PUTRANJIYA. A large timber-tree, with 



a white close-grained very hard wood, from 



I the mountainous districts of Central and 



i Peninsular India,; forming a genus of 



Euphorbiacece closely allied to Phyllanthus, 

 and chiefly distinguished by the fruit.which 

 is always one-seeded only, although de- 

 rived from a three-celled ovary with two 

 ovules in each cell. 



PUTTERLICKIA. A genus of Celastra- 

 ceo3 founded on the Celastrus pyracanthus 

 and an allied species, both from the Cape 

 Colony, which differ from the other species 

 of Celastrus in having about six ovules in 

 each cell of the ovary instead of two only. 

 The genus is not adopted by all botanists.

PUYA. This is the same as Pourretia 

 of Ruiz and Pavon, and is a tropical and 

 southern subtropical genus of Bromelia- 

 cew, the species of which have simple 

 sometimes almost arboreous leafy stems, 

 with narrow spiny leaves, and simple or 

 compound bracteated flower-spikes. Its 

 flowers have a six-parted perianth, with 

 the divisions in two series, the outer caly- 

 cine and the inner petaloid. [A. S.] 



PUYA. Bohmeria Puya. 



PYA. A name used in the Sandwich 

 Islands for Tacca oceanica. 



PYCNANTHEMUM. The generic name 

 of the Mountain Mints of the United 

 States. These are closely allied to our own 

 mints, but have evidently two-lipped co- 

 rollas, in common with the great mass of 

 the Labiate, while in Mentha the corolla 

 has an almost equally four-lobed border. 

 About a dozen species are known, peren- 

 nial herbs with erect four-angled stems, 

 furnished with opposite mint-like or hys- 

 sop-like leaves smelling like those of 

 spearmint or pennyroyal, and small white 

 or lilac flowers disposed in terminal dense 

 cymose bracted heads. To this the generic 

 name (derived from the Greek pyknos 

 'dense,' and anthemon 'a flower') alludes. 

 The chief features of the genus are the 

 shortly tubular two-lipped and ten to thir- 

 teen-nerved calyx, naked in the throat ; the 

 two-lipped corolla; and the four perfect 

 stamens. [A. A. B.J 



PYCNIDIA. Many species of Splmria 

 and allied genera have a second kind of 

 fruit resembling in some measure the 

 perithecia, but instead of producing asci 

 generating naked spores. These organs are 

 called pycnidia to distinguish them from 

 perithecia. In Erysiphe two kinds of 

 pycnidia are sometimes present, the one 

 like the normal fruit, the other produced 

 by a transformation of one or more cells 

 of the short chains of spores produced on 

 the white spawn. Pycnidia require to be 

 cautiously distinguished from spermogo- 

 nia, and indeed are in many cases to be re- 

 cognised only by observing whether the 

 granules to which they give rise are capa- 

 ble of germination. [M. J. B.] 



PYCNOCOMA. A genus of Euphorbiacem
