PASTINACA (name from the Latin pastus, food). 

 U mbettiferse . About a dozen species of tall herbs native 

 to Eu. and Asia, by Bentham & Hooker united with 

 the genus Peucedanum, but by Engler & Prantl and 

 others kept distinct. It is distinguished from Heracleum 

 and Peucedanum by technical characters of the fr. Fls. 

 yellow, small, in compound naked umbels; calyx-teeth 

 obsolete. Pastinaca is known to horticulturists in the 

 parsnip (which see), P. saliva, Linn. It is a native of 

 Eu., but is now grown in cool-temperate countries for 

 its large edible root. In deep moist soil and a cool cli- 

 mate, the roots become 18-20 in. long and 4 in. or more 

 in diam. at the crown. It was cult, before the Christian 

 era. It has run wild from gardens, often becoming a 

 bad weed in neglected fields and on roadsides. P. 

 satira is a robust biennial, sending up a grooved st. 

 (which becomes hollow) 3-5 ft.: Ivs. odd-pinnate, with 

 3-4 pairs of sessile ovate or oblong sharp-toothed and 

 notched Ifts. the terminal 1ft. 3-lobed: fr. ("seed") thin 

 and flat, retaining its vitality only a year or two. When 

 run wild, it loses its thick root, and sometimes it 

 becomes annual. L H B 



PATERSONIA (named for William Paterson, an 

 English traveler). Iridaceae. Perennial herbs with 

 short creeping rhizomes and rigid linear Ivs. grouped in 

 a distichous basal rosette: perianth-tube elongated; 

 outer segms. obovate-cuneate, spreading; inner minute, 

 erect: ovary clavate, 3-celled; ovules many, super- 

 posed; seeds angled by pressure. About 19 species, all 

 natives of Austral/ P. occidentalis, R. Br. (P. 

 sapphirma, Lindl.). Sts. very short: Ivs. rigid, longest 

 often over 1 ft.: scapes longer or shorter than Ivs., 

 dilated and stria te under the spike; outer bracts 1% 

 in. long or more, prominently or rather obscurely 

 keeled, inner bracts membranaceous, sometimes pubes- 

 cent on the keel: fls. usually numerous; perianth-tube 

 more or less villous; outer segms. often fully 1 in. long, 

 broad and very obtuse, rich blue; inner segms. minute, 

 ovate or lanceolate; style articulate near the base of 

 the anthers. H.U. 1, p. 324. 



PATRfNIA (E. L. Patrin. 1742-1814, French traveler 

 in Siberia). Vcderiandcex. Yellow- or white-flowered 

 valerian-like hardy herbaceous perennials, a foot or so 

 high, blooming in early summer; resemble Valeriana 

 and Fedia. 



Glabrous or loosely villous herbs: Ivs. once or twice 

 pinnatifid or pinnatisect, the radical ones rarely entire: 

 cymes corymbose-panieled ; bracts narrow, free, but 

 sometimes appendaged with a large 2-nerved and 

 netted-veined bracteole which is appressed to the fr.: 

 calyx with a small erect or spreading somewhat dentate 

 limb; corolla-tube very short; lobes 5, spreading; 



158 



stamens usually 4; style nearly entire at apex: sterile 

 locules of the fr. nearly as large or larger than the fertile 

 ones. About 15 species in extratropical Asia; little 

 planted. They are of easy cult, in damp or shady 

 places; bloom May to July. They are grown either in 

 borders or in rockwork. Prop, by division of the roots 

 and also by seeds. 



scabiosaefolia, Fisch. St. glabrous: radical Ivs. ovate 

 or oblong, incised-serrate and lyrate; cauline Ivs. pin- 

 natifid, the lobes lanceolate-linear, acute, terminal one 

 longest: fls. yellow; corymb loosely subpaniculate : fr. 

 3-cornered. Dahuria. L.B.C. 14:1340. 



villdsa, Juss. Coarse, 2-3 ft.: radical Ivs. villous, 

 petiplate, auricled; cauline Ivs. sessile, dentate: corymb 

 panicled, bearing white fls. Japan. 



triloba, Miq. (P. palmate, Maxim.). Sts. erect, red- 

 dish, 8-16 in., simple below, pubescent at nodes and 

 also on peduncles: Ivs. cordate in outline, deeply 

 palmately 3-5-lobed or the uppermost little if any lobed, 

 margins coarsely toothed: fls. golden yellow, fragrant, 

 in 3-branched cymes; corolla tubular, about J^jin. long. 

 Japan. B.M. 8328. G.C. III. 46:244; same cut in III. 

 52:55. Useful in rock-garden work. The Ivs. are 

 mostly at the base of the plant, the fl.-sts. rising about 

 4 in. above them; fl. -clusters 3 1 in. across. 



gibbosa, Maxim. Differs from P. triloba in smaller 

 fls., rather larger not cordate Ivs. and st. not leafy: 

 about 9 in. high: Ivs. mostly radical and crowded, long- 

 petioled, suborbicular, the upper ones round-ovate to 

 ovate, acuminate, the base truncate or perhaps sub- 

 cordate, pinnately lobed, the lobes incised-serrate: fls. 

 yellow, the corolla distinctly gibbous at base; clusters 

 flat: Ivs. more or less blistered. Japan. 



P. intermedia, Roem. & Schult. (P. rupestris, Bunge, Fedia 

 rupestris, Hort.). 1-1 Ji ft.: Ivs. pinnatifid, the segms. lanceolate 

 with large terminal lobe: fls. yellow, fragrant, in May and June. 

 Siberia. B.M. 714 (as V. sibirica). P. sibirica, Juss. (Valeriana 

 sibirica. Linn.). 1 ft., most of the Ivs. radical, the cauline ones pin- 

 nate with entire segms., the radical long-spatulate, serrate, strong- 

 toothed or entire (even on same plant): fls. yellow, fragrant. 

 Siberia. B.M. 2325 (as V. ruthenica). L H B 



PAULLINIA (probably after Simon Paulli, 1608- 

 1680, professor of anatomy, surgery, and botany at 

 Copenhagen). Sapindacese. One species is a greenhouse 

 climber, which may also be grown as an upright fern- 

 like pot>-plant. 



Twining shrubs: Ivs. alternate, stipulate, compound, 

 1 3-ternate or pinnate, or decompound; petiole often 

 winged; Ifts. usually dentate, dotted or minutely lined: 

 racemes axillary, usually with 2 tendrils; fls. whitish or 

 pale, small; sepals 5, the 2 upper larger, connate; petals 

 4, but there is a fifth abortive one, two of the petals 

 smaller and bearing a scale below the apex; stamens 8; 

 ovary 3-celled, bearing a 3-parted style. Trop. Amer., 

 and sparingly in Afr.; species about 140. Distinguished 

 from allied genera, as Cardiospermum, by the septicidal 

 fr., which is often pear-shaped. P. thalictrifolia is a 

 handsome stove foliage plant, with much divided Ivs. 

 somewhat resembling a rue, maidenhair, or dayallia. 

 The fls. are inconspicuous, pinkish and borne in au- 

 tumn. Forty to fifty years ago, when the interest in 

 foliage plants was at its height, this plant was widely- 

 distributed. It used to be trained to a trellis for exhi- 

 bition or grown on the pillars and rafters of hothouses. 

 It is now a rare but choice plant for clothing the tops 

 of unsightly tubs in which palms are growing. It is 

 also excellent for large vases and stands the sun well. 

 The young Ivs. have a pretty bronze that unless they 

 are shaded too much. The plant is prop, by cuttings 

 of young shoots taken in early spring. If the tops are 

 pinched, the young plants will branch out and make 

 handsome specimens in 4- or 5- in. pots. 



thalictrifdlia, Juss. Lvs. 4-10 in. long, triangular in 

 outline, 3-ternately-pinnate; pinna? in 6-8 pairs; pin- 

 nules 4-8 pairs, 4-& lines long: fls. inconspicuous, pink-
