188 ON A EUCALYPT HYBRID, 



wing. I have received specimens of this form both from the 

 late Mr. Guilfoyle and from Mr. J. Cronin. The yellow anthers 

 contrast well with the filaments. The'calvx-tubes are urceolate 

 and apple-green, and both on account of the contrast of filaments 

 with anthers and calyx-tubes, the effect in the mass is most 

 charming. 



The Rydalmere tree is 40 feet high, and flourishing. In 

 every respect that I can see, it is identical with E.jicifolia var 

 Gidlfoylei and E. calophylla var. rosea Hort., and T am inclined 

 to think that the more reasonable view is to look upon it as a 

 form of E. calophylhi. The habit and size of the hybrid incline 

 to those of E. calophylhi^ while the pink or purple tinge (in con- 

 tradistinction to the scarlet of E . fici. folia), naturally occurs in 

 E. calophylla. 



Size and habit. 



E. calophylla is a huge tree, with gnarled trunk and scrambling, 

 umbrageous branches, the counterpart of the Apple {Angophora 

 intermedia), of Eastern Australia. The size is given as up to 

 150 feet, with a stem-diameter of 10 feet (" Eucalyptographia ") 

 and I am certain this is not exaggerated. 



E. ficifolia, on the other hand, is a small tree; I think it 

 rarely exceeds thirty feet in height, and it is usually erect, and 

 not scrambling'. 



The hybrid may be fairly stated as intermediate in size. 



Seeds. 



Those of E. calophylla are large, ovate, black, flat, and with a 

 raised angle on one face, the edges acute but scarcely winced, 

 the hilum large on the inner face. 



Those of E.jicifolia are of a pale colour, testa expanded at one 

 end, or round one side into a broad, variously-shaped vving(B.ri., 

 iii., 256). The hilum is towards the end of the seed, and 

 furthest from the wins^. 



The seeds of the E. calophylla x E. ficifolia hybrid are flatter 

 than those of E. ficifolia, and also paler in colour. As compared 

 with those of E. ticifolia, thev are a little darker and less winded, 

 but the hilum is more remote from the wing In other words,
