RAVEXALA 



REHMANNIA 



2915 



Calif.; also rarely under glass in the northern states. 

 It is said that in S. Calif, the traveler's tree was never 

 really successful. 



AA. Lvs. as long as the petioles. 



guyanensis, Steud. Becoming 15 ft. high: Ivs. oval- 

 elongated: fls. white; spathes 1-1 *4 ft. long. Offered 

 1893 in S. Fla. F. W. BARCLAY. 



RAVENIA (name not explained). Rutacese. Tender 

 glabrous shrubs suitable for the wannhouse. 



Leaves opposite, 1-3-foliolate ; Ifts. lanceolate, entire: 

 fls. red or white, borne on rather long axillary pedun- 

 cles; sepals unequal, the 2 outer being somewhat folia- 

 ceous; corolla-tube straight, rather long; the limb nearly 

 regular. Two species from Cuba and Brazil. 



spectabilis, Griseb. (Lemon i a spectabilis, 

 Lindl.). Tender shrub: Ifts. 3: fls. purplish red, 

 about 1 in. across, solitary or in open, few-fid, 

 clusters on axillary peduncles as long as the Ivs. 

 Cuba. B.R. 26:59. R.H. 1844:25. The plant 

 once offered in Fla. as Lemonia spectabilis appar- 

 ently is of some other genus. j\ \y. BARCLAY. 



REBUTIA (named for Rebut). Cactacese. 

 Plants very small, globular, covered with small 

 tubercles, resembling in habit very much a mam- 

 millaria: fl. appearing from the side and even 

 the base of plant, large in comparison with the 

 plant, red or orange-colored, with slender, fun- 

 nelform tube; bracts on ovary small, naked in 

 their axils: fr. a small berry. Originally de- 

 scribed with 1 species, but a study of S. Ameri- 

 can material indicates that there may be 5 or 6 

 other species to be transferred here from other 

 genera. The original species has been referred 

 lx>th to Echinopsis and Echinocactus, from both 

 of which it is abundantly distinct. 



minuscula, Schum. Plants globose, 1-2 in. 

 diam.. covered with low tubercles: spines in 

 clusters of 25-30, 1-1 H lines long: fls. often 

 numerous, arising from near the base of plant, 

 1-1*4 in. long, bright crimson. X. Argentina. 

 B.M. 8583 (as Echinocactus). 



Fiebrigii, Brit. & Rose (Echinocactus Fiebrigii, 

 Gurke). Globose, depressed at apex, 2 in. diam.: 

 spines 30-40 in a cluster, Yi\&.. long, white, or 

 some of the longest ones nearly 1 in. long with 

 brownish tips: fls. nearly 1 in. long. Bolivia. 

 Bluhende Kakteen, pi. 109. j. x. ROSE.

 Lychnis dioica. Red Cedar: Juniperus rirginiana. Redhead: 

 Asclepias curassarica. Red-hot Poker Plant: Kniphofia. Red

 dinacea. R., Indian : Canna. R. Mace, or Cat-tail: Typha. 



REEVESIA (after John Reeves, an English resident 

 of Canton. China, who introduced many Chinese plants 

 into England). Stercidiacex. A genus of 3 species in 

 China and Himalayas. Evergreen trees with alternate, 

 simple, entire Ivs. 3-nerved at the base and with white 

 or pink fls. in dense terminal corymbs: calyx funnel- 

 form-campanulate, 4-5-toothed; petals 5, clawed; 

 stamens adnate to the long gynophore, much exceeding 

 the petals, 15, forming a globose head; ovary 5-lobed; 

 stigma sessile: caps, large, woody, septicidally 5-valved, 

 seeds 2 in each cell, compressed, winged. Little known 

 in cult, and adapted only for warmer temperate regions. 

 Prop, probably by cuttings from half-ripened wood. 

 R. thyrsoidea, Lindl. Evergreen shrub: Ivs. ovate - 

 oblong to oblong-lanceolate, glabrous, 2-5 in. long: fls. 



creamy white, J^in. across; gynophore YT^A m - long. 

 China. B.R. 1236. B.M. 4199. F.S. 3:206. R. pubes- 

 cens, Mast. Similar to the preceding: Ivs. ovate to 

 ovate-oblong, subcordate to broadly cuneate at the 

 base, brownish tomentose beneath, 35 in. long: fls. 

 somewhat larger, pink; gynophore 1 in. long. E. 

 Himalaya, S. W. China. Recently intro. 



ALFRED REHDER. 



REHMANNIA (Jps. Rehmann, 1779-1831). Scro- 

 phularidcese. Perennial viscous-villous herbs suitable 

 for the cool greenhouse, grown for the showy bloom. 



Stems leafy, branched from the base, either low. 

 scapiform and almost leafless, or (especially in cult.) tall 

 and few-lvd. : Ivs. alternate, obovate or oblong, coarsely 



3358. Traveler's tree. Ravenala madagascariensis. 



dentate: fls. rather large, borne in terminal racemes 

 and short-pedicelled. brownish purple or pale, the 

 throat intensely colored; calyx ovoid-campanulate, 

 5-cleft at the top; corolla pilose, slightly incurved, tube 

 rather broadly subventricose, limb obliquely 2-lobed, 

 the lobes spread, the rear or inner one deeply 2-cleft, 

 the front one 3-cleft; stamens 4: caps, broad, partly 

 included in the calyx; seeds numerous. About 5 

 species, China and Japan. 



angulata, Hemsl. Perennial plant, 1-3 ft. high, 

 glandular-hairy: Ivs. pinnately lobed, each side of If. 

 having either very many marginal teeth, or, if there are 

 a few lobes or large teeth, by these being again toothed; 

 the bracts broadly and abruptly cuneate at the base 

 which is wider than any other part of the blade: corolla 

 smaller than R. elata, red with a band of scarlet at the 

 margin of the upper lip and has orange dots inside the 

 lower lip. China. G.C. III. 33:296; 47:104. G. 25: 171; 

 28:211. Gn. 63, p. 317. G.M. 46:290; 51:745. Gn. 

 W. 21:117. Gt. 55:1547. G.W. 9, p. 114; 11, p. 488; 

 12, p. 362. J.H. III. 46:422; 71:11. R.H. 1905:586. 

 F.S.R. 2:280. F.E. 20:526. Many of these illustra- 

 tions are probably of R. elaia. 



Var. tigrina, Hort., is said to be a garden hybrid of 

 which R. angulata is one of the parents: fls. marked. 

 An interesting form.
