MACLOSKIE : REVISION OF FLORA PATAGONICA. 195 



2. P. CORIACEA Lag. 



Central and South Chili ; N. W. Patagonia, by Rio Refiihue. 



SCHIZEILEMA Domin, n. gen. 



(In Hooker's Flor. Ant. a subgenus of Pozoa, chiefly found in New 

 Zeal., 2 of its species in S. Patagon.) 



Umbelliferous, with the habit of Hydrocotyle and Huanaca; but the 

 densely compressed mericarps resemble Azorella; whilst the leaf-structure, 

 having no leafsheaths, and the unsegmented pedicel, and large calyx- 

 teeth are unlike Azorella, and more like Huanaca. The fruit is peculiar, 

 prismatically quadrangular, with rounded angles, the side-view narrow; 

 ribs scarcely visible, always 5 (not 3). Exocarp leathery, separable from 

 endocarp. Umbels simple, pedunculate, and flowers mostly pediceled; 

 petals straight, and calyx-teeth half as long; mericarps dorsally com- 

 pressed, and slightly convex. Seed straight, oblong. Plants generally 

 glabrous with reniform or orbicular, simple or lobed leaves, long, stipu- 

 late. The Patagonian species have a carpophore. 



S. RANUNCULUS Dom. n. comb. 

 Syn. Azorella ranunculus d'Urv., Pozoa ranunculus Hook. f. 



Stem slender, repent, small. Exocarp mostly soluble. 

 Falkland Is. 



S. TRILOBATUM Dom. n. comb. 



Syn. Azorella trilobata Dus. Rhizome thicker, shorter; exocarp more 

 cohering with endocarp. Patagonia. 



BOLAX. 



Calyx entire; petals oval, entire. Styles short. Fruit quadrangular, 

 the faces of mericarps concave, jugae 5, smooth, I dorsal; 2 mid-jugae 

 forming the angles. Leaves imbricate, trifid, glabrous, coriaceous ; lobes 

 ovate, obtuse, not ciliate. Umbels simple, subsessile, 4-flowered. Invo- 

 lucral bracts for the pedicels. Young fruits stellately hairy.

Syn. Azorella bovei Speg., described in Macl., p. 627, no. 5.
