 4in. to 7in. broad at the widest part ; upper surface rich dark 

 velvety-green, midrib margined with metallic grey ; under side 

 pale green, tinged with red, rib prominent. Brazil, 1866. Very 

 handsome and distinct. 

 Other plants rightly or wrongly referred here in catalogues are :

cultivating where those described above are grown. 



CTANOTIS (from kyanos, bine, and ous, an ear; 

 alluding to the petals). SYN. Tonningia. OED. Comme- 

 linacece. A genus containing about thirty species of 

 pretty stove or greenhouse plants, allied to Tradescantia. 

 Flowers nearly regular; perianth segments six; exterior 

 ones nearly equal, navicular, connate at base; inner three 

 long, petaloid, connate by the claws. Leaves various, 

 small or middle-sized, sheathing at the base. Cyanotis 

 require a rich loamy soil, and good drainage. They are 

 propagated chiefly by young cuttings, inserted in sandy 

 soil, in brisk heat. Several species are enumerated.
