136 XV. POLYGALE^ (oliver). [Carpolobla^ 



acute, puberulous and ciliolate or glabrous ; the inner, about | in. long, con- 

 siderably exceeding the exterior, sometimes 2-3 times as long. Petals 2-3 

 times longer than the inner sepals. Fruit yellow or scarlet, usually 3-gonous 

 and 3-seeded or seeds fewer by abortion, edible.

 Var. parvifolia. Leaves smaller, 1-14 ^^'i ovate or ovate-lanceolate, obtuse, scarcely or 

 not at all acuminate. — Old Calabar, Mann ! Thomson ! 



2. C. lutea, Don, I. c. A small shrub, closely resembling C. alba. 

 Leaves as in C. alba. Flowers in axillary fascicles of 2 or 3-6. Sepals 

 ovate or ovate-lanceolate, subequal or inner rather larger, 2 lines or less. Pe- 

 tals white or pale yellow. 



Upper Guinea. Sierra Leone, Bon! Lagos, Abbeokuta, etc., Niger, Barter! Old 

 Calabar, Mann ! 



C. versicolor and C. dubia, Don, 1. c, belong to genera of Leguminosce, as shown by Mr. 

 Bentham (Fl. Nigrit. 224). 



With the above species in the herbarium of the British Museum is a third plant, collected 

 at Sierra Leone by Afzelius, which may be an uudescribed Garpolobia, or perhaps a new 

 generic type. I have not made an analysis of the flower. It has been written up as " Biadel- 

 phia pentandria, baccata." K is wholly glabrous or the racemes obsoletely puberulous. Leaves 

 coriaceous, elliptical, shortly acuminate or obtusely cuspidate, 2^-4 in. long, li-2 in. broad, 

 on petioles of I in. Racemes axillary, 2 or 3 together, rarely once-branched, 6-10-flowered, 

 1-1^ in. long. Sepals very unequal, obtuse, the inner longer. If a Carpolobia, the spe- 

 cific name Afzeliana may be assigned to it. 



Oeder XVI. FRANKENIACE^ (by Prof. Oliver). 



Flowers regular, hermaphrodite. Calyx garaosepalous, tubular, persistent, 

 4-6-toothed. Petals as many as calyx-teeth, free, clawed, with a laraelliform 

 appendage on the inner side of the claw. Stamens usually 6, hypogynous, 

 free or very shortly connate at base, rarely cohering above ; tilaments 

 flattened or filiform ; anthers 2-celled, didymous, dehiscing longitudinally. 

 Ovary 1-celled, with 3 (2-4) parietal multiovulate placentas ; style simple, 

 filiform ; stigmas 3 or as many as placentas. Capsule enclosed in the per- 

 sistent calyx, dehiscing in as many valves as placentas. Seeds albuminous, 

 with a straight axile embryo. — Much-branched Jierbs or small undershrubs, 

 affecting maritime or saline localities. Leaves small opposite exstipulate, 

 often fascicled. Flowers rose to purple, sessile and solitary in the numerous 

 forks or fascicled in leafy heads or cymes. 



An Order of one genus, like several other maritime genera of no marked affinity, widely 

 spread over the world in suitable localities.
