HENDERSON'S HANDBOOK OF PLANTS 



EEH 



Rehma'nuia. Named in honor of Joseph Reh- 

 mann, a phj'sician of St. Petersburgh, 1779- 

 1831. Nat. Ord. Serophulariacem. 



A genus of two species of liardy perennial 

 plants, natives of China and Japan. R. Chin- 

 ensis is a very handsome, dwarf-growing plant, 

 producing in summer large tubular flowers of 

 a purplish color striped with a darker hue. It 

 succeeds best planted in a moist, shady border, 

 and requires to be wintered under glass. It 

 is increased by cuttings. Syn. R. glutinosa. 



Rei'dia. An honorary name. Nat. Ord. Euphor- 

 biacecB. 



A genus of about a dozen species of green- 

 house shrubs, allied to Phyllanthus, and by 

 some authors included under that genus. 

 They are small bushes, having slender twigs 

 furnished with numerous small, entire leaves, 

 bearing in their axils, either singly or in 

 clusters, small greenish or whitish flowers 

 tipped with pink. Some of the species arc 

 very pretty, though not considered useful 

 flowering plants. They are mostly natives of 

 the East Indies. They were first introduced 

 in 1864, and are propagated by root cuttings. 



Reindeer Moss. See Lichen. 



Reine'ckea. Named in honor of J. Reineckfi, a 

 successful cultivator of tropical plants. Nat. 

 Ord. LiliacecB. 



R. carnea, formerly called Sansevirra cnmea, 

 the only known species, is a very pretty, hardy, 

 herbaceous perennial inhabiting the marshy 

 districts of Japan. It has grassy leaves six 

 inches to a foot long, from the midst of which 

 arises a flower stalk three or four feet high, 

 bearing a number of rose-colored, or purple, 

 fragrant flowers, each seated in the axil of a 

 bract. The plants are well adapted for the 

 aquarium or margins of fountains. A beauti- 

 ful variegated variety is in cultivation, but 

 requires to be pot-bound, or grown in poor 

 sandy soil, or lime-rubbish, to retain its varie- 

 gation. Propagated by offsets. 



Rein Orchis. See Habenaria. 



Rein-wa'rdtia. Named after K. G. K. Rein- 

 icardt, once director of the Botanic Garden at 

 Leyden. Nat. Ord. LinacecE. 



A genus found in the mountain regions of 

 India, consisting of three species which were 

 formerly included under Limim, but from 

 which they differ botanically. R. triginum 

 (syn. Linum) is an erect branching, deciduous- 

 leaved bush cultivated for its handsome yellow 

 flowers, which are nearly one and a half inches 

 across and are all the more highly prized that 

 they are produced freely in winter. Easily 

 propagated by cuttings or pieces of the creep- 

 ing root. R. tetraginum is a later introduction 

 from the mountains of India. It has alternate, 

 deep green leaves, its beautiful yellow and 

 orange flowers being borne five or six at a 

 time on each branch, in terminal or axillary 

 racemes. It is an excellent free-flowering 

 winter green-house plant. 



Rena'nthera. From ren, a kidney, and anthera, 

 an anther or pollen-bag ; in allusion to the 

 kidney or reniform shape of the anthers or 

 pollen masses. Nat. Ord. Orchidacem. 



A small genus of epiphytal Orchids, mostly 

 rare, and exceedingly beautiful. R. Loieii is a 

 remarkable species, a native of Borneo. This 

 species grows to a great height, and has leaves 

 from two to three feet long, with pendulous 



RET 



flower stems ten or twelve feet in length, 

 clothed with numerous large, conspicuous 

 flowers, resembling some large insect. It is 

 allied to Vanda, and requires to be grown in a 

 high, moist temperature. Introduced in 1843. 



Reniform. Kidnej'-shaped in outline. 



Repens. Creeping. 



Replicate. Folded backwards. 



Rescue Grass. Bromus Schrcrderi. A valuable 

 forage grass, thriving in any soil, but prefer- 

 ring that which is wet or moist. 



Rese'da. Mignonette. From rcsedo, to calm 

 or appease. The Latins considered its appli- 

 cation useful in external bruises. Nat. Ord. 

 ResedacecB. For description of this genus see 

 Mignonette. 



Reseda'ceae. A natural order of annual or per- 

 ennial herV)s, with alternate, entire, or pin- 

 nately-dividf'd leaves, and minute gland-like 

 stipules. They are natives chiefly of Europe, 

 northern Africa and Western Asia, but a very 

 few occur in southern Africa and northwest 

 America. R. luteola, the wild yellow-weed, 

 or Dj'er's-weed, was formerly in great demand, 

 affording, as it does, a beautiful yellow dye. 

 The order contains about six genera and 

 thirty species. 



Resin Plant. A common name for Bursera 

 acuminntn, and B. gummifera, Dammara Avs- 

 trali.'^, Guiacum officinale, etc. 



Restharrow. See Ononis. 



Restia'ceae. A natural order of perennial herbs, 

 with horizontal or creeping rhizomes, mostly 

 natives of Australia and .southern Africa. TIh^ 

 order comprises twenty genera and about 230 

 species, few of which are of any horticultural 

 value. Restio and Willdenowia are the best 

 known examples. 



Re'stio. From resti^, cord ; alluding to the use 

 of the plants in South Africa. The grass-like 

 plants of this genus are used as cord at the 

 Cape of Good Hope. The species are only of 

 botanical interest. 



Restre'pia. Named in honor of Joseph E. 

 Restrep, a naturalist who traveled in South 

 America. Nat. Ord. Orchidacem. 



A small genus of epiphytal Orchids from 

 Central America. They are very pretty little 

 plants, with curious, many-colored flowers. 

 They are of easy culture in a cool house. They 

 all flower freely in summer, and should be 

 grown in pots in leaf mould and sphagnum 

 moss. They were first introduced in 1843, 

 and are propagated by division. 



Resupinate. Inverted in position, appearing 

 as if upside down. 



Resurrection Plant. A popular name given to 

 Anastatica Hierochuntina and Selaginella lepi- 

 dophylla. 



Reticulate. Resembling net-work. 



Retiiio'spora. Japan Cypress. From retine, 

 resin, and spora, spore or seed. Nat. Ord. 

 Conifcrm. 



A genus of very beautiful, hardy evergreens, 

 mostly dwarf and compact, particularly 

 adapted for lawn decoration. They aii' 

 closely allied to Cupressus, and are propagated 

 in the same manner. The Japanese Retino- 

 sporas are among the most beautiful of small 

 evergreen trees. They are fine subjects for the 

 lawn, are hardy in the latitude of New York,
