E. cneorifolia, D.C. 



11a. Twig bearing buds; 1 1 6, bud, enlarged ; lie, fruits, being reproductions of portions of the original 

 drawings of Eucalyptus cneorifolia, DC. in " M^moire sur la Faniille des Myrtac^es " par Aug. 

 Pyr. Ue Candolle (1842). PI. 9. 



The fruits are probably those of E. cneorifolia, and the mix-up is referred to at p 280, 

 Vol 1 of this work, as well as in the present Part. \ 



12. On the original of this specimen in the De Candollean (Prodronius) herbarium are the following 



notes : — 



(a) " 34 (see DC. Prod, iii- 220. J.H.M.) Sub E. cneorifolia, D.C, species duse manifestse 



adsunt in Hb. Prodromi, a DO. confusse (fee." 

 (6) " Eucalyptus Nile Hollande, ile Decres, Musee de Paris, 1821." 

 (c) " (1) Species foliis /tnearte'-lanceolatis habitu virgato, ifcc." 

 This is the plant we know as E. cneorifolia, D.C. 



13. This is drawn from another plant in the Prodromus herbarium. It bears the notes — 



(a) " 45. E. hypericifolia (Dum. Cours) Lk. Etiquette originale." 



(b) " Eucalyptus hypericifolia, Dum. (Manus Ottoni)." 



(c) "Mr. Otto, 1826, Jardin de Berlin (Manu Seringei Conservatori)." 



The upper surface of this leaf shows channelling, and the plant is what we now know as 



E. cnem-ifulia, D.C. 

 14a. Juvenile leaf; 146, mature leaf; 14c, 14<:^, anthers; 14«, fruits of "Narrow-leaf." Hog Bay, 



Kangaroo Island, S.A. (J.H.M.) 

 15a. Buds, with calyx broader than operculum ; 156, fruits. These were from a different individual to 



14, but the species is the same. From same place and date. 



16. Twig of E. myrtiformis, Naudin. Villa Thuret, Alpes Maritimes, France. (Cult. Naudin.) 



E. marginata, DC. 



17. In Part VIII, fig. 1, pi. 40, a seedling of E. calophijlla, R. Br., was depicted as E. marginata, Sm., 



through inadvertence. A figure of a seedling of E. marginata, Sm., is now given. 



The seedling of this species is different to that of any other species of the genus with which 

 I am acquainted, in the matter of its mainly subterranean petioles (which in some cases are 

 three in number). 



The seedling is described in the following passage, but it will be observed that there is no 

 reference to the subterranean petiole, nor does the figure show such : — 



" The long petioles show a transition to a still more remarkable type occurring in 

 E. marginata (fig. 343), in which the hypocotyl is subterranean and extremely short, while this 

 deficiency is compensated for by the length of the petioles. The lamina is obcordate, cuneate 

 and trinerved, resembling a Brassica." Lubbock " On Seedlings," i, 526. 



The backs of the cotyledon leaves show a slight purple tint. 



The hypocotyl is, in this species, a mere thickening at the " root-commencement," and at 

 this point the distance of the insertion of the petioles of the cotyledon leaves to the ground-line 

 is considerable. As a rule, th(! hypocotyl, or hypocotyledonary portion of the stem, is measured 

 from the ground-line to the insc^rtion of the petioles of the cotyledon leaves.
