it by the five sepals being equal and 

 widely spread, and by the stamens being 

 only ten in number. It has twisted branch- 

 es, oval or oblong leaves, and short-stalked 

 yellow flowers produced along the upper 

 part of the young angular branches, and 

 forming a kind of raceme. [A. S.] 



RECEPTACLE. A general term expres- 

 sive of a part which receives or bears other 

 parts: as the receptacle of flowers or cli- 

 nanthium, the receptacle of fruits or torus, 

 the receptacle of ovules or placenta. Re- 

 ceptacles of oil are cysts formed among 

 the cellular tissue of plants and containing 

 an oily secretion, as in the so-called dotted 

 leaves of the orange. Receptacles of se- 

 cretion are those cavities of the interior of 

 a plant into which natural secretions are 

 drained. 



RECESS. The same as Sinus. 



RECHSTEINERA. A genus of Ges'ne- 

 racem inhabiting Brazil, of which R. alla- 

 gophylla (Gesnera allagophylla of the gar- 

 dens) is the type. They have large tubers, 

 an erect hairy stem, opposite or ternate 

 linear or oblong leaves, and a terminal 

 spike of fine scarlet or yellow flowers. The 

 nearly bilabiate corolla is scarcely double 

 the length of the five-cleft calyx ; and the 

 ovary is surrounded by five glands, two of 

 which are larger than the rest. R. alla- 

 gophylla has long been a favourite in our 

 hothouses, on account of its gay orange- 

 scarlet flowers. [B. S.] 



RECLINATE, RECLINING. Bent down 

 upon some other part ; falling gradually 

 back from the perpendicular, as the branch- 

 es of many trees. 



RECONDITE. Concealed ; not easily to 

 be seen. 



RECTEMBRYJE. A suborder of Sola- 

 nacece, consisting of those plants in which 

 the embryo is straight, as distinguished 

 from Curvembryce, in which it is curved. 



RECTINERVIS, RECTINERV1US. The 

 same as Parallelinervis. 



RECTIVENIUS. Straight-veined; hav- 

 ing all the veins parallel, as in the leaves of 

 a grass. 



RECTUS. In a right line ; not wavy or 

 curved, or deviating from a straight direc- 

 tion in any way.

 VUS. Bent, but not rolled backwards.

 Ceanothus americanus ; also an American 

 name for Lachnanthes. 



RED-ROT. Drosera. 



RED-SHANKS. Polygonum Persicaria; 

 also Geranium Robertianum. 



RED SNOW. The common name of Pro- 

 tococcus nivalis, which in an incredibly 

 short space of time produces large patches 

 of a brilliant scarlet on the surface of snow 

 in the Arctic regions or amongst the Alps. 

 A species of Protococcus, which is almost 

 identical with P. pluvialis, is common upon 

 leaves, straws, little pebbles, &c. where 

 water has rested ; and has given occasion 

 to Shuttleworth, Cohn, and others for a 

 tolerably perfect study of this strange pro- 

 duction, which before the discovery of the 

 propagation of so many Alga? by zoospores 

 must undoubtedly have been referred to 

 the animal kingdom. The endochrome is j 

 divided into a definite number of cells, j 

 each of which becomes anew individual. | 

 Some become naked active cells moving by 

 two flagelliform processes, or these cells I 

 are surrounded by a hyaline sac, and with- ' 

 in the sac are definitely divided into a 

 number of new individuals. Occasionally , 

 the division goes so far that their number j 

 is apparently indefinite. It is impossible ; 

 within our limits to trace each further j 

 change, for which we must refer to Cohn's 

 paper (Nachtrage zur Naturgeschichte des j 

 Protococcus pluvialis). The spores, as in ! 

 many other minute Algaz, are in some stages I 

 green, in some scarlet. [M. J. B.] j

REDWOOD. An East Indian dye-wood, 

 the produce of Pterocarpus santalinus ; also 

 Erythroxylon. The Redwood of the Turks 

 is Gornus mascula; that of the timber 

 trade is furnished by Sequoia sempervirens.
