PIERIS. 



A genus of butterflies whose caterpillars are 

 destructive of the Brassica tribe. Brassicse, the 

 Large White Cabbage Butterfly, is the most 

 common. The first brood is on the wing from May 

 to July, and the second from September to October. 

 The eggs, which are bright yellow, are laid singly, 

 and affixed to the leaves of the Cabbages. 



The Small White Butterfly, Rapse, has also two 

 broods in the season, one in April and one in July, 

 and the caterpillars are full-fed in about three 

 weeks from the time of hatching; they are 

 generally green. (For remedies, see CABBAGE 

 ENEMIES.) 



PIGAFETTA. 



The three species of this genus of stove Palms 

 (ord. Palmao) are tall, noble-looking plants, with 

 spiny trunks of very hard wood. The leaves are- 

 large and elegant in their droop, but the plants are 

 rarely cultivated. Propagation, by seeds. Soil, 

 good loam. Firm potting is advisable. 



Principal Species : 



elata, tall, st., Ivs. like those of Cocos, petioles 

 spiny (syns. Hyospathe elata of gardens and Me- 

 troxylon elatum). 



PIL.EA (syns. ABIKE ancl DEBREUILIA. 

 STINGLESS NETTLE.) 



There are many species in this genus (ord. 

 Urticacese), but none of them appeal to the 

 gardener save muscosa (syn. microphylla), the 

 Artillery Plant. This is in great request'for filling 

 small vases for dinner table and dwelling room 

 decoration. The finely cut, but fleshy, light green 

 stems and small leaves, with the reddish flowers 

 and fruits, are very ornamental, and the plants 

 stand fairly well in summer. Propagation, by 

 cuttings in sandy soil, in a warm, close pit with 

 bottom heat. Seeds and divisions are likewise 

 available. Six cuttings may be placed in a 4" pot 

 and the plants nsed for decoration. No potting is 

 required, but a constant supply of cuttings should

be kept up to furnish decorative material. Larger 

 specimens may be grown if desired, but the small 

 ones are far more useful. Established plants need 

 plenty of heat and water, and revel in regular 

 syringings. Soil, loam, leaf mould, and sand. 



Principal Species : 



muscosa, 4'' to (J", sum., st., flowers small, 

 reddish br., steins much branched (syn. micro- 

 phylla of Liebm.). Artillery or Pistol Plant. 



PILEANTHUS. 



A small genus of Heath-like shrubs (ord. 

 Myrtacea;), all Australian evergreens, and needing 

 a greenhouse temperature. Propagation, by 3" 

 cuttings of the young shoots in spring, in sand, 

 under a bell-glass. Soil, loam and peat in equal 

 parts, and one-sixth sand. 



Principal Species: 



Limacis, 2' to 3', Ap., wh. 



PILOCARPUS. 



Stove shrubs with green or purple flowers (ord. 

 Rutacere), of little worth to the gardener. Jabo- 

 randi is one of the plants that furnish the Jabo- 

 randi of commerce. 



PILOCEREUS. 



A small genus of succulent plants (ord. Cactere), 

 of singular appearance. They are included in the 

 larger genus Cereus, but have been kept distinct 

 for garden purposes. Most of the species are of 

 easy cultivation in a greenhouse temperature, and 

 may be treated exactly like the other cool house 

 Cereuses. The plants very rarely flower, but the 

 spines and the long white hairs constitute the 

 chief attraction. Young plants of senilis are more 

 woolly than old ones. A greenhouse temperature 

 is required, except where otherwise stated. 



Principal Species : 



senilis, 1' to 3', stem cylindrical, fluted, 30 to 40 

 furrows, spines wh., hairs long, wh. The stems are 

 tender and fleshy when young. Old Man Cactus. 



Other Species : 

 Brunuowii, stem erect, bright grn., hair long, 



cylindrical, hairs long, wh., cottony. 



wh. fossulntiis, stem club 



cclsianus, stems colnm- shaped, 10 to 12 angled,

Dantwit/ii, stem oblong, spines straw yel., whole 



plant felted. 



PILULARIA. (PILLWORT.) 



Obscure little aquatics (ord. Marsileaceaj), wort h- 

 less to the gardener, but interesting to the botanist 

 us link plants. Globulifera is common in damp 

 lidti.-h meadows. It has bright green leaves from 

 1'' to 4" long. The capsules in which the spores 

 are borne are like pills. 



PIMELEA (syns. BAXKSIA of FOESTEB, 

 and COOKIA). 



Description. Greenhouse trees, shrnbs,and herbs 

 (ord. Thymelicacea;), natives of Australia and New- 

 Zealand.
