228 TREES AND SHRUBS. 



Though we have received during the last two years much additional material of the group Coronarise, it is not yet sufficient to 

 arrive at a clear understanding of the numerous forms of this polymorphic group. It may be useful, however, to give here a key 

 to the species as they can be distinguished with our material, and under the several species an enumeration of the specimens in

 saves glabrous at maturity ; calyx glabrous or more or less villose in No. 2 and in varieties of No. 4 and 6. 



Leaves distinctly lobed, at least those of vigorous shoots ; those of flowering branchlets usually incisely serrate or lobed. 

 Leaves of shoots cordate at the base with the lowest pair of veins springing directly from the base, glabrous nearly 



from the beginning, light green on the lower surface. 1. M. glabrata. 



Leaves truncate or rounded, the lowest pair of veins some distance from the base, more or less villose when they 



Leaves glaucescent beneath, thickish at maturity; calyx-tube thinly villose. 



Leaves light green on the lower surface, rather thin ; calyx-tube glabrous. 



Leaves serrate, not lobed, or sometimes slightly lobed at the end of vigorous shoots. 



Leaves oval or elliptic, acute ; fruit much depressed, up to 5.5 centimetres in diameter. 4. M. platycarpa. 



Leaves lanceolate, acuminate, thin ; fruit subglobose. 5. M. lancifolia. 



Leaves crenate-serrate, rounded at the apex, usually not or only slightly lobed and cuneate at the base, assuming a brown 

 color in drying ; fruit subglobose. 6> M . CO ronaria. 



ives tomentose or villose at maturity, at least those of vigorous shoots, thickish and strongly veined. 



Calyx glabrous outside; pedicels with conspicuous bracts and bractlets; leaves usually only slightly lobed, generally 



ovate; those of the flowering branchlets glabrous or nearly so. 7. M. bracteata. 



Calyx tomentose or pubescent on the outside; pedicels usually without or with inconspicuous bractlets; leaves usually 



incisely lobed, generally oblong-ovate, all more or less densely pubescent or tomentose beneath, rarely glabrescent.
