24. Kudge4na, G. F. W. Meyer (.V. bldnda, Planch., 

 not of gardens). Lvs. elliptic to suborbicular, 18 in. 

 long, margin coarsely and irregularly sinuate-dentate: 

 fls. 'i-G in. across, imperfectly open 2 or 3 nights from 

 twilight until dawn. Usually only the sepals and 4, 8 or 

 12 outer petals open, the remaining parts forming a 

 closed ovoid bud; occasionally a slight aperture is 

 formed by drawing apart of the tip of the bud, which 

 occurs before midnight. Petals usually 16-20; stamens 

 43-83. Trop. Amer. Flora Erasiliensis 77, pi. 32, 34, ^5,

 and closes again between 3 and 6 a.m. the first night; 

 the second night the sepals and outer row of petals open
