fmaller whitilh flowers : the other much taller, even twenty 

 feet high, with large purple Jlo<wers, and much larger kavet, 

 whofe two fides are more alike in colour than the common 

 maximum. This lall variety, which we too have feen in Mr. 

 Vere's curious garden at Keniington Gore, merits further 

 examination, having certainly more refemblahce to pom 

 than to maximum, except its gigantic nature, which far 

 exceeds both.

 drum. Willd. n. 10. Ait. 11.9. Purfh 11.2. Andr. 

 Repof. t. 36. Venten. Jard. deCels, t. 15. — Leaves ellip- 

 tic-oblong, acute ; fmooth above ; fprinkled with minute 

 relinous dots beneath. Umbels iurmounted by tiie branches. 

 Segments of the calyx rounded, very (hort. Corolla funnel- 

 fhaped, If "'is externally. — Native of the mountains of 

 South Carolina, from whence it was brought to England 

 by the late Mr. John Frafcr, in 1791. It fucceeds well in 

 our gardens on a peat border, flowering early in the fummer. 

 This is a much humbler ihrub than any of the varieties of the 

 maximum, though its mode of intlorefcence accords with 

 that fpecies. The corolla is rofc-coloured, dilated and wavy 

 as in R. pontic urn, but fmaller ; its outiide rough or glandu- 

 lar, as in the ferrugineum. The leaves are elliptical, coria- 

 ceous, acute at both ends ; dark green and very fmooth 

 above ; paler, fomewhat nifty, and very thickly befprinkled 

 with glandular relinous dots, beneath.

 bell-lhaped. — Native of the high mountains of Virginia and 

 Carolina, particularly on the head waters of the Catawba 

 river, flowering in May and June. Purfh. Mr. Frafer 

 introduced it here in 1809, and brought a report of the 



jloiuers being fcarlet ; but they have fince proved of a pale 

 purphih rofe-colour, with very flight traces of thofe green 

 dots within, which make fo great a part of the beautyof 

 R. maximum. 'V\\>ejlirub is of a very humble fize, hardly 

 three feet high, and flowering before it attains even that 

 height ; but all its parts are large. The leaves are broad, 

 coriaceous, rounded and blunt at both ends ; paler beneath, 

 and very obfeurely dotted on the veins. The fegments of 

 the calyx arc laid to be remarkably elongated, an eflential 

 mark of dillinction, which ought to have been (hewn in 

 the, otherwife excellent, figure. We cannot help wilhing 

 alfo that the uncouth nam^, given by Michaux, had not 

 bi .1 retained ; but who lhall cleaufe the Augean liable of 

 modern botanical nomenclature? 



Rhododendrum, in Gardening, contains plants of the 

 hardy, deciduous, and evergreen, flowering, Ihrubbv 

 kinds, the dwarf rofe-bay, of which the fpecies cultivated 

 are, the rully-leaved rhododendrum 1 R. ferrugineum) ; the 

 hairy rhododendrum ( R. hirfutum) ; the dwarf rhododen- 

 drum, or role-bay ( R. cham ) ; the purple rhododen- 

 drum (R. ponticum) ; and the broad-leaved rhododendrum 

 (R. maximum).

fituation, on a loamy foil, covering the ground about the 

 roots with mofs, to guard them "from the froft in winter 

 and keep the ground moill in the fummer feafoti. They 

 may alio be increafed from fuckers or offsets, which they 

 pr iduce plentifully where they grow naturally, but I ■Mom

And they are very ornamental in the border, clumps, and

RhodoSENDBI m Cry/authemum, golden-flowered rhodo- 

 dendrum, in the Materia Medico. The leaves of this fpecies 

 are tiled in medicine. They are inodorous, and have an 

 auiterc, ailringent, bitterifh talte. Water extracts their 

 virtue either by infufion or decoction. Thefe leaves arc 

 toned (limulant, narcotic, and diaphoretic. Upon being 

 taken, they firil increafe the arterial action and heat of the. 

 body, producing diaphordis, which effects, according to Dr. 

 Home, are followed by a proportional diminution of excite- 

 ment : the pulfe in one cafe having been reduced 38 beats. 

 In large dofes, they produce naufea, vomiting, purging, 

 delirium, and all the fymptoms of violent intoxication. The 

 plant and its effefta were lirll defcribed by Gmclin and 

 Steller in 1747, as a Siberian remedy for rheumatifm ; but 

 it was not much noticed till after 1779, when Kcelpin flrongly 

 recommended it in this difeafe, and alfo in gout and lues 

 venerea. It has not been much ufed in this country ; but 

 from the refult of fome trials of it in Scotland, it obtained 

 a place in the Edinburgh Pharmacopeia. It has been given 

 in the form of decodlion, made by boiling Jiv of the leaves 

 in fjx of water, in a clofe vefl'el, over a flow lire, for 

 12 hours. The dofe of the flrained liquor is from fjj to 

 fj[ij given twice a day, and geaerallv 1. Woodv.
