the outer segments of the perianth, and 

 attached to the short stalk supporting the 

 OTary, which is one-celled with three pa- 

 rietal placenta?. The seeds are provided 

 with a cup-shaped arillus, which is de- 

 scribed as being eaten in Madagascar, and 

 as having a very sweet taste. [M. T. M.] 



PARROTIA. A genus of Hamamelida- 

 cece, represented by P. persica {Hamamelis 

 persica), a tree inhabiting Northern Persia 

 and the Caucasus, and yielding a very hard 

 timber. The leaves are alternate, oval, acu- 

 minate, and towards the point furnished 

 with small teeth. The tube of the calyx is 

 bell-shaped, and the border divided into 

 five or seven lobes; the corolla is want- 

 ing ; the stamens are from live to seven, 

 the styles two ; and the capsule is two-cell- 

 ed, each cell containing one seed. [B. S.] 



PARROTS-BILL. A New Zealand name 

 for Clianthus puniceus. 



PARROT- WEED. A West Indian name 

 for Boccmiiafrutescens. 



PARRYA. A genus of Cruciferce, con- 

 sisting of perennial herbs from the Arctic 

 regions, with the leaves chiefly radical, 

 fleshy, entire or toothed, and the flowers 

 rose-coloured or purple. The pod is broadly 

 linear or oblong, the valves veined, and 

 j the seeds in two rows, margined. [J.T. S.J

PARSONSIA. A genus of Apocynacece, 

 having a funnel-shaped corolla, the border 

 of which is five-parted and bent back ; the 

 stamens inserted near the base of the tube ; 

 and the style single, dilated at the apex. 

 The genus has representatives in the East 

 and West Indies, and in Australia ; and 

 consists of twining shrubs with opposite 

 leaves. The name was given in honour of 

 Dr. Parsons, a physician and writer on 

 Natural History. [G. D.] 



PARTED, PARTITE. Divided into a 

 determinate number of segments, which 



extend nearly to the base of the part to 

 which they belong. Thus, bipartite is parted 

 in two, tripartite in three, and so on. 



PARTHENIUM. A genus of Composites 

 of the tribe Helianthece, consisting of herbs 

 or undershrubs, with alternate leaves, and 

 small nearly globular heads of white flow- 

 ers in a terminal flat corymb. The invo- 

 lucre has two rows of broad bracts, and 

 contains five shortly obcordate female flo- 

 rets in the ray, and several tubular male 

 ones in the disk ; the receptacle has mem- 

 branous scales. The achenes are flattened 

 from front to back, with a callous margin, 

 and a pappus of two small awnlike or broad 

 scales. There are six species known, na- 

 tives of Northern or tropical America, 

 among which P. Hysterophorus with twice 

 pinnate leaves, common in the warmer | 

 parts of America, has been introduced into 

 our botanical gardens. 



PARTIALIS. A secondary division ; as 

 in umbellifers, where the umbels of the 

 second degree bear this name. 



PARTIBLE. Capable of being divided, 

 but not dividing spontaneously. 



PARTITE. Divided nearly to the base : 

 thus partitions are the deepest divisions 

 into which a leaf can be cut without be- 

 coming compound. 



PARTITIONED. Divided by internal 

 horizontal partitions into chambers. 



PARTRIDGE-BERRY. Gaultheria pro- 

 cumbens ; also an American name for Mit- 

 chella. 



PARTRIDGE-WOOD. The wood of cer- 

 tain South American and West Indian trees, 

 one of which is supposed to be Andira 

 inermis. 



PARVATIA. A genus of Lardizabalacea?, 

 closely allied to Stauntonia, from which it 

 is distinguished by its flowers having six 

 lance-shaped petals, much smaller than the 

 six sepals. The stamens of the male flowers 

 are united into a tube ; those of the female 

 are free and barren, the latter containing, 

 also, three egg-shaped ovaries terminated 

 by oblong sharp-pointed styles. The only 

 species, P. Brunoniana, is a tall climbing 

 shrub, with long-stalked trifoliate leaves, 

 and axillary racemes of small greenish 

 flowers ; it is a native of the Khasia 

 mountains. [A. SJ 



PASCALIA. A Chilian genus of Compo- 



sitce, related to Heliopsis, and represented 

 by a single species, P. glauca, an erect pe- 

 rennial herb, Avith a resinous smell, and 

 furnished with trinerved leaves, a single 

 yellow-rayed flower-head nearly an inch 

 across terminating each branch. The strap- 

 shaped and female ray-florets have three- 

 sided achenes ; and in the tubular and per- 

 fect disk-florets the achenes are four-sided, 

 surmounted by a minutely-toothed pappus 

 crown, and nearly enveloped in the chaffy 

 scales of the receptacle. The plant culti- 

 vated in England as P. glauca is evidently
