4. P. IVarei (Nutt.) : leaves on short biglandular petioles; the lower ones 

 3-lobed, acute ; the upper ovate, undivided ; siipules none; peduncles com-

East Florida, Mr. A. Ware. — Lower part of the stem suberose. Leaves 

 smooth and sliining, thin. Berries about tlie size of a pea, purple. Nutt.— 

 This species is wholly unknown to us. 



P. peltata (Cav.) is doubtless not a native of the United States. 



Order LX. CUCURBITACEiE. Juss. 



Calyx 5- (rarely 6.) toothed ; the limb sometimes obsolete. Petals 5 

 (rarely 6), distinct, or commonly more or less united with each other 

 and coherent with the calyx, very cellular and often marked with 

 reticulated veins. Stamens 5, sometioies distinct, commonly united 

 in 3 parcels (two and two, and one separate) so as to appear like 3 

 stamens only, rarely 3 and diadelphous : filaments of each set some, 

 times connate : anthers usually long and sinuous, or variously con- 

 torted or folded, 2- celled, adnate, extrorsc, commonly more or less 

 connate. Ovary coherent with the tube of the calyx, usually of 3 

 (rarely of 2 or 4) united carpels, sometimes 1- celled by the oblitera- 

 tion of the partitions, or often with each carpel spuriously 2- celled 

 by the introllcxion of the placentae from the axis until it reaches the 

 dorsal suture. Fruit fleshy or juicy, rarely membranous, usually a 

 pepo.* Seeds anatropous, compressed, often enveloped by a juicy or 



* A pepo is doubtless correctly defined by Arnott to bo " a fleshy inferior fruit, 

 either indebisccnt or bursting irregularly, and consisting of about 3 carpels, each 

 of which is divided into two cells by its piaccntiferous margin being so introflexed 

 as to reach tlie dorsal snturo. Tiie sides of the carpel [the dissepiments], and 

 even sometimes the introflexed portion, usually become extremely thick and fleshy, 

 forming the great mass of the ripe fruit, so that by losing the general character of 

 dissepiments, they might almost be said to disappear; and thus at lirst sight a 

 pepo would be said to be, and has been so described, a l-celled, fleshy, indehiscent
