 County, 7,000 to 9,500 feet, rich moist soil usually in open coniferous 

 forests, June to September. Montana and Idaho to New Mexico

 Apache County to Coconino County, 7,000 to 9,000 feet, mountain 



meadows, June and July. Wyoming to New Mexico and northern

119. CUCURBITACEAE. Gourd family 



Plants herbaceous, annual or perennial; stems with tendrils, trailing 

 or climbing; leaves simple or compound; flowers mostly unisexual, 

 regular or nearly so, solitary or in racemose or corymbose clusters; 

 calyx tube wholly adnate to the ovary; corolla gamopetalous, or of 

 separate petals; stamens commonly 3 and more or less united, free 

 from the corolla or nearly so; fruits various. 



This family comprises numerous valuable plants such as the melons, 

 squashes, pumpkin, cucumber, and gourds. None of the species native 

 to Arizona is of much economic importance, although some of them 

 seem worth cultivating as ornamental climbers. 



Key to the genera 



1. Fruits gourdlike, hard-shelled, not spiny, at maturity 4 cm. in diameter or 



larger, many-seeded; stems prostrate or trailing, with short, relatively stout, 



few-coiled tendrils; leaves large; corolla yellow (2). 



2. Leaf blades reniform, wider than long, very shallowly lobed or with merely 



undulate, dentate margins; staminate flowers in racemes or corymbs; 



calyx tube cylindric, about as long as the corolla 1. Apodanthera. 



2. Leaf blades not reniform, longer than wide, or else palmately dissected; 

 staminate flowers solitary; calyx tube campanulate, much shorter than 

 the corolla . 4. Cucurbita.
