Remarkable in the Order in its peculiar venation, which resembles that of the genus 

 Calophyllum.

Sepals 5. Petals 5, usually villous within. Stamens 5-adelphous; pha- 

 langes opposite to the petals, oligandrous ; squamae 5, alternating with the 

 phalanges. Ovary 5-celled ; styles distinct ; stigmas clavate-capitate ; ovules 

 solitary (or geminate), ascending. Pruit baccate, indehiscent. Seeds erect, 

 unappendaged ; testa (at least sometimes) with conspicuous immersed 

 glands ; embryo straight ; cotyledons convolute or plano-convex, radicle 

 short. — Shrubs or trees. Leaves opposite, sometimes with interpetiolar con- 

 necting lines. Plowers in terminal or lateral cymes. 



A genus of 10 or 12 species confined to Tropical Africa and Madagascar. See remaiks 

 under Vismia. I have not identified any of the following with insular species : 



Densely tomentose. Leaves alternate or opposite, elliptical or ob- 

 long-elliptical 1. -P- senegalensc. 



Extremities tomentose or glabrous. Leaves rather coriaceous, broadly 

 elliptical to oblong, obtuse or broadly acute, reticulate and glabrous 

 or rusty-tomentose beneath. Petiole 1-2 lines or 2. P . febrifngum. 



Glabrous. Leaves submembranous, elliptical, acute or obtusely acu- 

 minate. Flowers in terminal cymes. Petiole 2-3 lines . • • 3. P. tenutfohum. 



Glabrous. Leaves coriaceous, obovate-elliptical, lower alternate. . 



" Panicles axillary or lateral." Petiole 4-6 lines 4. P. altermfolwn. 



1. P. senegalense, Spach in Ann. Sc. Nat. Ser. 2. v. 164. Shrub; 

 the branches and young leaves clothed with a pale rusty-brown tomentum, 

 deciduous on the old wood and partially on the upper surface of the leaves, 

 which are opposite or alternate, elliptical or oblong-elliptical, subacute or 

 obtusely apiculate, narrowed or rounded at the base, but not cordate, 2- i 

 in. long, 1-1 \ in. broad; petioles 2-3 lines. Plowers densely tomentose, 

 in axillary and terminal umbellate panicles shorter than the leaves or collect 

 in terminal corymbose panicles a little exceeding the uppermost leaves. Mj 

 mentose pedicels equalling or twice as long as the calyx. Stamens 5-8 l 

 each phalange. Ovules solitary, ascending.— PI. Seneg. t. 23 (exclusive oj 

 the dissections). (Vismia guineensis, Chois. Monog. Hyper. 36 ?)

2. P. febrifugum, Spach in Ann. Sc. Nat. Ser. 2. v. 163. A shrub or 

 small tree. Extremities rusty pubescent-tomentose at first or rarely gla- 

 brous. Leaves usually opposite, rarely ternate, rather coriaceous, narr0 ^ 

 or broadly elliptical, broadly pointed or obtuse, rarely broader above t 

 middle, more or less rounded, subcordate, sometimes slightly narrowed 

 the base, soon glabrous and shining above, thinly pubescent or midrib on 

 pubescent and finely reticulated with paler areolae beneath, 1-4 in. long, T
