PIP, in floriculture, is a single corolla 

 or flower, where several grow upon a 

 common stem, as in the Polyanthus 

 and Auricula. The pips thus growing 

 together are described as a Truss. 



PI'PEE. Pepper. (From pepto, to 

 digest; referring to the stimulating- 

 power. Nat. ord., Peppenvorts [Pipera- 

 ceee]. Linn., 2-Diandria 3-Triandria.) 



Stove evergreens. Cuttings of half-ripened 

 wood, under a bell-glass, in sandy soil, in heat ; 

 also by suckers from the bottom of the plant. 

 Winter temp., 50 to 60; summer, 60 to 80. 

 The genus contains the pepper plant, and the 

 Betle, of which the leaf is chewed in India as 

 much as tobacco is in the west.

PIPEEIDGE, the Barberry. 



PIPES for heating horticultural struc- 

 tures are preferably made of cast iron, 

 painted black. Earthenware has been 

 recommended for the purpose, but they 

 are so much more liable to breakage 

 and leakage, as to outweigh any original 

 saving in the cost. For draining, earthen 

 pipes with a bore an inch in diameter 

 are the best. 



To ascertain by the above Table the 

 quantity of pipe which will heat one 

 thousand cubic feet of air per minute, 

 find, in the first column, the tempera- 

 ture corresponding to that of the ex- 

 ternal air, and in one of the other 

 columns find the temperature of the 

 room ; then, in this latter column, and 

 on the line which corresponds with the 

 external temperature, the required 

 number of feet of pipe will be found. 



PIPEWOET. Erioca'ulon. 



PIPING, a mode of propagating the 

 Carnation, Picotee, and Pink, is only 

 another word for a cutting. Some 

 persons pull off the pipings from the 

 plant, and stick them in without more 

 ado, but this is a slovenly way ; besides, 

 in pulling off the pipings, the main 

 stem of the plant is materially injured, 

 and often destroyed. The more correct 

 way is, with a sharp knife, to cut off 

 the side-shoot close to the stem, without 

 injuring it, leaving a sufficient number 

 of shoots to preserve the health of the 

 plant. Take off one kind at once, 

 making the proper number or tally at
