in length ; leaflets of each pinna 6-11, ovate-elliptical lanceolate or 

 elliptic- oblong-, more or less oblique, obtusely usually shortly acumi- 

 nate often submarginate, rounded or broadly cuneate at base, midrib 

 and venation rather prominent, glabrous, or midrib pubescent beneath ; 

 1J-4J in. long ; petiolule \-\ in. Flowers crowded, \ in. long, pubes- 

 cent ; the petals pilose-tomentose towards the margin. Stigma at first 

 subsessile concealed by the long tomentum of the ovary, at length 

 borne upon a distinct, nearly glabrous style. Follicular legumes 2J- 

 5 in. long, 1-1 J in. broad, usually 5-8-seeded, apex obtusely rounded 

 or broadly apiculate, base at length very oblique, obtuse ; gynophore

The bark is powerfully poisonous, and is administered by native tribes in widely re- 

 mote regions as an ordeal. 



Dr. Bolle, who bad only fruiting specimens to describe, states, 1. c, that the legumes 

 are 6 in. long by about 1 in. broad. I have not seen fruits so narrow in proportion to 

 their length from Western Africa, but Mr. Baker, who has compared Dr. Bolle's plant 

 with Barter's, has noted them as specifically identical. 



Guillemin and Perrottet, 1. c, state that the seeds are invested with pulp. Of this 

 but little or no trace remains in the dry fruit. I have not seen specimens of the 

 Erythrophloeum or Cassa of the Congo referred to by B. Brown in " Botany of Congo," 

 430. 



Suborder III. Mimose^. (By Prof. Oliver.) 



Flowers regular, usually 5-merous (4-6-merous). Sepals usually 

 connate in a 5-toothed or -lobed calyx. Petals as many as sepals, free 

 or connate, hypogynous or subperigynous, valvate in aestivation. Sta- 

 mens as many or twice as many as petals or indefinite, free or mon- 

 adelphous ; anthers minute, dehiscing longitudinally. Seeds elliptical 

 or roundish compressed. "Albumen or sparing, ttadicle short 

 straight." — Shrubs or trees, rarely herbaceous. Leaves bipinnate. 

 Flowers small, sessile or shortly pedicellate, capitate or spicate. 



Of the 28 genera of this Suborder, 17 are represented in Tropical Africa. Not one is 

 peculiar to this Flora. 



Tribe 1. Parkiese. — Calyx-teeth imbricate. Stamens 5 or 10 ; anthers with a 

 deciduous apical gland. 



Stamens 5, staminodia 10-15. Flowers spicate 1. Pentaclethba. 



Stamens 10, staminodia 0. Flowers capitate 2. Parkia. 



Tribe 2. Adenantherese. — Calyx valvate. Stamens 10 (rarely 5); anthers with 

 a deciduous apical gland. 



Flowers spicate. Sutures of legume persisting after separation of 



the 1-seeded articles 3. Entada. 



Flowers spicate. Legume 2-valved, flat, coriaceous, continuous . 4. Piptadenia. 



Flowers racemose. Legume linear, 2-valved, valves coriaceous, 

 entire (turgid over the brightly coloured seeds) 5. Adenanthera.
