b. 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 



Perianth something like a pipe in shape, inflated, soon 

 deciduous from the inferior ovary. Anthers 6, sessile, adnate 

 to the short style. Stigmas 3-6-lobed. Pod club-shaped.

AX5alifor / nica Torr. A shrubby vine with twining stems. Flowers 

 greenish brown with purplish brown stripes and markings, appearing 

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

 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 

 readily distinguishable, as the colors of the flower are so similar to 

 its surroundings, and usually there are no leaves when the flowers 

 are in bloom. 



POLYGON A'CE-ZE. BUCKWHEAT FAMILY 



Shrubs or herbs. Perianth small, generally corolla-like, of 

 3-6 distinct or united divisions. Stamens 4-9 on the perianth. 

 Ovary a 3-sided or lens-shaped akene, generally dark brown 

 or black. Styles 2-4. 



I. ERIOG'ONUM, California Buckwheat 



Flowers small, perfect, on hair-like pedicels from bell-shaped 

 or top-shaped involucres. Perianth of 6 petal-like divisions, 

 thin in texture, yellow, white, or rose-color. Stamens 9. 

 Styles 3, generally deflexed or curled, with cap-like stigmas. 

 Akenes 3-sided (rarely lens-shaped or winged). Leaves without 

 sheaths or stipules, often more or less white-woolly, generally 

 in a spreading cluster at the base of the stem. The smail 

 involucres full of flowers are variously clustered in umbels, 

 panicles, racemes, etc. 



These plants inhabit dry places. The species are very 

 numerous, and difficult to distinguish. The majority of the 

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

 perennial species are stouter, and one, E. fascicula'tum, is an
