18 III. ANONACE^ (olivee). \_Jnona. 



slightly reflexed from the thickened or obtusely-keeled centre ; base narrower, 

 concave, erect or slightly spreading. Stamens indefinite ; anthers linear- 

 oblong, extrorse, subsessile ; connective produced into a short very obtuse 

 tip, scarcely dilated. Torus convex. Carpels free, indefinite, closely packed ; 

 ovary pilose ; stigma shorter than the ovary, linear-oblong, sulcate on the 

 inner face, pilose ; ovules solitary, erect. Fruit not seen. 



A tree, with rather large membranous leaves, and solitary, shortly pedancled extra- axillary 

 flowers. 



I have based this new genus upon the single species described below, which differs from all 

 known Anonacece in the total suppression of the outer petals. Excepting in this particular 

 (and the free ovaries) the flowers resemble those of an Annna, in which genus, however, the 

 tendency is to suppression of the inner series of petals. Technically it is allied to the Pha- 

 anthece. 



1. E. chlorantha^ OUv. I.e. Ultimate branchlets slender, pubescent. 

 Leaves membranous, obovate- or oblanceolate-oblong, shortly acuminate, 

 cuneate or scarcely rounded at the base, glabrous excepting the puberulous 

 midrib above and petioles, 5-10 in. long, 2-3| in. broad ; petiole 1|~3 lines. 

 Flowers solitary, extra-axillary, on peduncles of about half an inch, Avith 1 or 2 

 lanceolate or ovate-lanceolate sepal-like bracts above the middle, appressed- 

 pilose externally. Sepals lanceolate, subacute, 6-8 lines long, strigose-pilose 

 outside, dark and glabrate within, spreading or refiexed. Inner petals 1-H 

 in. long, 6-8 lines broad, rather obtuse, with closely appressed minute hairs 

 externally. 



Upper Guinea. Old Calabar, Thomson ! 



3. PIPTOSTIGMA, Ollv. in Journ. Linn. Soc. viii. 158. 



Flowers hermaphrodite. Sepals 3, ovate or lanceolate, acute, free. Petals 

 6, free, in two series, valvate in aestivation ; outer petals sepaloid, but slightly 

 exceeding the sepals ; inner petals much longer than the outer, rather thin, 

 plane or the margins refiexed ; the base concave, surrounding the genitalia. 

 Stamens indefinite, closely imbricate upon a hemispherical torus ; anthers 

 sessile, cuneate-oblong, extrorse, the connective truncate, transversely rhom- 

 boidal. Carpels 4-6, united at the apex in a sessile, depressed-globose, ob- 

 scurely-lbbed, pilose, deciduous stigma; ovules 6-10, in 1 or 2 series upon 

 the ventral suture. Fruit not seen (said to consist in one species of united 

 carpels). 



Trees, with subsessile leaves, with numerous, secondary nerves and obscure transversely 

 parallel venation, and simple or panicled cyinose racemes, from v/^ood of a previous year. 



The two following species are all that are known of this genus, which is conliuedto West 

 Tropical Africa. 



Leaves sparsely pilose beneath, abruptly cuspidate. Racemes elongate, 

 simple or forked. Bracts linear-lanceolate. Outer petals linear- 

 lanceolate or lanceolate 1. P.pilosum. 



Leaves glabrous or glabrate, shortly acuminate. Panicles dichotoraous. 



Bracts ovate, acute. Outer i)etals ovate or ovate-lanceolate . . . 2. P. glabrescens. 



1. P. pilosuxn, Ollv. I. c. Extremities softly tomentose with ferrugi- 

 nous hairs. Leaves membranous, subsessile, obovate-oblong, shortly apicu- 

 late, rounded at the base, glabrous above, more or less pilose beneath espe-
