of black in the centre ; it is very showy 
among shrubs in a wide border; P. cayi- 
bricum is a pretty dwarf species with 
bright yellow flowers, also a perennial, 
and the double variegated varieties of 
P. P/iceas, commonly known as Dutch 
poppies; the seed of these should be 
planted in March where they are to 
remain, thinning the plants afterwards 
to a distance of about a foot from each 
other. Opium is obtained from P. som- 
nifera , and the seed of a variety of this, 
called the black poppy, is sold as maw¬ 
seed for birds and medicinal purposes. 
PAPHINIA (Lindley.) Nat. Ord. 
Orchidacece. The only species known, 
P. cristata , was formerly included in the 
genus Maxillaria, but on a revision of 
that genus was separated by Dr. Lindley 
as above. It is a splendid plant bearing 
richly coloured flowers, and is rather dif¬ 
ficult to cultivate. The best manner of 
managing it is to pot it in a mixture of 
rotten wood and moss, elevating it con¬ 
siderably above the rim of the pot, allow¬ 
ing it to stand in the warmest part of 
the stove, and being careful to avoid 
over-watering at any time; it delight^ in 
a high moist temperature while growing, 
but should be kept nearly dry when at 
rest. The young shoots which spring 
from the base of the pseudo-bulbs are 
very impatient of stagnated moisture, 
and should therefore be kept clear of 
the surrounding mould. 
PASSIELORA (Linn.) Nat. Ord. 
Pccssifloracece. All the passion-flowers 
are handsome, fast growing, and free- 
flowering climbers. Erom among them 
may be^ selected ornaments for either 
stove, greenhouse, or the open air. They 
delight in rich loamy soil, and should 
have plenty of room as their branches 
extend over a large space. In the au¬ 
tumn of each year they should be cut 
back to keep them in the requisite 
bounds, but not at any other time. P. 
coendea and two varieties of it, Colvillii 
and glaucophylla, are sufficiently hardy 
to withstand the rigours of our climate. 
P. coerulea, racemosa, and incarnata are 
the only two which can be said to do 
well in the greenhouse; the first is a 
really beautiful object, perhaps the finest 
of the whole genus, and the other is 
pretty, though not equal to some of its 
congeners. Among those which grace 
the stove through the greater part of the 
summer months, we prefer the following: 
alata, edulis (for its fruit), Kermesina , 
Loudonii, quadrangidaris, and princeps. 
PAVETTA (Linn.) Nat. Ord. Cin- 
chonacere. Pavetta Caffra is a partieu- 
arly noble greenhouse shrub, with ample 
deep green foliage, surmounted with 
bunches of lovely pure white flowers, 
mud is well deserving attention as a 
C£ show plant.” There are two other 
species somewhat inferior to this : they 
are natives of the East Indies, while 
the first mentioned is from the Cape 
of Good Hope. All of them succeed 
when potted in sandy peat and loam, 
allowing them the ordinary treatment of 
greenhouse plants. 
PELAHGONIUM ( L’Heritier. ) 
Nat. Order Geraniaceae. If this genus 
be viewed either in a botanical sense or 
as an ornament to our gardens, it _ is 
alike important: the number of species 
and varieties included in it is astonish¬ 
ingly great, embracing an immense range 
of forms and colours, and every season 
adds to the number of the latter very 
considerably. Before proceeding to their 
culture it may be well to mention the 
division which has been made of this 
family of plants in Sweet’s monograph 
of the order Geraniacem, and which, 
now that the small flowering species 
composing the genera there formed are 
being drawn more prominently into no¬ 
tice, it becomes also essential to know 
something of their arrangement. With¬ 
out entering into the character of these 
divisions which our space will not allow, 
it is only necessary to say they are five : 
the type of the first, Campylia, is the 
well-known buckshorn-leaved species, 
C . coronopifolium ; the pretty tlnee-co- 
loured stork’s bill, P. tricolor, is that of 
the second division, Phymatanthus; the 
third, Ciconium, is expressed by the old 
horseshoe Geranium or Ciconium zonale, 
as it is now called; Jenkinsonia, a 
fourth group, is exemplified in the well- 
known coriander-leaved Pelargonium, 
J. coriandrifolia; while the parsley-
