PAVETTA 



PAVOXIA 



2489 



cylindrical or funnel-shaped commonly slender tube, 

 the throat mostly bearded or pubescent, the limb pre- 

 vailingly 5-parted (rarely 4-parted) into oval or oblong 

 contorted lobes; stamens 4 or sometimes 5, affixed at 

 the mouth of the corolla: style conspicuously exserted, 

 the stigma entire or 2-toothed: fr. a pea-shaped some- 

 what fleshy 2-pyrenous berry. One hundred or more 

 spjecies in the tropical and subtropical parts of the Old 

 World, to the Philippines, with recent numerous exten- 

 sions in Trop. Afr. Only a few of the species are in 

 cult., and these are known as warmhouse or warm 

 temperate plants. 



The pavettas are fine tropical stove evergreens and 

 should be more grown. P. borbonica can be propagated 

 from half-ripened wood, leaving an eye and a leaf 

 attached. These cuttings may be put into 2-inch pots, 

 using a mixture of fibry peat and sand in equal parts. 

 These pots may be plunged in a propagating-bed that 

 has a bottom heat of 80 to 85. Coyer with glass so as 

 to keep a humid atmosphere. It will take some little 

 time before they make roots. Keep shaded and moist 

 until this takes place. When roots are seen in the pots, 

 gradually give more air until they are exposed to the 

 full atmosphere of the house. They may also be propa- 

 gated by being cut down well to make them throw many 

 young soft cuttings that can be rooted with a brisk 

 bottom heat. P. caffra will root freely from cuttings 

 of young growth, placed where they have plenty of 

 bottom heat. The pots may be plunged in the propa- 

 gating-bed up to the rims. Keep shaded, moist and close 

 for about a month. The best season for the increase of 

 this class of plants is January to March. The general 

 culture for P. borbonica is to keep increasing the 

 shifts until they are in 7- or 8-inch pots, using a compost 

 of fibrous loam three parts, fibrous peat two parts, and 

 well-decayed manure one part. Give each pot good 

 drainage. In the spring and summer provide a night 

 temperature of 70, with 10 to 15 more by day with 

 sun. Supply water when they show dryness of the 

 ball. Keep well syringed. They will need some shade in 

 the summer to keep the foliage perfect. In midwinter 

 the temperature for night may be lowered to about 60. 

 P. caffra. which is a free bloomer, will need different 

 culture. It should be kept growing by shifting as the 

 plants may require, until they are in 6- or 7-inch pots or 

 larger. For summer culture, treat the same as for P. 

 borbonica only they will not need so much heat, 60 to 

 65 being sufficient, with 10 more during the day. They 

 will stand pinching to make them bushy. The tempera- 

 ture in the winter should be from 50 to 55. The fol- 

 lowing spring give more pot room and grow on the same 

 as before. Give liquid manure at intervals in the grow- 

 ing season and by autumn they will show bloom. By 

 giving root room, with liquid feeding and by heading 

 in annually, they will bloom for years. Scale and mealy- 

 bug thrive on pavettas, and the plants must be care- 

 fully watched. (J. J. M. Farrell.) 



A. Foliage variegated. 



borbonica, Hort. A foliage plant with unknown fls., 

 referred arbitrarily to this genus: Ivs. about 9 in. long, 

 oblong-acuminate, rounded at the base, with a salmon- 

 red midrib, mottled with light green on a dark green 

 ground. Bourbon Isl. Lowe 5. 



AA. Foliage not variegated. 

 B. Calyx-teeth setaceous and much longer than the tube. 



caffra, Linn. f. (libra caffra, Poir. P. corymbbsa, 

 Houtt.). Shrub with whitish branches, to 6 ft., the 

 branches terete and glabrous: Ivs. almost sessile, obo- 

 vate. glabrous (or in var. piibescens, Sond., branches 

 and Ivs. pubescent), the margins slightly recurved, to 2 

 in. long; stipules broad and cuspidate: fls. white, the 

 tube J^in. long, in densely fld. corymbs; calyx-teeth 

 Kin. long: fr. black and shining. S. Afr. B.M. 3580. 

 Gn. 60. p. 414. J.F. 3:294. 



natalensis, Sond. Shrub, glabrous, with young 

 branches compressed: Ivs. petioled, lance-acuminate, 

 attenuate at base, shining, 3-4 in. long; stipules cus- 

 pidate-acuminate: fls. white, in a loose corymb. Natal. 



BB. Calyx-teeth short-triangular, shorter than the tube, or 



sometimes practically wanting. 



indica, Linn. A variable small tree or bush, common 

 in India, extending to China and Austral.: glabrous, 

 pubescent or tomentose : Ivs. from elliptic to obovate or 

 oblaneeolate or even orbicular, at the apex from obtuse 

 to caudate: fls. slender-stalked, white, fragrant, the 

 corolla-tube %~%in. long: infl. corymb-like, terminal 

 and sessile. B.R. 198, which is var. polydntha, Hook, 

 f., with densely crowded pubescent fls. The species 

 has many synonyms. L. H. B. 



PA VIA: jEsculus. 



PAVONIA (J. Pavqn, joint author of Ruiz and 

 Pavon's "Flora Peruviana et Chilensis"; died 1844). 

 Malvacex. Herbs or shrubs, one or two of which are 

 sometimes grown under glass as pot subjects, for the 

 showy bloom. 



Tropical plants, tomentose, hispid or glabrescent: 

 Ivs. often angled or lobed: fls. of various colors, pedun- 

 cled or crowded at the tips of the branches: bractlets 

 5 to many, distinct or more or less connate and resem- 

 bling a calyx, usually not colored: calyx 5-cut or 5- 

 toothed; petals spreading or con volute-conni vent; 

 stamina! column truncate below the apex or 5-dentate; 

 ovary 5-loculed, 1-ovuled: ripe carpels surrounding the 

 axis and separating from it, rounded or truncate at top, 

 sometimes winged, indehiscent or imperfectly dehis- 

 cent, prickly or awned. Species about 100, Cent. Amer. 

 to Argentina; also in Trop. Afr. and Asia, to Austral, 

 and the Pacific. The genus is more or less confused 

 with Goethea, but that genus, as usually denned, differs 

 in its larger and more showy fl.-bracts and in the 

 smooth carpels. The plants in cult, derive much of 

 their interest from the showy bracts, although Pavqnia 

 is usually characterized as having bracts less conspicu- 

 ous than those of Goethea. 



multifldra, St. Hil. (P. Wloti, Morr. Goethea multi- 

 flora, Nichols.). Robust, with a stout usually simple 

 st.: Ivs. alternate, 6-10 in. long, narrowly oblong- or 

 obovate-lanceolate, long-acuminate, serrate or dentic- 

 ulate: fls. in a short terminal corymb; bractlets beneath 

 the fl. numerous, narrow-linear, whorled, red-hairy, 

 curving, in length about equaling the rolled-together 

 purple corolla (which is 1-1 K m - long); calyx-segms. 

 much shorter than the bractlets; column of stamens 2J^ 

 in. long and prominently exserted. Brazil. B.M. 6398. 

 F.M. 1877:276. What is known as P. intermedia by 

 gardeners is apparently not P. intermedia, St. Hil.; it is 

 said to be derived from P. multiflora. There are forms of 

 P. intermedia, Hort., known as var. rosea, var. flori- 

 bunda, and var. kermesina. This group of plants is 

 readily grown from cuttings taken in spring or early 

 summer, and good blooming plants in 5-in. pots may 

 be had by winter. They grow naturally to about one 

 st., and should not be pinched back. They make 

 attractive pot subjects with the terminal clusters of fls. 

 marked by the long-protruding stamina! column with 

 hanging bluish anthers, the narrow rolled corolla and 

 the slender conspicuous bracts. 



spinifei, Willd. Shrub, to 20 ft., from S. Amer., the 

 st. slender, branches few and virgate: Ivs. ovate, cor- 

 date, crenate sometimes angled, pubescent on both 

 surfaces: fls. large, yellow, not fragrant, the corolla 

 open ; petals obovate ; calyx-lobes lanceolate : bracteoles 

 5 or more, linear, hairy on margin : caps, with 3 spines. 

 B.R. 339. 



prsemorsa, Cav. Shrub with rodlike branches, 

 from S. Afr. : Ivs. broad-ovate or fan-shaped, truncate, 

 obtusely dentate, canescent beneath, with petiole and
