6 04 Prain.—A Review of the Genera 
1. Euerythrococca . 1 Stigmas plumosely laciniate or at least incised 
lobulate. 
2. Athroandra, Hook. f. Stigmas entire. 
II. CLAOXYLON, A. Juss. Buds not perulate. Racemes uniformly 
floriferous. Capsule subglobose, coriaceous ; cocci dehiscing loculicidally : 
subdivided into :— 
1. Euclaoxylon, Muell. arg. 2 Male flowers with only interstaminal 
glands. 
2. Discoclaoxylon, Muell. arg. Male flowers with only an extra- 
staminal urceolum. 
III. Micrococca, Benth. ampl. Buds not perulate. Racemes inter¬ 
rupted. Capsule deeply 3-coccous, thinly crustaceous ; cocci dehiscing both 
septicidally and loculicidally. 
The necessity for some modification of view as regards the limitation 
of Micrococca , Benth., was impressed on Sir J. D. Hooker when engaged 
in the task of dealing with the Indian species of the genus Claoxylon. The 
necessity for a corresponding modification of view as regards the limits of 
Erythrococca, Benth., has been similarly impressed upon the writer while 
occupied in the preparation, at the request of Sir W. T. Thiselton-Dyer, of 
an account of the African species from time to time referred to Claoxylon , for 
the ‘Flora of Tropical Africa’. The extension of the limits of Micrococca, 
which Hooker has shown to be essential, and the corresponding extension 
of Eiythrococca, for which we are similarly indebted to Pax, to which effect 
is here given, departs from the treatment proposed by these authors only 
in that Micrococca , looked upon by Hooker as a section of Claoxylon, is 
here considered a distinct genus, while the genus Erythrococca is made to 
include, besides the section Adenoclaoxylon , also the section Athroandra . 
The action here taken involves, therefore, some modification of the 
estimate hitherto formed with regard to the dimensions of the genus 
Claoxylon. The restriction of this latter genus is, however, to a certain 
extent compensated for by the fact that these transfers simplify materially 
our conception of its geographical distribution. Micrococca , which up to 
1887 was believed to be monotypic, is now known to include eight distinct 
species and one recognizable variety, and to extend from South-East and 
East Africa and the Comoro Islands to South-West Peninsular India and 
Ceylon, with one of the species, which is a tropical field-weed, further 
spread throughout the greater part of Tropical Africa, Southern Arabia, 
the greater part of India, Western Indo-China, and the Malay Peninsula. 
Erythrococca , which up to 1894 was also believed to be monotypic, is now 
known to include over forty recognizable forms, all of them confined to the
