 Twigs and young leaves closely strigillose ; peduncles slightly 

 longer than the petioles. 

 Anterior petals longer than the posterior one ; anterior style longer 

 than the posterior ones. 

 Styles unequal, the 2 posterior ones manifestly longer and thicker than 

 the anterior one. 

 Stamens opposite the lateral petals not longer than those opposite 

 the sepals ; styles more or less swollen at the apex, sometimes 

 hooked in M. punicifolia. 

 Peduncles about as long as the petioles or shorter. 

 Mature leaf -blades glabrous and not reticulate. 

 Drupe longer than wide, 10-16 mm. long. 

 Drupe wider than long, 4-6 mm. long. 

 Mature leaf-blades with coarse scattered hairs beneath, reticu- 

 late above. 

 Peduncles much longer than the petioles. 

 Leaf-blades linear to oblong-linear. 



Leaf -blades oblong to elliptic, varying to broadest above or below 

 the middle. 

 Stamens opposite the lateral petals much stouter than the others and 

 longer than those opposite the sepals ; styles hooked at the apex. 

 Leaf -blades flat, entire. 

 Calyx with 10 glands. 



Peduncle as long as the petiole or shorter. 



Leaf -blades of an oblong type ; drupes less than 1 cm. 



long. 

 Leaf-blades of an ovate type ; drupes over 1 cm. long. 

 Peduncle much longer than the petiole. 

 Calyx with 6 glands. 

 Drupe subglobose. 

 Petals nearly equal. 

 Petals markedly unequal. 

 Drupe pyramidal. 

 Leaf-blades more or less revolute or involute, furnished with 

 bristles on the margins and on the teeth when they are pres- 

 ent, as well as on the surfaces. 

 Leaf-blades undulate or crenulate. 



Petals white or pink ; calyx with 6 glands ; leaf -blades ovate 



or oval-ovate. 

 Petals purple ; calyx with 10 glands ; leaf-blades oblong or 

 lanceolate. 

 Sepals oblong or oblong-lanceolate : twigs and branches 

 dark ; glands about one half as long as the sepal-body. 

 Sepals ovate ; twigs and branches pale ; glands nearly as 

 long as the sepal-body. 

 Leaf-blades sinuate-dentate. 



Leaf-blades membranous or parchment-like. 

 Leaf-blades leathery. 



Blades of the mature leaves glabrous above, pubescent 

 beneath. 

 Calyx 6- or 8-glandular. 

 Calyx 10-glandular. 



Larger petals 8-10 mm. long; leaf-blades much 



longer than wide. 

 Larger petals 4-5 mm. long; leaf-blades mostly 

 about as wide as long. 

 Blades of the mature leaves, except for the marginal 

 bristles, glabrous. 

 Drupe pyramidal, sometimes depressed, mostly less 

 than 7 mm. long ; leaf-blades involutely folded.
