 very prominent vertical ribs. h. 4in. to 6in. South Mexico. 

 See Fig. 692. 



E. Ottonis (Otto's), fl. delicate lemon-colour, sessile, in threes 

 or fours upon the summit of t.he stem, with bright red stigmas. 

 July. Plant orbicular-cylindrical, contracted at the base, with 

 about twelve vertical deep furrows; the ridges between the 

 furrows obtuse, studded with rather closely-set small tufts of 

 reddish wool ; from these arise three or four rather strong spines, 

 of a deep purplish-brown colour, which stand forward and are 

 sometimes curved, and several lesser pale-coloured spreading 

 ones. h. 3in. to 4in. Brazil, and probably also Mexico. (B. M.

. peotiniferns (pectinated).* /. pale green, rose, solitary, two

 rotund or ovate, rather suddenly contracted above the middle, 

 depressed and even umbilicated at the top, deeply costate, with 

 about twenty prominent costse, which are obtuse and somewhat 

 mammillose at the margins ; in the centre of each mammilla is an 

 oblong, white, woolly, close-placed areola, with numerous rather 

 short spines, whose arrangement is very peculiar. They are of 

 two kinds ; the greater number spread out almost horizontally in 

 two rows, closely placed in a pectinated manner, whitish or 

 yellowish-white, tipped with red or brown, almost united at their 

 base, the middle ones the longest ; between these two rows are a 

 few smaller ones. k. 4in. Mexico, 1844. A very showy species. 

 (B. M. 4190.) 



E. Pentlandi (Pentland's).* fl. large, in proportion to the size of 

 the plant, springing from the sides upon the ribs, solitary, but
