14. Myrtus? (M. commwrns, Heer, No. 17. tab. 2. fig. 21, 22). 

 Appears to have the characteristic venation (thongh not perfectly 



well preserved), as well as the other characters of a Myrtle leaf. It is 

 probably what Heer has called Myrtus communis, but is distinguished 

 by its very obtuse apex from all the varieties of Myrtus communis 

 that I have ever seen. 



15. Vaccinium Maderense (Heer, No. 15. tab. 2. fig. 15, 16). 

 All the specimens of this that I find in Sir C. LyeU's collection are 



very incomplete, but agree well, so far as they go, with the species to 

 which they are referred by Heer, the Vaccinium padifolium, Sm., or 

 Maderense, D.C. 



16. Vaccinium My rtillus'i 



A smaU leaf, well preserved, agreeing accurately with the leaf of 

 the common Whortleberry, Vaccinium MyrtiUus ; a species not now 

 found in Madeira. 



17. Erica arborea (Heer, No. 14. tab. 2. fig. 17). 



These leaves have so little marked character, that the identifica- 

 tion, though very possibly right, does not appear to me quite 

 certain. 



18. Ilea^ Hartungii (Heer, No. 18. tab. 2. fig. 23, 24). 



The evidence on which this leaf is referred to the genus Ilex does 

 not appear to me very conclusive. 



19. Pittosporum (Heer, No. 21. tab. 2. fig. 27). 



Our single specimen of this agrees exactly with the fragment 

 figured by Heer, but throws no additional light on the affinities of 

 the plant, which, to say the truth, appear very uncertain. 



20. Phyllites hymenceoides, C. B. 



A leaf remarkable for its very oblique or unequal-sided shape, 

 which gives reason to believe that it is a lateral leaflet of a pinnated 

 or trifohate leaf. It is very entire at the margin, obtuse at the apex ; 

 the surface appears to have been very smooth and even, no veins 

 visible except the midrib. Has a general resemblance in form to the 

 leaflets of certain tropical Leguminosce, such as various species of 

 Cassia, Hymencea, and Copaifera. I do not know, in the existing 

 Flora of Madeira, any indigenous plant with leaves at all resembling 

 this fossil. The Cassia bicapsularis is undoubtedly an introduced 

 plant in that island, and moreover its leaflets have but a distant re- 

 semblance to the specimens now under consideration. 



21. Phyllites lobulata, C. B. 



Another leaf which appears, from its obKquity and irregularity of 

 form, to have been a leaflet of a compound leaf. It is very obHque, 

 and has a remarkable lobe on one side only. This sort of irregularity 

 is like what is occasionally to be seen in the lateral leaflets of the 

 Anacardiacece ; but I do not know any that it exactly resembles. 



22. Phyllites. 



A leaf of an obovate-eUiptical form, rounded at the end, with veiy 

 entire margins, and venation of the most ordinary Dicotyledonous 

 type. Has no marked characters, but perhaps most resembles the 

 leaf of some Honeysuckles, such as Lonicera CaprifoUum and its 

 allies. Not figured by Heer.
