The anthers are one-celled, and between 

 them and the ovaries are placed a number 

 of rudimentary flowers. The ovaries are 

 numerous, and partially three-celled, and 

 contain numerous ovules. R. vivipara is in 

 cultivation. [M. T. M.] 



REXAXTHERA. A genus of vandeous 

 orchids very nearly allied to Yanda itself, 

 from which it is technically distinguished 

 by its lip being articulated not continuous 

 with the column, and saccate or spurred at 

 its middle instead of at its base. The ori- 

 ginal species of the genus is a native of 

 Cochin China, but those since added, e»ight 

 or ten in number, are all confined to the 

 large islands of the Malayan Archipelago. 

 As ornamental plants they take rank with 

 the most beautiful of the orchid tribe, in 

 which they are also amongst the largest- 

 growing, their long branching and rooting 

 stems climbing on trees to a considerable 

 height. They have thick leathery strap- 

 shaped leaves regularly arranged in two 

 opposite rows ; and their flowers are dis- 

 posed in long panicles proceeding from the 

 sides of the stems. The most magnificent 

 and certainly the most remarkable species 

 of the genus yet known in this country, is 

 R Lowii, formerly Yanda Lowii, a native 

 of Borneo. This species grows to a great 

 height, and has leaves from half a yard to 

 a yard in length; and from near the top of 

 ! its stem it sends out several long slender 

 i pendulous flower-spikes, ten or twelve feet 

 ■. in length, clothed with numerous rather 

 ; large conspicuous flowers. These are of 

 ', two kinds, at least all the spikes that have 

 as yet come under notice have been fur- 

 : nished with a couple of tawny-yellow erim- 

 j son-spotted flowers at their base ; while all 

 the rest, forty or fifty in number, have been 



Of 



-greenish hue, marked inside with 



very large irregular blotches of reddish- 

 brown. [A. S.] 



REXEALMIA. A genus of Zingiberaceaz 

 named after the French botanist Renealme. 

 The species are tropical American herbs, 

 with creeping rootstocks, from which are 

 thrown up the two-ranked leaves, and pani- 

 cked inflorescence. The flowers are conceal- 

 ed within large bracts, and partake for the 

 most part of the botanical characteristics 

 of those of Alpinia. The lip of the corolla, 

 however, is erect, and embraces the very 

 short flattened filament ; and the three- 

 celled capsule splits into three pieces when 

 ripe. They have white flowers. [M. T. MJ 



RENGGERIA. A genus of Clusiacece 

 nearly related to Clusia, from which, ac- 

 cording to Mr. Bentham, it differs chiefly 

 in having from five to ten instead of a 

 much greater number of stamens to the 

 sterile flowers ; and from most others in 

 having many instead of few ovules to each 

 cell of the ovary, which when ripe is a 

 capsule. The four known species, found 

 ; in Brazil, Peru, and Guiana, are scrambling 

 | sennparasitical trees of low growth, with 

 opposite entire leathery leaves, the twigs 

 | terminating in panicles of yellowish flow- 

 ! ers, the sterile andf ertile on different trees. 



R. peruviana was at one time separated as a 

 genus under the name Rengifa. [A. A. B.j 



REXIFORM, The same as Kidney-shaped. 



REXXELLIA. A genus of Cinchonacem 

 whose species inhabit Sumatra. The in- 

 florescence is a terminal spike, the flowers 

 crowded and united one to another by the 

 confluence of the calyx-tubes. The free 

 margin of the calyx is unbroken ; the co- 

 rolla is tubular, its limb divided into four 

 spreading segments ; stamens four ; style 

 thread-like, surrounded at the base by a 

 fleshy disk, and dividing above into two 

 stigmas. Fruit of irregular shape, consist- 

 ing of several ovaries combined, and sur- 

 mounted by the persistent calyces and 

 disks. [M, T. M.J

REPEXT. Creeping; lying flat upon

 time. 



REPLICATE, REPLICATIVE. When 

 the upper part of a leaf is curved back 

 and applied to the lower, as in the Aconite. 



REPLUM. The valve of a door— ap-

 frame ; the frame left in certain fruits by 

 the dropping-off of the valves in the act 

 of dehiscence.

REPTOXIA. This genus is interesting 

 because of its botanical affinities. It is 

 usually placed in the Myrsinacece, with 

 which it accords in the one-celled ovary ; 

 but on the other hand it is close to the 

 Sapotacew, having five sterile filaments al- 

 ternating with the five fertile ones which 

 are opposite the corolla-lobes ; the leaves 

 have no transparent dots as have most 

 Myrsinacea ; and the seeds, with rumi- 

 nated albumen, are unlike any in either 

 of the two families. R. buxifolia, the 

 only known species, is found in Affglian- 

 istan and on the shores of the Persian Gulf 

 opposite to Muscat; it is a rigid ever- 

 green hardwooded bush, with alternate en- 

 tire leaves, and short lateral shoots termi- 

 nating in spiny points like those of the sloe. 

 The small yellowish flowers, arranged in 

 clusters in the axils of the leaves, have 

 each a five-cleft calyx with rounded lobes, 

 a shortly tubular corolla, and an ovary re- 

 markable for its slender style being pro- 

 truded while the flower is yet in the bud. 

 According to Griffith, the rounded black 

 edible drupes, of the size of marbles, are
