DIVISIONS. APETAL^E. 



ARISTOLOCHIACE^E. 



Twining shrubs or low herbs with perfect flowers, the conspicuous lurid calyx valvate 

 in the bud and coherent with the 6-celled ovary, which forms a. many-seeded 6-celled 

 pod or berry in fruit. Stamens 6-12, more or less united with the style; anthers adnate, 

 extrorse. Leaves petioled, mostly heart-shaped and entire. Gray's Manual. 



ARISTOLOCHIA. 



Calyx tubular, inflated above the ovary. Stamens 6, the sessile anthers adnate to 

 the short stigma. 



A. Californica, Gr. (Pipe-Vine.) A twining shrub with large cordate leaves, 

 flowers curved like a Dutch pipe, greenish, marked with brown or purple. 



2. AS ARUM. Tourn. 



Calyx regular, 3-cleft or parted. Stamens 12, with more or less distinct filaments 

 their tips usually continued beyond the anther into a point. Stemless herbs with creep- 

 ing rootstocks, bearing 2 or 3 scales, then one or two leaves, and terminated by a short 

 peduncled flower close to the ground. 



A. caudatum, Lindl. (Wild Ginger.) The smooth, broadly cordate leaves usually 

 mottled with white; calyx bell-shaped, the acuminate lobes spreading, brownish purple. 

 Common in forests; the flowers likely to be hidden under leaves. 



A. Hartwegi, Watson. Stouter than the last: leaves cordate, mottled margin 

 ciliate: peduncle stout, 6 lines long: calyx-lobes ovate, narrowed to a linear apex 1-1J 

 inches long: anther shorter tnan the appendage or produced filament above.

 Plumas Co. 



NYCTAGINACEJE. 



Herbs with mostly opposite and entire leaves, stems swollen at the joints, the tubular 

 calyx corolla-like, its persistent base contracted, inclosing the 1-celled, 1-seeded ovary, 

 and becoming a sort of indehiscent pod. Flowers with an involucre encasing from one 

 to many flowers.
