4. NAP^EA, Clayt. GLADE MALLOW. 



Calyx naked at the base, 5-toothed. Flowers dioecious ; the stamin&le flowers 

 entirely destitute of pistils, with 15-20 anthers ; the fertile with a short column 

 of filaments but no anthers. Styles 8-10, stigmatic along the inside. Fruit 

 depressed-globular, separating when ripe into as many kidney-shaped 1 -seeded 

 beakless and scarcely dehiscent carpels as there are styles. Radicle pointing 

 downwards. A tall and roughish perennial herb, with very large 9 - 1 1 -parted 

 lower leaves, the pointed lobes pinnatifid-cut and toothed, and small white flow- 

 ers in panicled clustered corymbs. (Named by Clayton from vanr), a wooded 

 valley or glade, or, poetically, the nymph of the groves, alluding to the place 

 where he discovered the plant.)

 southward to the Valley of Virginia, west to Ohio and Illinois ; rare. July. 



5. SIDA, L. SIDA. 



Calyx naked at the base, 5-cleft. Petals entire, usually oblique. Styles 5 or 

 more : the ripe fruit separating into as many 1 -seeded carpels, which remain 

 closed, or commonly become 2-valveA at the top, and tardily separate from the 

 axis. Embryo abruptly bent ; the radicle pointing upwards. Stigmas termi- 

 nal, capitate. Flowers perfect. (A name used by Theophrastus.)

 river-banks, Penn., Muhlenberg. Kanawha Co., Virginia, Rev. J. M. Brown. 

 (Cultivated in old gardens.) 



2. S. Elliottii, TOIT. & Gray. Nearly glabrous (l-4 high); leaves 

 linear, serrate, short-petioled ; peduncles axillary, 1 -flowered, short ; /lowers (yd-

 cles axillary, 1 -flowered, shorter than the petiole ; /lowers (yellow) small ; nii-fxln 

 5, combined into an ovate fruit, each splitting at the top into 2 beaks. A little tu- 

 bercle at the base of the leaves on the stronger plants gives the specific name, 

 but it cannot be called a spine. Waste places, common southward and 

 eastward. (Nat. from Trop. Amer. or Afr.)
