2. E. cosmophylla F.v.M. 



" In some respects they " (the imperfect specimens of E. pachyphylla) " resemble 

 E. cosmophylla and its allies, but the fruit, the seeds, and perhaps the inflorescence 

 are different (B.F1. iii, 237). Let us turn to Part XXI, Plate 91, for E. cosmophylla. 

 In E. cosmophylla the flowers are usually in threes, and the calyx-tubes have usually 

 one rib and the opercula none at all. The fruits differ a good deal, and the anthers 

 still more. E. cosmophylla attains the size of a fairly large tree. 



3. With E. pyriformis Turcz. 



This was first indicated by Mueller in Fragm. x, 5. 



" E. pachyphylla approaches the variety pruinosa of E. pyriformis [such a variety 

 has never been technically defined. — J. H.M. ], but its flowers and fruits are much smaller, 

 almost devoid of a general flower stalk (peduncle), and crowded to the number of about 

 seven together (" Eucalyptographia " under E. pyriformis). For E. pruinosa Turcz., 

 see this work, Part XVII, pp. 230-1. I have not seen the species, but Mueller says 

 E. pachyphylla only " approaches " it. 



There seems no doubt that both Mueller and I are correct in pointing out the 

 affinity of E. pachyphylla to E. pyriformis, and I went so far as to make the former a 

 variety of the latter. Compare figures 5 and 6 (E. pachyphylla) with the rest of the 

 figures on Plates 75 and 76 (E. pyriformis). The anthers are similar, and the chief 

 differences lie in the size of the fruits and in the length of calyx- tube or at least pedicel. 



4. With E. pyriformis Turcz., var. Kingsmilli Maiden. 



The affinity of E. pachyphylla is, however, closer to this variety, but they differ, 

 as regards the larger buds and fruits ; the longer petioles and pedicels ; the more pointed 

 opercula ; the ribs deeper, almost winged and more numerous, of var. Kingsmilli. 



5. With E. Oldfieldii F.v.M. 



E. Oldfieldii is under revision, but Part XVII, p. 223, may be turned to, and 

 figs. 11, Plate 73, and figs. 1 and 2, Plate 74, consulted. All these are close to the 

 type. Both species are Mallees, but in E. Oldfieldii the fruits are in threes, with no 

 ribbing on either calyx-tube or operculum, and the rim of the fruit is domed. 



Fig. 7, Plate 75 (Burracoppin), which I attributed to E. pyriformis var. minor 

 (and specifically identical with E. pachyphylla), of which fruits and a few leaves are 

 alone available, is a form of E. Oldfieldii, with comparatively long stout pedicels. I 

 have a note on it in Joum. Roy. Soc. N.S.W., li, 455.
