Renanthera continued. 



freely every summer, if placed in a sunny position and 

 kept moist. R. Lowii should be grown in the hottest and 

 moistest house, in a sunny position ; but its roots prefer 

 a large pot filled with drainage, sphagnum, and lumps of 

 fibry peat. R. Storiei is a rare plant, seldom seen in 

 cultivation, and then always in bad health. It is usually 

 potted in sphagnum and crocks, and placed in a tropical 

 house along with Phalcenopsis. The other species, not 

 already mentioned, require similar treatment. 

 R. cocclnea (scarlet).* JL of a beautiful blood-red within, dis- 

 posed in very large panicles; lateral sepals oblong-spathulate, 

 obtuse ; dorsal one and petals linear-ligulate ; middle lobe 

 of lip bigibbous at base; spur acute, conical, straight. I. 

 ligulate, obliquely emarginate at apex. Aerial roots very long. 

 Cochin China, 1816. A splendid plant. (B. M. 2997 ; B. R. 



R. elongate (elongated). Jl. purplish ; lateral sepals unguicu- 

 late ; lateral lobes of lip sometimes sinuate, the middle lobe 

 triangular and very short, bicallous at base ; spur obtuse, conical ; 

 panicle elongated, nodding. I. broadly linear, oblique, emar- 

 ginate. Kuripan. (B. R. 1843, 41.) 



R. histrionica (acting). Jl., sepals and petals yellow, bordered 

 with purplish blotches ; lip white, with purplish blotches on the 

 side lobes ; spur orange ; racemes short, few-flowered. I. acumi- 

 nate. Malacca (?), 1878. 



R. Lowei (Lowe's).* /., two kinds on the same spike, the lowest 

 pair always tawny-yellow enlivened with crimson dots, the 

 remainder pale green, almost hidden on the inner side by large, 

 irregular blotches of reddish-brown ; sepals and petals waved, 

 lanceolate, acute, those of the lowest pair more blunt; spikes 

 pendent, 6ft. to l2ft. long, bearing from thirty to fifty flowers. 

 Stems caulescent, lin. thick, climbing to a great height. Borneo. 

 (B. M. 5475.) The correct name of this plant is now Arach- 

 nanthe Lowei. 



R. matutina (morning). Jl. at first of a very beautifid blood- 

 colour, paler outside, the disk of the lateral sepals golden, the 

 bases of the petals striped with dark purple ; lip very minute, 

 dark purple ; panicles much-branched, 2ft. to 3ft. long ; peduncles 

 intense purple. I. ligulate, obtuse and unequally bilobed at apex ; 

 sheaths sometimes violet. 



R. m. breviflora (short-flowered). A distinct variety, differing 

 from the type in its shorter sepals, the lateral ones more free from 

 one another, and the calli under the column larger. Sunda Isles, 

 1879. 



R. moluccanum (Moluccan). Jl. red, dotted ; sepals all linear- 

 ligulate ; lateral lobes of lip bilobulate ; middle lobule not 

 callous at base; peduncles long-exserted at the apex of the 

 pai.icle. I. shortened, oblong, obtusely bilobed at apex. Am- 

 boyna, 1846. 



R. Storiei (Stone's), fl. more than 2in. across ; dorsal sepals and 

 petals dark orange ; lower sepals broad, of a brilliant velvety- 

 crimson, with lighter shades of the same colour ; lip small, deep 

 crimson, with small yellow bars, centre white. Philippines, 

 1880. 



RENEALMIA (named in honour of Paul Eenealme, 

 a French botanist, who published, in 1611, a " History 

 of Plants "). SYNS. Ethanium, Oethyra, Peperidium. 

 ORD. Scitaminece. A genus comprising about fourteen 

 species of stove, herbaceous perennials, natives of tropical 

 America, one being also found in tropical Western Africa. 

 Flowers one to three or many, beneath membranous, but 

 not imbricating, bracts ; calyx cup-like or loosely tubular, 

 shortly trilobed ; corolla tube short or rarely longer than 

 the calyx, the lobes erect, or at length spreading, sub- 

 equal, or with the dorsal one broader ; raceme or thyrse 

 sometimes on a leafless, scaly scape from the rhizome, 

 sometimes at the tip of a terminal, leafy stem. Leaves 

 two-ranked. The only species known to cultivation re- 

 quires culture similar to Alpinia (which see). 

 R. exaltata (exalted). A. scarlet, on one- to three-flowered pedi- 

 cels ; scape coloured, villous ; raceme elongated ; bracts lanceo- 

 late, as long as the flowers. July. fr. blackish-violet, oval, lin. 

 long, with aromatic seeds. I. sessile, lanceolate, glabrous, h. 2ft. 

 (sometimes, in a wild state, 8ft to 10ft. or more). West Indies, 

 1820. (B. M. 2494 and B. R. 7771, under name of Alpinia 

 tubulata.)

RESEDA (the old Latin name used by Pliny, from 

 reseda, to calm or appease ; the application of the plants 

 to external bruises was considered useful by the Latins). 

 Mignonette. OED. Resedacece. A genus of annual or 

 biennial, hardy, erect or decumbent, glabrous or pilose 

 herbs. About twenty-six may lay claim to specific rank ; 

 these are mostly natives of South Europe and North 

 Africa, and are also found in Syria, Persia, and Arabia. 

 Flowers racemose, bracteate ; calyx four to seven- parted ; 

 petals hypogynous, four to seven, unequal, two to many- 

 fid; torus sub-sessile. Capsule indehiscent, three-lobed 

 at apex. Leaves entire, lobed or pinnatisect; stipules 

 gland-formed. R. lutea and R. Luteola (Dyers' Eocket, 

 Dyers' Weed, or Dyers' Yellow Weed) are natives of 

 Britain. The latter plant was formerly in great demand 

 for dyeing purposes. Few of the species are of any great 

 value to horticulturists. R. odorata, the common Mignon- 

 ette, is one of our most highly -valued and sweet-scented 

 garden plants. For culture, enumeration of varieties, Ac., 

 see Mignonette. 



R. alba (white). Jl. with white petals and brownish anthers, 

 disposed in dense spikes ; calyx five or six-parted. May to Sep- 

 tember. I. all pinnatifid or sometimes interruptedly pinnate; 

 segments lanceolate, smooth, rarely waved. A. 2ft. South 

 Europe, 1596. Hardy biennial. (S. F. G. 459.) 

 R. frutescens (shrubby). A form of R. odorata. 



FIG. 360. CAPSULE OP RESEDA ODORATA. 



R. odorata (fragrant).' Common Mignonette. JL. with yellowish- 

 white petals and saffron anthers, disposed in loose racemes ; calyx 

 six-parted, equalling the petals, which are finely cleft into many 

 club-shaped divisions. June to October. L lanceolate, bluntish, 

 entire or trifld. North Africa, Egypt, <fcc., 1752. Plant diffuse. 

 See Fig. 360. (B. M. 29.) The variety frutescens is merely a 

 shrubby form of this species. (B. R. 227.) 



RESEDACEJE. A small natural order of annual or 

 perennial herbs, rarely shrubs, mostly found in South 

 Europe, North Africa, Syria, Asia Minor, and Persia; 

 a few reach the Indian frontier, and three inhabit the 

 Cape Colony. Flowers hermaphrodite or rarely unisexual, 

 racemose or spicate, one-bracted ; calyx persistent, four 

 to seven-parted, unequal or almost equal, the segments 

 imbricated; petals four to seven, rarely two (or none), 

 deciduous or persistent, hypogynons or perigynous, entire 

 or three or many- fid, ample, or with a membranous
