REEVfiSIA (John Reeves, English botanist, who re- 

 sided for a time at Canton). Sterculidceoe. A genus of 

 3 species of trees from tropical Asia, with coriaceous, 

 entire leaves and terminal corymbose panicles of white 

 fls. Calyx club-shaped or campanulate, irregularly 3-5- 

 lobed; petals 5, oblong, furnished with a claw; stami- 

 nal column long, adnate to the gynophore; anthers 15, 

 sessile, in a globular head : ovary 5-loculed, usually 10- 

 seeded: capsule woody: seeds winged.

 green, 2-6 in. long, petioled, ovate-lanceolate to lanceo- 

 late, entire, rounded at base: fls. white, in terminal, 

 sessile corymbs shorter than the lvs. ; calyx 3 lines 

 long ; petals somewhat longer : capsule oblong-pear- 

 shaped, 1 in. long, 5-angled. China. B.M. 4199. B.R.

REIN£CEIA (J. Reineeke, a German gardener). 

 Ziiliare(e. A genus of a single species from China and 

 Japan, a tender perennial hei'b, with attractive foliage 

 in tufts 1-1>2 ft. high from a thick, creeping rootstock. 

 Lvs. rather long, channeled: scapes leafless: fls. sessile, 

 in a loose spike; perianth-tube cylindrical; lobes re- 

 curved, spreading: ovary 3-loculed, with a few seeds to 

 each cell : berry globular, usually with one seed to each 

 cell. The following is procurable from Dutch bulb- 

 growers. 



Cornea, Kunth. Fls. dull flesh or pink: bracts rather 

 largf-, tinted red: fr. red, 3-4 lines in diam. B.M. 739. 

 -Var. varieg^ta is also offered. I.H. 9:.323. 



borne in midwinter. They are old favorites in conser- 

 vatories. They require warmhouse treatment. The genus 

 is closely allied to the flax (Linum), and Meinwardtia 

 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. Other generic characters: 

 sepals 5; petals 5, contorted, fugacious; stamens 5, 

 alternating with as many staminodes; glands 2-3, ad- 

 nate to the staminal ring: ovary 3-5-loculed. 



Reinwardtias are showy subshrubs about a foot high 

 with bright j'ellow 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 attention. It is 

 diflicult sometimes to get suitable 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 

 compost. Plants that have been grown in pots for a 

 season may be planted out in the early summer, and 

 these will make good plants and furnish cuttings. They 

 will have to be topped frequently and carefully lifted. 

 Young stock is better kept in pots, as the plants do not 

 lift well. Sunshine is essential during the winter season 

 to get the best development of Reinwardtias. They 

 thrive best in a temperature of 55-60°.

RENANTHERA (named from the reniform anther), 

 Orchiddcece. Tall, climbing epiphytes, with branched' 

 stems sometimes 12-14 ft. high: lvs. distichous on the 

 stem: fls. in large, drooping racemes or panicles; sepals 

 and petals spreading, similar or the lateral sepals often 

 larger and of a different color; labellura small, movably 

 joined to the column, spurred or spurless, often with 

 small, erect, lateral lobes. Culture is similar to that of 

 yE rides and Vanda.

 across, in loose, branching racemes 2-3 ft. long, very 

 brilliant; petals and dorsal sepal linear-spatulate, deep 

 red, blotched with orange; lateral sepals larger, oblong, 

 broader toward the apex, xindulate, deep crimson, with 

 paler transverse lines; labellum small. Autumn.
