h. A. Hartwe'gi. Flowers on stout peduncles, from a woody base. 

 Divisions of the perianth narrowed to a linear apex. Leaves marked 

 with lighter-colored veins, often white-veined. This grows in the 

 higher parts of the Sierra Nevada Mountains under the trees. 



II. ARISTOLO'CHIA, Dutchman's Pipe

 before or with the leaves, in the leaf axils. Peduncles slender, wdth 

 a leaf-like bract in the middle. Leaves soft, pubescent, ovate-cordate 

 on short petioles. This climbs amid the brush, from which it is not

 species are annuals, much branched, with slender stems. The 

 perennial species are stouter, and one, E. fasciculaHum, is an
