RHIZOTHQRA. Mangrove. (From rhiza, a root, 

 and phoreo, to bear ; the branches send down roots like 

 the Banyan-tree. Nat. ord. Mangroves [Rhizophoraceae], 

 Linn. n-Dodeoandria, i-Monogynia.) 



Not likely to be much cultivated until we obtain 

 salt-water aquariums in our large tropical houses. The 

 Mangrove flourishes in rich, loamy soil, in thickets, by the 

 side of the ocean, in tiopical latitudes, and possesses 

 the striking feature that the seeds vegetate while attached 

 to the plant, and send out a long radicle, which generally 

 reaches the soft mud, while the top puts out leaves ; 

 numbers of plants are thus joined together, something 

 in the same way as the Banyan-tree. 

 R. Ma'ngle (Mangle). 10. Pale yellow. E. Ind. 1820. 



RHODA'MNIA. (From rhodamnos, a flexible branch ; 

 in allusion to the slender, twiggy character of the plants. 

 Nat. ord. Myrtaceae. Allied to Myrtus.) 



Greenhouse, evergreen shrubs or small trees. Cuttings 

 in sand, under a hand-light. Fibrous loam, peat, and 

 sand. The one-celled ovary is remarkable in the order. 

 R. arge'ntea (silvery). 5-10. White. Australia. 

 ,, trine'rvia (three-nerved). 15. White. May. India ; 

 Malaya ; Australia. 1824. 



RHODA'NTHE. (From rhodon, a rose, and anthos, a 

 flower. Nat. ord. Composites [Composite?]. Linn. 19- 

 Syngenesia, i-jEqualis. Referred to Helipterum.) 

 R. atrosangui'nea (dark-blood-red). See HELIPTERUM

RHODDON, or RODDON-TREE. Py'rus Aucupa'ria.

 RHO'DIOLA RO'SEA. See SEDUM ROSEUM. 



RHODOCHI'TON. (From rhodon, red, and chiton, a 

 tunic or cloak ; referring to the large, cloak-like red 

 calyx. Nat. ord. Scrophulariacese. Allied to Maur- 

 andia.) 



A greenhouse, evergreen climber. Seeds ; cuttings in 

 sand, under a bell-glass, during late summer. Fibrous 

 loam, leaf-mould, and sand. 



R. volu'bile (twining). 10-12. Blood-red ; calyx purple- 

 red. June to August. Mexico. 1833. 



RHODODEN'DRON. Rose Bay. (From rhodon, a 

 rose, and dendron, a tree ; in allusion to the colour of 

 R. ponticum. Nat. ord. Heathworts [Ericaceje]. Linn. 

 iQ-Decandria, i-Monogynia.) 



Seeds in spring, in shallow pans, in sandy peat, and kept 

 in a close, cool frame until the seedlings are fit to be 

 handled, when they should be pricked off into similar 

 soil, and gradually exposed to sun and air ; layers, either 

 in spring or autumn ; cuttings of young shoots, when the 

 base close to the older wood is getting firm, inserted in 

 silver sand, and placed, at first, in a cold frame, and 

 afterwards in a little bottom-heat ; sandy peat is the 

 best ; sandy, fibrous loam and clayey loam the next ; 

 kitchen-garden soil, and soil of any kind containing or 

 resting upon calcareous matter, the worst. The varieties 

 of the arbo'reum, campanula' turn, &c., require a little pro- 

 tection to have them in their beauty. See AZALEA for 

 old varieties.
