^^^ LOHKLIACI'LK. Lunrentia. 



creeping small herbs, resembling Lobelias, with axillary blue flowers. — lienth. & 

 Hook. Geu. PI. ii. 549. 



I. L. carnosula, Ikutb. A glabrous diffusely branched or spreading annual, 

 somewliat succulent, 2 to 5 inc.lios iiigh : leaves sessile, oblong-linear or lanceolate, 

 entire, a cpuuter to half an inch long : peduncles lilifonn, even the lower inu(;h 

 longer than the leaves, the upper becoming corymbose or racemose : lobes of the 

 calyx linear, foliaceous, alK)Ut the length of the obconical tube and fully eipialling 

 that of the corolla : larger lip of the latter deeply 3-cleft into roundish-obovate lobes, 

 bright blue, with the 2-ridged palate yellow or whitish ; the smaller lip of 2 lanceo- 

 late lobes. — Lobelia carnosula, Hook. & Arn. Bot. lieechey, 3G2, where the undi- 

 vided corolla-tube is unnoticed. Porterella camulosa (by nusspelling), Torr. in Cat. 

 ri. Hayden Kep. 1872, 488; Parry in Am. Nat. viii. 177. 



Low and niiulJy places, in Sierra and Indian Valleys (Levwiun) ; thence noitheastwaid to Wyo- 

 ming Territory. A pretty little plant, in asp(;ct and llower resenililing the next genus, and the 

 corolla in vigorous specimens not much smaller ; known at once by the short and broad caj)sule 

 opening at the top. The late Dr. Torrey dedicated it to Prof. Thomas C. Porter, one of the 

 authors of the Flora of Colorado Territory ; but it proves to belong to a very old genus, chiefly 

 of the Mediterranean region and Southern Africa. 



2. DOWNINGIA, Torr. 



Calyx-tubo ami adnate ovary very long and slender, stalk-like, 3-8iilod, usually 

 twisted ; its limb divided down to the ovary into 5 lanceolate or linear foliaceous 

 lobes. Corolla with a very short but entire tube, and a bilabiate limb ; the smaller 

 lip of two narrow recurved or spreailing divisions, the other very broad and 3-lobed. 

 Filaments and anthers both united into a somewhat curved tube : two of the latter 

 bristle-tipped. Capsule very long and slender, early becoming 1 -celled, with two 

 parietal tiliform placentte, remaining closed at the apex, but the sides dehiscent by 

 two or three long fissures. Seeds as in the foregoing genus. — Low and spreading 

 glabrous annuals (of Oregon aiul California, and a third, species in Chili), rather 

 succulent or tender; Avith sessile and narrow entire leaves, the upper ones reduced 

 to bracts, and axillary sessile ilowers ; the corolla deep blue with a white or yellow- 

 ish centre. — Torr. in Pacif. K. Eep. iv. IIG; Benth. & Hook. 1. c. Clintotiia, 

 Hough, not of Paf. 



Under tlie name of Clinliuiia our two species have (U)nio into cultivation as ornamental annuals, 

 hut are riitlier dilliriill to miniiige. A mnv nmiie liein^ reiiuired, Dr. Torruy dedicaled tlio ^cuiim 

 to the nienioiy of his friend, tliu late Andrew Jackson Downing, of New York, wiu)se treatise 

 upon kndscaiie ganlening ami other horticultural and arboiicullural writings are still of sterling 

 value. 



1. D. elegans, Torr. Leaves acute, varying from ovate to lanceolate : smaller 

 lip of the corolla of two lancetdate divisions, the broad lip moderately 3-lobed, its 

 centre a broad white spot. — Cliutonia elegans, Lindl. Bot. Beg. t. 1241. 



Northern part of (California, and through Oregon. C. mnjmbosa, A. T)('. Prodr. vii. 347, is a 

 stouter and more leafy-stemmed variety, the ovary little longer than the subtending leaf. Ordi- 

 narily the slender and stalk-like ovary or capsule is over an inch in length, and the upper lloral 

 leaves so small that the inllorescenco is like a raceme. 



2. D. pulchella, Torr. Very like the foregoing, but the leaves mostly nar- 

 rower and obtuse : the two diviwiijus of the smaller lip ovute-lanceolate or oblouf^, 

 the larger lip nuich dilated and deeply 3-lobed, intensely uzure-blue with a large 

 white or yellowish centre. — Clintonia pulchella, Lindl. Bot. Beg. t. 1909; Sweet, 

 Brit. Fl Card. ser. 2, t. 412. 



Valley of the Sacramento to Oregon and Nevada. Plant 3 to (J inches high, rather more fleshy, 

 weak. Both species inhabit moist or wet places.
