1. Tannodia Swynnertonii, Prain. 
In Engl. Pflanzenr, Euphorb.-Acalyph. Chrozophor. 110, this genus is recog- 
nised, but in the same work, p, 108, Holstia is treated as a genus apart from 
Tannodia and not as a section of Tannodia. 
1. Agrostistachys africana, J/iill. Arg. 
In Engl. Pflanzenr. Euphorb.-Acalyph. Chrozophor, 96, this plant is treated as 
the basis of a distinct genus, Pseudagrostistachys, Pax. Perhaps a sectional position 
isan adequate recognition of the status of this species.

& K. Hoffm. in Engl. Pflanzenr. Euphorb.-Acalyp. Chrozophor. 39. 
6. Caperonia serrata, Presi. Add: (. gallabatensis, Pax & 
K. Hoffm. in Engl. Pfanzenr. Euphorb.-Acalyph. Chrozophor. 39.

Deutsch, Zentr.-Afr, Exped. ii, 457. 
3. Hasskarlia minor, Prain in Kew Bulletin, 1912, 234. A 
glabrous herb 1-2 ft. high, sparingly branched. Leaves of the stem oppo- 
site, decussate, of the twigs opposite but anisophyllous below, alternate 
above, short-petioled, membranous, narrow-oblong, abruptly narrowly 
caudate-acuminate, base narrow-cuneate, margin below the middle entire, 
in the anterior half shortly sharply and closely toothed, 1-1} in. long, 3-3 
in. wide; petiole 1-3 in. long; stipules ovate, membranous, deciduous. 
Spikes towards the ends of the branches, leaf-opposed, dense-flowered, 
very short, 3-} in. long. Male: Calyx thinly membranous, 3-partite ; 
lobes valvate. Disk 0. Stamens 3, sessile on the receptacle ; anthers

Female flowers and fruit not seen. 
Upper Guinea. Sierra Leone: Limba; near Bendembu, Scott-Elliot, 5680 ! 
A very distinct species, with the habit of a Mercurialis or an Adenocline, but 
with male flowers that, except for the presence of a distinct though small rudi- 
mentary ovary, are not distinguishable from the male flowers of the two arborescent 
species. 
3. Erythrococca bongensis, Pax. Add: Mildbr. Wiss, Deutsch. 
Zentr.-Afr. Exped. ii. 458. H. mitis, Mildbr. 1.c. partly; not of Pax,
