4, ANTHEROTOMA, Hook. f.; Benth. et Hook. f. 
Gen. Plant. i. 745. 
Calyx broadly campanulate, setose ; lobes 4-5, triangular, persistent, 
alternating with bristles or stellately et appendages. Petals 4-5, 
obovate, tip setose. Stamens 8-10, equal; anthers similar, oblong, 
terete, truncate, pore large; connective simple or produced and 
2-tubercled at the base. Ovary adherent halfway, 4—5-celled, tip with 
a crown of bristles; style filiform; stigma simple. Capsule mem- 
branous, 4—5-valved. Seeds cochleate.——Small, erect, slender, sub- 
simple, setose annuals. Leaves subsessile, ovate-oblong, acute, quite 
entire or obscurely serrate. Flowers small, 8-nate or subcapitate, 
involucrate. 2 
A small genus, confined to Tropical Africa and Madagascar.

1. A. Naudini, Zook. f. Stem 3-6 in., 4-angled, rarely branched. 
Leaves in verv few pairs, 4—} in., variable in breadth. Flowers sur- 
rounded by 4 floral leaves, shortly pedicelled, }in. in diameter, 4- 
merous. Anthers with the connective produced below, 9-tubercled 
at the base.—Osbechia antherotoma, Naud. in Ann. Sc. Nat. sér. 3,

Also found in Madagascar and Mayotte Island. 
2. A. Afzelii, Hook. f. Stem 6-8 in., 2-3-chotomously branched ; 
nodes long-ciliate. Leaves 4—1 in. by {4 in., shortly petioled, linear 
or elliptic-oblong or ovate, sparsely setose on both surfaces, obscurely 
serrate. Flowers crowded, 5-merous, subcapitate, }in. in diameter. 
Anthers seated on the very slender subulate tip of the filament; 
connective obsolete below.

In the form of the connective and 5-merous flowers, this differs remarkably from A, 
Naudini, but the habit and all other characters are so similar that I cannot think it 
should constitute a separate genus. From Guyonia, with which it agrees better in the 
anthers, it differs in the far more important characters of calyx and stigma. 
5. DINOPHORA, Benth.; Benth. et Hook. f. Gen. Plant. i. 749- 
Calyx glabrous, between turbinate and urceolate ; limb membranous, 
sinuate-toothed. Petals 5, broadly ovate, subacute. Stamens 10, equal, 
anthers similar, linear-subulate, pore single; connective shortly pro 
duced at the base, dilated and notched in front. Ovary adhering by 
5 ribs to the calyx-tube, pacar style filiform, narrowed at the base 
stigma truncate. Capsule membranous, bursting irregularly or sub- 
valvate. Seeds minute, cochleate.—A glabrous s rub, branches herba- 
ceous, 4-angled. Leaves petioled, oblong-ovate or lanceolate, bas?
