. Somewhat sparsely strigose-hispid with short bristles (at least on the 

 foliage) and minutely appressed-pubescent or when young canescent : stem simple, 2 or 3 

 feet high : leaves pinnately 5-7 -ribbed ; the cauline oblong-lanceolate or oblong (4 or 5
