 tataXN. Devoniensis, raised at Kew in 1885. B.M. 6988. .Said

 long, margin coarsely and irregularly sinuate-dentate : 

 fls. 3-6 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

 surface reddish brown; petiole with a ring of long hairs 

 at the point of ,joining the leaf: fls. 3-6 in. across, im- 

 perfectly open 1 or 2 nights ; the bud opens about half 

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

 the second night the sepals and outer row of petals open 

 about 7 P. M., the other parts remaining as a tight, 

 white bud until 3.30 a. m., when the fl. opens fully from 

 4.30 to 5 A. M., then closses by 6.30 a. m. and draws down
