E. gracilis. E. hcemasloma, E. paniculala, E. pohjanthemos, E. tiieberiana. 



It will be seen that Mueller's list includes the following species not in BentJiam's? : 



E. acmenioides. E. stricta. 



E. doraloxylon. E. Todtiana. 



Of these, the first and the last were not in the latter's list of species. 



Connective (Gland). 



" When the two cells are not closely contiguous; the portion of the anther that unites them is called 

 the Connective . . . . " (B. Fl. I. xv.). " . . . . the connective often thickened into a 



small gland either separating the cells or behind them when they arc contiguous." (Ill, 185). 

 " Normalea .... cells perfectly distinct, parallel (either contiguous with the connective gland 

 behind them, or back to back, with the connective between them) . . . . " (p. 193). 



I cannot find that Bentham described the gland of any particular species. In 

 Sachs' " Botany " (English translation), we have — 



"The anther therefore usually consists of two longitudinal halves, united and at the same time 

 separated by a part of the filament termed the Connective. The two pollen-sacs of each half of the anther 

 an- contiguous throughout their length, and frequently both halves of the anther are in close apposition. 

 The Beparate pollen-sacs then appear as compartments of the anther, which is in this case quadrilocular, 

 in contrast to those anthers (of rare occurrence) in which each half contains only a single pollen-sac, and 

 which are therefore bilocular." (Sachs. 427.) It is "convenient to term them (the stamens) Stamina] 

 leaves; the filament, together with the connective, being considered as the leaf of which the two anther- 

 adages." (p. 173). 



Mueller (" Eucalyptographia ") has not much to say about the gland; following 

 are all the passages I can trace. His references are scattered, and I do not think he 

 considered it as an important character. In addition, he often figures the gland 

 (sometimes diagrammatically). • 



". . . . Connective of anthers usually raised at the summit or dorsally towards the top into a 

 callous gland . . . ." (End of Part x, description of the genus). 



E. dioersicohr. Longil udinal slits, enlarged by a conspicuous terminal gland. 



E. gomphoccphala. Doi al gland ol anther conspicuous. 



A', iiirrwssata. Connective conspicuously glandular turgid at the back. 



E. Jongifolia. ' onnective ol the anthers conspicuously callous-glandular. 



E. mactilata. Connective of the anthers broader than the very narrow glandular portion (
