The roots may be taken up as wanted 

 in September, but they do not attain ma- 

 turity till October, which is intimated by 

 the decay of the leaves. 



In November, part of the crop may be 

 taken up, and, the tops being cut close 

 off, layed in alternate layers with sand, 

 for use in frosty weather. The remainder 

 may be left in the ground, and taken up 

 as required, as they are never injured by 

 the most intense frost, but, on the con- 

 trary, are rendered sweeter. In February 

 or March, however, any remaining must 

 be taken up, otherwise they will vegetate. 

 Being preserved in sand, they continue 

 good until the end of April or May. 



To obtain Seed. Some of the finest 

 roots are best allowed to remain where 

 grown ; or else, being taken up in Fe- 

 bruary, planted in a situation open, but 

 sheltered from violent winds. If of ne- 

 cessity some of those are employed which 

 have been preserved in sand, such should 

 be selected as have not had their tops cut 

 off very close. 



In dry weather water plentifully twice 

 a week. At the end of August the seed is 

 usually ripe; the umbels may then be cut, 

 and when thoroughly dried on cloths, the 

 seed beaten out and stored. 



Seed should never be employed that is 

 more than a twelvemonth old. 



PARTERRE is synonymous with our 

 English name Flower Garden. 



PARTING the roots is a mode of propa- 

 gation available with some plants ; and 

 where a large increase of an individual 

 specimen by this mode is desired, its 

 flower-stems should be removed as fast 

 as they are produced. This makes the 

 plant stool, for whatever prevents the 

 formation of seed, promotes the de- 

 velopment of root.

 cuttings under a hand-light, in summer ; should 

 have a dry, warm spot, or the protection of a 

 frame, in winter.

Greenhouse evergreens, white-flowered, and 



from the Cape of Good Hope, except where other* 

 wise mentioned. Cuttings of the young shoots, 

 half-ripe, in sand, under a glass, in April or May ; 

 sandy peat, with a few nodules of fibry loam. 

 Winter temp., 40 to 48 ; summer, a rather shady 

 place after the wood is ripe. P.filifo'rmis might 

 be tried against a conservative wall.

 PASSIFLO'RA. Passion-Flower. (From 



passio, suffering, and flos, a flower ; re- 

 ferring to the filaments, or rays, and other 

 parts, being likened to the circumstances 

 of Christ's crucifixion. Nat. ord., Pas- 

 sion worts [Passifloracese]. Linn., 16- 

 Monadelphia 2-Pentandria.} 



Cuttings of young wood, in almost any stage 

 during summer, in sand, under a bell-glass or 

 hand-light ; peat and loam, Cceru'lea and its va- 

 rieties are the hardiest. It not only flowers freely, 

 but ripens fruit against a wall round London. 

 Incarna'ta is a pretty thing, of semi-herbaceous 

 habit, which has also, in a few cases, been tried 

 against a wall. The shoots of the cceru'lea group 

 might easily be wrapped together, and defended in 

 winter by a mat. The fruit of many is very plea- 

 sant and refreshing to most palates. The edu'lis 

 fruits very freely in a stove, but the flower has no 

 great beauty ; it fruited a number of years with 

 us in a cool conservatory, but it died at last. We 

 found it hardier than the newest one, Billo'ttii. 

 The quadrangula'ris, to be fruited, must be 

 grown in a good, light situation, in a warm stove, 

 and be artificially impregnated. SeeGa.A.KA.m 'LLA.
