THE DICTIONARY OF GARDENING, 



Felliouia continued. 



P. Daveauana (Daveau's).* fl. green; females very minute; 

 males six to eight times larger ; perianths five-parted ; in- 

 florescence pedunculate, densely cymose. August. I. alternate, 

 stipulate, in. to 2in. long, oblique, roundish-elliptic or elliptic- 

 oblong, obtuse, dark bronzy-ohve-green, slightly tinted with 

 violet, or marked with a broad, central, irregular band of bright 

 green. Stems succulent. Cochin China, 1880. A charming 

 creeper. SYN. Begonia Daveauana. (I. H. n. s. 472.) 



P. D. viridls (green). 1. uniformly bright green, with whitish 

 blotches. Stem, as well as the petioles, midrib, and veins of the 

 leaves, sparsely hairy. 1882. 



P. pulchra (pretty).* I. alternate, petiolate, stipulate, obliquely 

 oblong, very obtuse, obliquely cordate at base; upper surface 

 dull blackish along the midrib and veins ; under surface pale, 

 and rather delicate purplish ; primary veins five on each side.

 Cochin China, 1882. Plant glabrous, except a few hairs on the 

 upper side of the petioles. (I. H. 479.) 



PELLITORY. See Pyrethmm Farthenium. 



PELONASTES. Included under Myriophyllum 

 (which see). 



PELORIA. " An irregular flower, become regular 

 by a monstrous development of complementary irregu- 

 larities " (Asa Gray). 



FELTANDRA (from pelte, a target, and aner, 

 andros, a stamen ; alluding to the shape of the stamens). 

 STNS. Lecontia, Renselaeria. OBD. Aroidece (Araceas). 

 A genus comprising only a couple of species of hardy, 

 marsh-loving, perennial herbs, with very slender rhizomes, 

 natives of North-eastern America. Spathe convolute, with 

 an elongated, persistent tube, and the margins of the 

 lamina undulated; spadix much shorter than the spathe, 

 slender, erect, cylindrical, almost entirely covered, 

 except at the top, with densely-crowded flowers. Leaves 

 sub-peltate, hastate, with very slender, dense nerves ; 

 petioles long, sheathing. P. virginica, the species best 

 known in gardens, must be grown, like Calla, in 

 shallow water, in a sunny, sheltered pond.

 ' upper portion of the 



spathe, ana stenie portion of flie spadix, rotting away after 



florescence, leaving the fleshy base firmly inclosing the globular 



cluster of fruit" (Asa Gray). June. I. lar 



reticulated next the margin, h. 1ft. 1759. 



FELTANTHERA. A synonym of Vallaris (which 

 tee). 



PELTARIA (from pelte, a small buckler ; alluding 

 to the form of the pods). OBD. Cruet/era. A genus 

 comprising three species of hardy, tall, glabrous, peren- 

 nial herbs, natives of South Europe, Asia Minor, Syria, 

 and Persia. Flowers white, sub-corymbose. Pods large; 

 fructiferous pedicels patent or recurved, filiform, ebrac- 

 teate. Leaves entire; cauline ones cordate-sagittate at 

 base. P. alliacea is a pretty little plant. It flourishes 

 in any light soil, and may be increased either by seeds, 

 or by division. 

 P. alliacea (Onion-scented).* fl., calyx equal ; petals entire. 



June. Pods flat, smooth. I., cauline ones sagittato-amplexicaul. 



h. 1ft. Eastern Europe, 1601. The plant emits a Garlic-like 



odour. (J. F. A. 123.) 



PELTATE. Target shaped ; 

 shield-like. A leaf is said to be 

 Peltate when the petiole is attached 

 to the lower surface instead of to 

 the margin. See Fig. 73. 



PELTATIFID. When a pel- 

 tate leaf is sub-divided. 



PELTINERVED. Eadiately- 

 ncrved. When the nerves of a 

 leaf are disposed in a peltate man- 

 ner. 



P. virginica (Virginian). Arrow Arum. fl. 

 long and tapering spadix throughout; " 

 spathe, and sterile portion of the spadix, rotting away after 

 florescence, leaving the fleshy base firmly inclosing the globular 

 cluster of fruit" (Asa Gray). June. I. large, pointed; nerves 



PELTOPHORUM (from pelte, 

 a small shield, and phoreo, to bear ; 

 in reference to the shape of the

stigma). ORD. Leguminosce. A genus of about half-a- 

 dozen species of tall, unarmed, stove trees, of which two 

 or three are tropical American, one is found in South- 

 eastern Africa, and two in the Indian Archipelago and 

 tropical Australia. Flowers yellow, racemose ; calyx seg- 

 ments five, imbricated ; petals five, orbicular, spread- 

 ing, much-imbricated; racemes paniculate, at the tips 

 of the branches. Pods oblong-lanceolate, rarely elongated, 

 flat-compressed, indehiscent. Leaves bipinnate; leaflets 

 small, numerous. P. Linnoei is described in this work as 

 CoBsalpinia brasiliensis. 



PELTOSTIGMA (from pelte, a buckler, and stigma ; 

 alluding to the protuberance of the stigma). SYN. Pachy* 

 stigma. OED. Rutacece. A monotypic genus. The species 

 is a very glabrous, low, fragrant, stove, evergreen tree. 

 It thrives in sandy loam and fibry peat. Propagated 

 by cuttings, inserted under a bell glass, in heat. 



P. pteleoldes (Ptelea-like). fl. white, rather large, puberulous 

 outside, disposed in fastigiate, long-stalked, few-flowered, tricho- 

 tomous cymes ; sepals three or four, free, deciduous, two outer 

 ones smaller ; petals four, broadly obovate, concave ; pedicels 

 with leafy bracts. February. I. alternate, trifoliolate ; leaflets 

 elliptic, sub-entire, gland-dotted. Jamaica, 1844. 



PELVIFORM. Shallowly cup-shaped ; basin-like. 



PEMPHIGUS. A genus of Aphides, distinguished 

 from the more frequently observed forms by the six- 

 jointed, short antennae, the absence of honey tubes near 

 the end of the body, and the front wings having all the 

 veins that end on the hind margin unbranched. The body 

 is generally more or less bedecked with a woolly secre- 

 tion, especially near the tip. Several species are found 

 in Britain. Of these, some form galls on Elms, and on 

 Poplars (e.g., P. bursarius on leafstalks of the Black 

 Poplar), while most of them feed on the roots of plants, 

 especially of Composite and of grasses. The latter species 

 may be found in small companies, in cavities, loosely lined 

 with the white secretion. The insects prefer light, sandy 

 soils. P. lactucarius and P. fuscifrons both injure garden 

 Lettuces considerably at times. SSe Lettuce. M. Lich- 

 tenstein, of MontpelUer, has brought forward strong argu- 

 ments in support of the belief that the gall-makers pass 

 through a cycle, in which a generation of gall-makers 

 on trees alternates with one feeding on the roots of 

 herbaceous plants ; and he has proved that this occurs 

 with the allied Tetraneura Ulmi, the maker of the erect 

 galls (about the size of small Cherry-stones), common on 

 Elm leaves in various English localities. This species of 

 Aphis he has traced from the Elm galls to roots of Maize, 

 and of Cynodon dactylon, and vice versti. 



FENJBA (named after P. Pena, author, with Lobel, 

 of " Adversaria Botanica," 1570). OBD. Penasacece. A 

 small genus (nine species) of very dwarf-growing, green- 

 house, evergreen, much-branched, densely leafy shrubs, 

 natives of South Africa. Flowers yellow or reddish, soli- 

 tary, axillary, at the ends of the branches, forming leafy 

 spikes ; perianth tube oblong-cylindrical or ovoid, the lobes 

 of the limb valvate. Leaves opposite, sessile, entire, 

 coriaceous; floral ones more conformed, or broader and 

 shorter, than the cauline ones. It is doubtful whether 

 those species described below are still in cultivation. 

 They require a sandy-peat soil. Propagation may be 

 effected by cuttings, inserted in sand, under a glass. 

 P. mucronata (mucronate). /. and bracts yellow or purplish. 



June. I., lower ones ovate, acute, caducous ; middle ones ovate, 



acuminate, broadly sub-cordate at base ; uppermost ones reduced 



to bracts, h. 2ft. 1787. (L. B. C. 1770.) 

 P. myrtoldes (Myrtle-like), fl. red. June. I. sessile, ovate or 



ovate-elliptic, obtuse, flat. h. 2ft. 1816. 

 P. squamosa (scaly). A synonym of Sarcoeolla squamosa. 



PEN.2EACE.2E. A small natural order of much- 

 branched shrubs, confined to South Africa, and of doubtful 

 affinity with any other order. Flowers hermaphrodite, 

 regular, solitary in the upper axils, aub-sessilo ; perianth
