Column low, usually much broader than high, base and disk broad- 

 er ; the disk broadest, dilated, and thrown into four or five lobes or

 large, rounded, 1 '5 lines broad, yellow or red. ISTaked portion of disk

Color variable; " one variety has a royal smalt-color, with the papillaa 

 of the surface a fine ultramarine, the disk a paler blue, and the mar-
