Cucurbita. CUCURBIT ACE.E. 9-39 



for tlic hard-rinded Gourd, used for vessels. But the fleshy fruits of several are acid and purgative 

 (as in Elaterium and Colocynth, valuable in medicine), and so are the roots of all the perennial 

 species. The Megarrhiza-roots of California in this respect, as in size, are like those of Bryony in 

 Europe. 



* Seeds flattened : cotyledons thin, rising out of the ground and foliaceous in germination : fruit 

 fleshy : united calyx and corolla tubular-campanulate. 



1 . Cucurbita. Flowers all solitary, large, yellow. Filaments distinct, but the flexuous anthers 



confluent 



2. Melothria. Sterile flowers racemose, small, yellowish. Filaments and anthers distinct ; the 



cells of the latter straight. Berry small and juicy. 



* * Seeds large, turgid : cotyledons thick and fleshy, remaining under ground in germination. 



3. Megarrhiza. Flowers small, white ; the sterile racemose. Corolla rotate. Fruit becoming 



dry and fibrous, few-seeded.

prostrate and rooting at the joints ; leaves cordate, lobed ; tendrils compound ; 



flowers large, yellow ; fruit often large. 



A genus of half a dozen or more species, from some of which have come by cultivation all the 

 many different varieties of Pumpkin and Squash.
