500 NOTES ON HYBRIDISATION IN THE GENUS 'EUCALYPTUS, 



statement that this form only occurs in plantations "of E. 

 viminalis growing with E. globulus " is a sufficient explanation. 



The seedlings of E. Bduerleni F.v.M. {E. viminalis Labill. var. 

 Bduerleni Deane & Maiden) are identical with those of Mr. 

 Rodway's variety. The fruits also have much in common, but 

 those of Mr. Rodway are usually more domed. The rim of the 

 junction of the calyx and operculum is very prominent in var. 

 Bduerleni; I have not ripe buds. The ripe buds of var. macro- 

 carpa are rounded and glaucous. 



The two forms (so called) of E. vijiiinalis, viz., var. macrocarpa 

 and var. Bduerleni, are undoubtedly closely related. I think 

 var. macrocarpa is a hybrid of E. viminalis x globulus. Whether 

 var. Bduerleni is also a hybrid I cannot say, but I incline to 

 think it is, the parents being possibly E. viminalis and E. 

 Maideni F.v.M. 



E. KiTSONi Luehmann, and E. neglecta Maiden. 



In describing* these two species, I have expressed the opinion 

 that they are both hybrids of E. Gunnii Hook. f. 



E. gomphocornuta Trabut. 



See my remarks in these Proceedings (1903, p.900). I have 

 since received excellent specimens from Dr. Trabut. This plant is 

 an interesting hybrid, of which E. gomphocephala is undoubtedly 

 a parent. As to the other parent, I think it is less likely to be 

 E. cornuta Labill., than E. occidentalis Endl. The characteristic 

 bell-shape of the fruit of the latter species is well brought out in 

 the specimens before me. Dr. Trabut's illustration (in Rev. 

 Hort.) was made from fresh specimens; dried specimens show 

 construction which accentuates the bell-shape. 



E. ALGERiKNSis Trabut, Rev. Hort. de I'Algerie, Juin, 1904,p.l46. 



This is a species that Dr. Trabut looks upon as E. rostrata 

 Schlecht. X rudis Endl., but he does not formally describe it.
