He groups the species into : — 



Series I, Renantherce. — Stamens all perfect or very rarely (especially E. vvrgata). (This is really 

 E. Sieberiana. — J.H.M.). Some of the outer ones with abortive anthers; anthers reniform or broad 

 and flat-, the cells divergent or at length divaricate, contiguous and usually confluent at the apex. 



Series II, Heteroslemones. — Outer stamens (usually longer than the others) anantherous or with 

 small abortive anthers; anthers of the perfect ones small, globose or truncate; the cells contiguous, 

 opening in pores or oblong slits, sometimes at length confluent. 



Series III, PorantJierce. — Stamens all perfect, except rarely in E. bicolor and perhaps in E. poly- 

 anthemos; anthers small and globular or broader than long, the cells distinct, opening in terminal or more 

 or less lateral circular pores, sometimes extending at length into oblong slits. 



Series IV, Micrantherw. — Anthers very small and globular or broader than long, almost as in the 

 Porantherse, but opening in more oblong or longitudinal slits, almost as in the Normales, the cells more 

 distinct than in the Porantheroe, less so than in the Normales. 



Series V, Normales. — Stamens all perfect; anthers oblong-ovate or nearly globose, the cells 

 perfectly distinct, parallel, and opening longitudinally, either contiguous with the connective -gland behind 

 them or back to back with the connective between them. 



(It will be seen that, in the above definitions, the species are grouped according 

 to the shape and mode of dehiscence of the anthers.) 



Series I. Renantherse, 



E. Risdoni. 

 E. dives. 

 E. stellulata. 

 E. coriacea. 



E. viraata. (This is really E. Sieberiana, 

 or virgata in addition to Sieberiana) . 

 E. obtusijlora. 

 E. obliqua. 

 E. bupresiium. 

 E. amygdalina. 



E. coccifera. 



E. piperita. 



E. capitellata. 



E. macrorrhij neha. 



E. santalifolia. 



E. pilularis var. acmenioides (E. 



acmenioides). 

 E. pilularis. 

 E. marginata. 



(This is a very natural group; I will make some suggestions later on.) 



Series II. Heterostemones. 



E. leucoxylon. E. bicolor. 



E. melliodora. E. paniculata. 



E. gracilis. E. haemastoma. 



E. virgaia. E. microcorys. 



(In this group we have virgata, included by Bentham himself also in the 

 Renantherge, and also hcemastoma and microcorys, placed by Mueller in the 

 Renanther*. E. leucoxylon, melliodora, and paniculata have truncate anthers, see 

 p. 530.) 



Series III, Poranllierce. — Stamens all perfect (except rarely in E. bicolor and perhaps in E. 

 polyanlhemos) ; anthers small and globular or broader than long, the cells distinct, opening in small circular 

 pores, sometimes extending at length into oblong slits. 



The species are all Eastern or Tropical, including most of the " Box-trees," E. uncinate alone 

 extending also into West Australia. The leaves when narrow have always an oblique irregular venation. 

 The operculum is short, and the capsule sunk in the fruit.
