PAULOWNIA

British Guiana. G.C. III. 23:307. Very showy. P. Kewensis, 

 Hort. " It is a cross raised 1 > y .Mr. Watson, the assistant cura- 

 tor, between the hardy Passifiora ccerulea and the Brazilian 

 P. Raddiana. The flowers are larger than those of P. Raddi- 

 ana, the petals and fringe longer, while the color is carmine 

 suffused with blue, which, though perhaps not so bright and 

 pleasing as it is in the parent, is a lovely color." P. Mlersii, 

 Mast. Stems slender and wiry: Ivs. lance-ovate and entire, 

 claret-colored beneath: fl.2in. across, white, shaded with pink, 

 the corona half the length of the petals, white, barred with 

 purple. Brazil. G.C. III. 4:353. P. triloba, Ruiz & Pav. Lvs. 

 large, cordate-ovate, 3-lobed or entire: fl. 3 in. across, with vio- 

 let reflexed sepals and petals, and a long cup-like corona, with 

 filaments banded white and purple. Peru. I.H. 36:83. P. 

 Wcfx'riana, Andre. Glandular-hairy: Ivs. large, 3-lobed, the 

 margin usually toothed: fl. solitary, 2 in. across, white, the 

 corona banded with white: fr. setose, purple. Argentina.

PASTINACA (name from the Latin pastus, food). 

 Cinhelliferce. About a half dozen species of tall herbs 

 native to Europe and Asia, but by Bentham & Hooker 

 united with the genus Peucedanum. It is distinguished 

 from Heracleum and Peucedanum by technical charac- 

 ters of the fruit. Pastinaca is known to horticulturists 

 in the Parsnip (which see), P. sativa, Linn. It is a na- 

 tive of Europe, but is now grown in nearly all cool-tem- 

 perate countries for its large edible root. In deep moist 

 soil and a cool climate, the edible roots become 18-20 

 inches long and four inches or more in diameter at the 

 crown. It was cultivated before the Christian era. It 

 has run wild from gardens, often becoming a bad weed 

 in neglected fields and on roadsides. P. sativa is a robust 

 plant, sending up a grooved stem (which becomes hollow) 

 3-5 ft. : Ivs. odd-pinnate, with 3-4 pairs of sessile ovate- 

 oblong sharp-toothed and notched leaflets, the terminal 

 leaflet 3-lobed : fruit ("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.

PATIENCE. Patience Dock or Herb Patience is 



J^itmcjr 1'atientia. 



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

 in Siberia). Valerianacew. About 10 species of yellow- 

 or white-fld., valerian-like, hardy herbaceous peren- 

 nials from extra-tropical Asia. They grow a foot or so 

 high, bloom in early summer and may have about 20 

 small fls. in clusters 2 in. across. Two species are of- 

 fered by dealers in Japanese plants. 



Patrinia is distinguished from the other 8 genera in 

 the Valerian family by 4 stamens and mostly yellow fls. 

 Valeriana has 3 stamens. Nardostachys, with 4 stamens, 

 has purple fls. Patrinias are glabrous or loosely villous : 

 Ivs. once or twice pinnatifid or -sect, the radical ones 

 rarely entire: cymes corymbose-panicled : bracts nar- 

 row, free, but sometimes appendaged with a large, 2- 

 nerved and netted-veined bracteole which is appressed 

 to the f r. : corolla- tube very short; lobes 5, spreading: 

 sterile locules of the fruit nearly as large or larger than 

 the fertile ones. 



A. Stem glabrous. 



scabiosaefdlia, Fisch. Radical Ivs. ovate or oblong, in- 

 cised-serrate and lyrate : cauline Ivs. pinnatifid, the 

 lobes lunceolate-linear, acute, terminal one longest: fls. 

 yellow: corymb loosely subpaniculate : fr. 3-cornered. 

 Dahuria. L.B.C. 14:1340. 



AA. Stem villous. 



villdsa, Juss. Radical Ivs. villous, petiolate, auricled : 

 cauline Ivs. sessile, dentate: corymb panicled. Japan. 

 The plant offered by the Yokohama Nursery Co. is 

 said to have white fls. 



PAULLlNIA (probably after Simon Paulli, 1608-1680, 

 professor of anatomy, surgery and botany at Copenha- 

 gen). SapindacecK. P. thalictrifolia is a handsome stove 

 foliage plant, with much divided Ivs. somewhat resem- 

 bling a rue, maidenhair, or a davallia. The fls. are in- 

 conspicuous, pinkish and borne in autumn. In the early 

 seventies, when the interest in foliage plants was at its 

 height, this plant was widely distributed. It used to be 



trained to a trellis for exhibition 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 \\liich 

 palms are growing. G. W. Oliver says it is also excel- 

 lent for large vases and stands the sun well. The young 

 leaves have a pretty bronze tint 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. For potting soil an Eng- 

 lish gardener recommends compost of two-thirds fibrous 

 peat to one-third of loam, with a liberal sprinkling of 

 silver sand. 



Paullinia is a genus of about 80 species, mostly tropi- 

 cal American. Twining shrubs : Ivs. alternate, stipulate, 

 compound, 1-3-ternate or pinnate, or decompound; peti- 

 ole often winged ; Ifts. usually dentate, dotted or mi- 

 nutely lined: racemes axillary, usually with 2 tendrils: 

 sepals 5, the 2 upper larger, connate: petals 4, but there 

 is a fifth abortive one: stamens 8: ovary 3-celled. Dis- 

 tinguished from allied genera, as Cardiospermum, by the 

 septicidal fr., which is often pear-shaped. 



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

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

 nules 4-8 pairs, 4-8 lines long. Brazil. B.M. 5879. Gn. 

 51, p. 160. F. 1873, p. 124. Var. argSntea, Hort., has 

 foliage suffused silvery gray. 



1653. 



Passifiora ccerulea, the commonest cultivated 

 Passion-flower (X%). 



PAULO WNIA (after Anna Paulowna, princess of the 

 Netherlands). Scrophulariacece . Ornamental decidu- 

 ous trees, in habit and foliage similar to Catalpa, with 

 ample, long-petioled, opposite Ivs., and pale violet large 

 fls. resembling those of the foxglove in shape, in ter- 

 minal panicles opening before the Ivs. The species 

 in cultivation is fairly hardy in sheltered positions as 

 far north as Mass., but the fl.-buds are usually killed in 

 winter, and it does not flower regularly north of New 

 York city. As an ornamental foliage plant it may be 

 grown as far north as Montreal, where it is killed to the 

 ground every winter, but throws up from the root vigor 

 ous shoots attaining 10-14 ft. .with Ivs. over 1 ft. and occa- 

 sionally even 2 ft. long. If used as a foliage plant and
