REHMANNIA 



REINWARDTIA 



Var. tricolor, Hort. Fls. at first bright purple, later 

 almost violet-rose, the upper lip shaded with vermilion 

 and the throat whitish, spotted with purple. China. 



Brisccei, Hort. (R. elata xR. Henryi). Intermediate 

 in most characters, dwarfer than the former in hav- 

 ing an erect infl. instead of a condensed one: the fls. 

 are intermediate in color and of a soft pink: the Ivs. 

 arranged in a rosette are similar in shape to those of R. 



3359. Rehmannia elata. ( X K) 



Henryi and have the same dark veinings, while they 

 are much more velvety-hairy than those of R. elata 

 but less so than those of R. Henryi. A garden hybrid.

 each side, lobes acute, entire; bracts or flowering Ivs. 

 long-cuneate at base : corolla slightly larger than R. angu- 

 lata, bright rosy purple on the lips and yellow dotted 

 red in the throat. China. B.M. 8177 (as R. angulata). 



glutindsa, Libosch. (R. chinensis, Fisch. & Mey.). 

 Plant pubescent-hirsute: st. 6-12 in. high, erect and 

 weak: Ivs. alternate, obovate, attenuate to a short

 Perennial herb, 6-18 in. high, glandular-hairy: lowest 



Ivs. 3-7 in. long, elliptic-oblong, obtuse, base narrowed 

 to the petiole, crenately toothed, or more or less pin- 

 nately lobed and obtusely dentate: fls. axillary; calyx 

 ascending, never nodding, campanulate, lobes spreading, 

 deltoid or deltoid-ovate, obtuse; corolla-tube l%-2 

 in. long, pubescent outside, dirty yellow spotted red, 

 limb oblique, 2-lipped, white and pubescent, yellow, 

 red-dotted at the throat, upper lip 2-lobed, lower 3- 

 lobed, all the lobes rounded; ovary ovoid, glabrous.

kewensis, Hort. (R. Henryi x R. glutindsa). Sts. 

 leafy, about 2 ft. high: Ivs. petioled, ovate, glossy 

 green, irregularly dentate: fls. 2 in. long, 1J/2 m - across, 

 the corolla-segms. broad, almost square in outline and 

 toothed, creamy yellow with a dark crimson blotch on 

 the upper segms. A garden hybrid. G.C. III. 51:218.

F. TRACY HUBBARD. 



RfilDIA: PhyUanthus. 



REINECKIA (J. Reinecke, a German gardener). 

 Liliacese. A tender perennial herb, with attractive 

 foliage in tufts 1-1 H ft. high from a thick, creeping 

 rootstock: Ivs. rather long, channeled: scapes leafless: 

 fls. sessile, in a loose spike; perianth-tube cylindrical; 

 lobes recurved, spreading; ovary 3-loculed, with a few 

 seeds to each cell : berry globular, usually with 1 seed 

 to each cell. A single species from China and Japan. 

 The following is procurable from Dutch bulb-growers. 

 B. carnea, Kunth. Fls. dull flesh or pink: bracts rather 

 large, tinted red: fr. red, 3-4 lines diam. Var. variegata, 

 Hort., is also offered. I.H. 9:323. 



REIN ORCHIS: Habenaria. 



REINWARDTIA (named in honor of Kaspar Georg 

 Karl Reinwardt, 1773-1822, scientist of Leyden). 

 Linacese. Subshrubs, sometimes nearly shrubs, suitable 

 for the warmhouse. 



Leaves alternate, entire or crenate-serrate; stipules 

 minute, subulate, caducous: fls. yellow, in axillary and 

 terminal cymose fascicles, rarely solitary; sepals 5, 

 entire, lanceolate, acuminate; petals 5, contorted, 

 fugacious, much longer than the sepals; stamens 5; 

 ovary 3-5-celled: caps, globose, splitting into 6-8 cocci. 

 Two species, India. The genus is closely allied to 

 the flax (Linum), and Reinwardtia trigyna is known 

 to this day as Linum trigynum by the gardeners, who 

 usually accent trigynum on the second syllable instead 

 of the first. Reinwardtia is distinguished from Linum 

 by the yellow fls., 3-4 styles and unequal or deficient 

 glands; Linum has mostly blue, rosy or white fls., 5 

 styles, and equal glands. 



Reinwardtias are showy subshrubs about a foot high 

 with bright yellow flowers. They are useful for the dec- 

 oration of the conservatory in winter time, at a season 

 when yellow is scarce. To have presentable plants, it is 

 necessary to give them 

 a good deal of atten- 

 tion. It is difficult 

 sometimes to get suit- 

 able cuttings; the 

 strong growths which 

 start away from the 

 base when the plants 

 are cut down make 

 the best plants. Top- 

 shoots will grow, but 

 seldom make good 

 plants, as they are 

 liable to go to bloom 

 prematurely. Sandy 

 loam is the best com- 

 post. Plants that have 

 been grown in pots for 3360. Reinwardtia trigyna.
