 are by no means proper, becaufe the 

 Steam of the Dung will cafily get 

 through every little Crack or Joint

 of the Trees : befides, thefe Boards 

 will continue very damp, fo long as 

 any Moillure remains in the Dung, 

 which will alfo be very injurious to 

 them ; and as thefe Beards will in a

WALTHERIA. 

 The Characters are ; 



It is a Plant of the malvaceous 

 Tribe : the Empi lament of tht Flower 

 is of one Leaf fight ly cut at theBrim 

 into fovc Farts : the Flower is com- 

 pos! d of five Leaves, which fpread 

 open : in the Centre is fituated the 

 oval Point al, attended by five Stami- 

 na, which coalefce vjith the Style, fo 

 as to form one cylindrical Body : the 

 impalement inclofcs cue Seed-veffel, 

 which opens in t/WQ Valves, having 

 one obtufe Seed.

This Genus of Plants is defcrib'd 

 in the French Memoirs of the Aca- 

 demy of Sciences by Monf. D * Ifnard, 

 who has given it the Title of Mono- 

 fpermalthfsa: from the Habit of the 

 Plant being'like Alt ha: a, but having 



a fingle Seed to each Flower, he 

 compounded this Name : but Dr. 

 Linnaus has altered it to this of Wal- 

 thtria, in Honour to Auguflus Fre- 

 Jeric Walt her, Profeflbr at Leipjic, 

 who is a curious Botaniit. 



Both thefe Plants grow plentifully 

 in moft of the I Hands in the Wefl- 

 Indies, from whence I have receiv'd 

 their Seeds, which have fucceeded 

 very well ; and the Plants perfect 

 their Seeds annually, when they are 

 plac'd in the Tan- bed in the warm 

 Stove. . 



They grow fhrubby, and rife to 

 to the Height of fix or eight Feet, 

 fending out long lateral Branches, 

 which are garniuVd with foft woolly 

 Leaves, placed alternately. The 

 Flowers are fmall, of a yellow Co- 

 lour, and are many of them collect- 

 ed in an Head. Thefe grow upon 

 long Foot-ftalks, which arife from 

 the Wings of the Leaves/ The 

 Flowers are of fhort Duration, and 

 make butt an indifferent Appearance ; 

 fo the Plants are feldom preferved, 

 but in Botanic Gardens, for the fake 

 of Variety. 



Thefe Plants are too tender to 

 live in the open Air in England, not 

 even in the Summer-feafon ; nor do 

 they thrive well, unlefs the Pots are 

 plungM in the Hot-bed of Tanners 

 Bark : fo that the Seeds mull be 

 fown on an Hot-bed, and when the 

 Plants are fit to tranfplant, they muft 

 be each planted into a feparate fmall 

 Pot, and plung'd into a frefn Hot- 

 bed ; and afterward treated in the 

 fame manner, as other tender Plants 

 of the fame Country. The fecond 

 Year the Plants will flower, and pro- 

 duce good Seeds; but they may be 

 continued three cr four Years, if the 

 Plants are often fnifted, and their 

 Roots pared,- to keep them within 

 Compafs ; for if the'Plants are per- 

 mitted, to remain long undifturbed
