Piptospatha 



( 208 ) 



Pitcairnia 



Principal Species and its Variety : 



nepalensis, 8' to 10', spr., nepaleusis). Evergreen 



yel. (y. Baptisia Laburnum. 



aureus, bark striped 



gru., yel. 

 Other Species : 



tomeutosus, close to nepalensis, but clothed with 

 silky hair. 



PIPTOSPATHA. 



Stove herbaceous perennials (ord. Aroidese). 

 Propagated by division of the rootstock and by 

 seeds. Soil, loam two parts, leaf mould and peat 

 one part each, and sand. The drainage and water 

 supply must be liberal, and the plants revel in heat 

 and atmospheric moisture. 



Principal Species : 



Hidleyi, Je., st., spathe grn., pk. above, Ivs. 6" to 

 8" long, 2" broad, grn., yel. blotched. 



Other Species : 



insignis, sum., st., spathe wh., flushed pk., Ivs. 

 6" long, lance shaped, grn., leathery. 



PIQUERIA. 



Greenhouse and hardy shrubs and herbs (ord. 

 Compositse), of no garden value. 



PISCIDI A. (FISH POISON TREE, JAMAICA 

 DOGWOOD.) 



The only species (ord. Leguminoste) is a stove 

 evergreen tree. Propagated by cuttings of half- 

 ripened shoots in sand, in a close frame, with 

 bottom heat. Soil, sandy loam. It has no garden 

 value, but is of interest from the fact that in the 

 West Indies the leaves, bark, and twigs (bruised) 

 are thrown into the water to intoxicate fish which 

 it is desired to catch. Hence the popular name 

 Fish Poison Tree. 



Only Species : 



Erythrina, 80', My., st., wh., red. 



PISONIA (si/n. CALPIDIA, CEODES, COLU- 

 MELLA, PALLAVIA, and TOBBUBIA). 



Stove and greenhouse trees and shrubs (ord. 

 Nyctaginea;), some of them \)f sub-scandent habit ; 

 of no special garden value. Propagated by cuttings 

 in sandy soil, in a close case, with bottom heat. 

 Soil, loam three parts, leaf mould one part, and 

 sand. 



Principal Species : 



aculeata, 10', Mch., grh. grandis, 10', Mch., grh., 

 climbing shr., grn. grn. (syn. inermis). 



West Indian Cockspur. obtusata, 4', Ap., st. shr., 

 grn. 



PISTACIA. 



A small genus of dwarf, hardy or half-hardy 

 trees (ord. Anacardiaceas). Lentiscus yields the 

 drug mastic, and from Terebinthus is obtained the 

 Chian or Cyprus turpentine. Incisions are made 

 in the trunk, and the exuding liquor is caught. 

 Propagation is by layers and cuttings. Soil, a 

 deep, rather rich, sandy loam. The species under- 

 mentioned should be given the protection of a wall, 

 and a little covering during spells of very cold 

 weather. Even with these provisions they are not 

 safe except in very favoured localities.

 Other Species :

PISTIA (gym. APIOSPER.MUM, LIMNONESIS. 

 and ZALA). 



The only species (ord. Aroideae) is a curious and 

 pretty little floating stove aquatic, with bright, 

 Pea-green leaves about 2" long. The flowers are 

 very small, green, and quite inconspicuous. Propa- 

 gation, by offsets. 



Only Species : 



Stratiotes, 1" to 3", Ivs. bright Pea grn., flowers 

 grn., very small. Tropical Duckweed, Water 

 Lettuce. 



PISUM. (GARDEN PEA.) 



This genus is of great importance, although it 



contains only two species (ord. Leguminosne). 



Sativum is the parent of the garden Peas, which 



see. Elatius may be treated like the Lathyruses ; 



it is of little value. 

 Only Species : 



elatius, Je., Sep., hdy. former, humile (Dwarf 



ami. cl., pale red, wings Pea), saccharatum 



dark pur. (Sugar Pea), and um- 



sativum, Je., Sep., hdy. bellatum (Crown Pea) 



ann. cl., wh. or red. are some of the most 



There are many vars. distinct. Cultivated or 

 and sub-vars. Of the Garden Pea. 



PITCAIRNIA. 



A large genus (ord. Bromeliaceas) of stove 

 perennial herbs or shrubs, many of them with spiny 

 leaves. Some of the species are of considerable 

 beauty. All are very easy to grow, a high tempera- 

 ture and plenty of water while they are making 

 growth being the chief necessities. (For other 

 cultural details, see yKcHMEA and 13ILLBERGIA.) 

 Principal Species : 



[NOTE. All need a stove temperature, and all 

 are perennial.]
