in this country.

PLANK-PLANT. Sce Bossiea scolopendria. 
PLANT. An organised being endowed with life, and 
very occasionally with the power of motion (as in 
Insectivorous and Climbing Plants and in Zoospores). 
When complete they have a root, stem, and leaves, or 
less often a single leafy expansion, a series of cellules, or 
even a single cellule. Further, they are divided into 
flowering (Phanerogamons) and flowerless (Cryptogamons). 
The former have flowers and seeds ; but the latter depend 
for their reproduction upon minute one-celled spores. 
PLANTAGO. To the species described on p. 155, 
Vol. III., the following shonld be added : 
P. coriacea (leathery). The correct name of P. brasiliensis. 
P. lanceolata marginata (margined). (., stem crowned 
with a tuft of oblong-lanceolate leaves, spotted with white. 
t. bordered with white and marked with glaucous stripes, 
three- to five-ribbed, erect or spreading. France, 1889. An 
abnormal form; it may be increased by division.

P. uniflora (one-flowered). #., scape slender, as long as the 
leaves, one-flowered, hairy. /. few, 4in. to ljin. long, narrow- 
lanceolate, sinuate-toothed or entire, variegated, villous at 
base. Stems jin. high only. New Zealand, 1899. 
PLANT BUGS. Sve Insects—Heteroptera. 
PLASHING. This is really an intertwining of growths. 
When Thorn or other hedges become too tall or bare at 
the base, they are strengthened and made almost impene- 
trable to animals by bending down the growths and 
entting them about half-way throagh at the base, and 
twining them among stout stakes. These stakes are 
about 4ft. apart, and are known as live and dead stakes. 
The live stake is an upright growth cut off at the proper 
height in the fence, and the dead stake is one that is 
made and driven into the soil. 
PLASMODIOPHORA BRASSICZ. Sce Finger- 
and-Toe, Clubbing, or Anbury. 
PLASMOPARA VITICOLA. See Vine Fungi. 
PLATANUS. To the species, &c., described on 
p. 156, Vol. III., the following varieties should be added. 
According to the Kew list, P. acerifolia and P. cuneata 
now rank as species and not as forms of P. orientalis. 
P. acerifolia Siuttneri (Sittner’s).* 7. deeply cut, pale green, 
beautifully marbled and striped with creamy-white. A hardy 
and vigorous variety, with constant variegation. 
P. occidentalis cucullata (hooded). J. small, roundish, 
nearly entire or slightly lobulate, somewhat cucullate. 1877. 
A curious variety. ‘There are several variegated forms of 
P. occidentalis, that known as P. 0. argenteo-variegatis being 
very ornamental. 
PLATYCAPNOS. 
see). 
PLATYCERIUM. Elk’s-horn and Stag’s-horn Ferns. 
With the exception of P. alcicorne, which thrives best 
in an ordinary greenhouse temperature, all Phatyceriams 
require stove treatment. They succeed best and become 
most effective when planted in the fork of an ordinary 
tree-branch or in an artificial wall-pocket made of virgin 
cork. P. alcicorne also has a most pleasing appearance 
when grown as a basket-plant, as its roots, which usually 
produce young plants on their surface, soon make a 
perfect ball, imparting a singular effect, growing as it 
does in all directions—sideways, head downwards, &c.— 
with equal vigour. The best compost is a mixture, in 
about equal parts, of rough, fibrous peat and sphagnum. 
The plants are particularly fond of strong light, and 
should receive water at the roots with moderation. The 
best way to keep them in good condition “in that respect 
is to soak them thoroughly, and then to wait until the 
foliage begins to droop and to present a soft, withered 
aspect before soaking them again. 
Platyceriums are usually propagated by means of young 
plants produced from the adventitious buds on their 
roots. P. grande, however, has never been known to 
produce any, and consequently it must be propagated by 
means of spores; this method, though somewhat slow, 
is also resorted to for other species when required in 
great quantities. 2
