 strongly and disagreeably scented. Nat. ord. Rubiaceae.) 



A small, evergreen shrubby plant. Divisions ; cuttings 

 in sand under a hand-light. Light, well-drained soil.

 a botanist of Vienna. Nat. ord. Celastraceae.) 



Greenhouse shrubs. Cuttings in sand under a bell-

PUTTY is a compound of boiled linseed-oil and whiting, 

 but as it may be bought in London at half a guinea per 

 cwt., it is scarcely worth while to aiake it. One cwt. 

 is enough for puttying about three hundred square feet of 

 glass. 



Old putty may be softened by applying 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 becomes a soft, smooth, 

 tenacious mass. A ball of putty, when left some days, 

 becomes somewhat hard, but may be easily softened by 

 beating.

PYGtfTRA BUCEPHALA. Buff-tip Moth. This moth 

 is from 2 to 3 inches across the opened fore-winus, which 

 are silvery-grey, crossed by a slender black line, and 

 preceded by a red one near the base of the wings, several 

 dusky bars in the middle, and with a large oval cream- 

 coloured patch, enclosing some small buff spots ; edged 

 with a curved red line, preceded by a black one ; the 

 edges of the wings varied, black, grey, and tawny red. 

 Hind-wings whitish ; body buff, dark brown at the sides, 

 and behind. The caterpillars are yellow, with black 

 legs, and several rows of interrupted black stripes. 

 Sometimes the green and black most prevail, so that the 

 yellow seems to constitute the bands. They are found 

 whilst young, thirty or forty together, on the leaves of 

 the filbert during August and September, but also on the 

 leaves of the elm, oak, &c. The chrysalis is found in the 

 earth ; it has two small points at its tail. The cater- 

 pillars are so large and conspicuous that hand-picking is 

 an easy and quick remedy. 



PYRENACA'NTHA. (From pur en, the stone of a 

 fruit, and akantha, a thorn. Nat. ord. Olacacea?.) 



A stove climber, with a fleshy rootstock more than 

 3 feet across. Cuttings of short side-shoots in sand, 

 placed in a close case, with bottom-heat. Fibrous loam, 

 leaf-mould, broken bricks, and sand. 

 P. malvifo'lia (mallow-leaved). 6-10. Greenish. Fruits 

 orange-red. E. Trop. Africa. 1906.
