PU'ESHIA. (Named after F. Pursh, 

 writer on American plants. Nat. ord., 

 JRoseu-orts [Eosaceffi]. Linn., 12-Icos- 

 andria 1-Monoyynia. Allied to Agri- 

 monia.) 



Hardy evergreen shrub. Cuttings of young 

 shoots, in sand, under a hand-light, in early 

 summer ; also by seeds, treated as rose seeds ; 

 sandy poor soil.

A light rich soil they thrive in most, 

 and they must have a warm situation, 

 as a south border. Sow in February 

 and early in March, in a moderate 

 hotbed, to remain where sown ; and at 

 the close of March, and once monthly, 

 during April, May, and the summer 

 months until the end of August, in the 

 open ground. 



Sow in drills six inches apart, very 

 thin, and not more than a quarter -of- 

 an-inch deep. Keep the seedlings j 

 clear of weeds, and thin to six or eight i 

 inches asunder, In dry weather, water ; 

 moderately two or three times a-week. 



In general, they are ready for ga 

 thering from in six weeks after sowing, ; 

 the young shoots being made use of ; 

 from two to five inches in length, and 

 the plants branch out again. 



The hotbed crops require the air to 

 be admitted as freely as the weather 

 permits, the temperature ranging be- 

 tween 50 and 75. 



To obtain Seed. A few of the earliest 

 border-raised plants must be left un- 

 gathered from ; the strongest and 

 largest leaved being selected. They 

 must be cut immediately the seed is 

 ripe, laid on a cloth, and when perfectly 

 dry, thrashed, and the refuse is best 

 separated by means of a very fine sieve.

Hexandr'ia l-Monogynia. Allied to 

 Hyacinth.) 



Half-hardy bulb. Offset bulbs ; deep sandy 

 loam ; requires a little protection, or to be 

 taken up in winter.

PUTTY is a compound of boiled lin- 

 seed oil and whiting, but as it may be 

 bought in London at half-a-guinea per 

 cwt., it is scarcely worth while to make 

 it. One hundred weight is enough for 

 puttying about three hundred square 

 feet of glass. 



Old putty may be softened by apply- 

 ing to it rags dipped in a saturated 

 solution of caustic potash, leaving them 

 on for twelve hours ; or by rubbing a 

 hot iron along the putty. 



If the gardener does make putty, the 

 whiting should be well dried, and then 

 pounded and sifted till it becomes a 

 fine powder, and is quite free from grit. 

 The whiting, a little warm, should be 

 gradually added to the oil, and well- 

 mixed by means of a piece of stick, or 

 a spatula. When it is sufficiently stiff, 

 it should be well worked with the hand 

 on a table, and afterwards beaten on a 

 stone with a wooden mallet, till it be- 

 comes a soft, smooth, tenacious mass. 

 A ball of putty when left some days 

 becomes somewhat hard, but may be 

 easily softened by beating. 



PYCNO'STACHYS. (Frompyknos, dense, 

 and stachys, a spike ; dense flower- 

 spikes. Nat. ord., Labiates [Lamia-

 spcrmia.)

PYRE'THRUM. Feverfew. (Frompyr, 

 fire ; alluding to its acrid roots. Nat, 

 ord., Composites [Asteracea?] . Linn., 

 19-Syngenesia 2-Superflua.) 



All white-flowered, except where otherwise 

 mentioned. Hardy kinds, divisions, and seeds, 

 and common garden soil ; greenhouse kinds, by 

 cuttings under a hand-light, in sandy light soil ; 

 sandy fibry loam, and leaf-mould ; half-shrubby 

 kinds, such as foeniculatitrn, will not only do 

 well in cold greenhouses, but will probably 

 answer for the bottom of conservative walls.
