 these the above description is taken. Fl. March-May ; bright chrome

Bryophyllum calycinum, Salisb. (C. P. 541) is a common plant on 

 bare rocky places throughout the low and lower montane country, and 

 has all the look of a native. It occurs in similar places throughout the 

 Tropics, but is believed to be originally from Trop. Africa. Mrs. Walker, 

 in her tour in 1837 (Hook. Journ. Bot. ii. 242), says it had been then in- 

 troduced only 'a few years ago.' It is called 'Akkapana,' or ' Rata- 

 gowa' by the Singhalese, and is recorded by Moon in 1824 (Cat. 32) as 

 Cala?ichoe pinnata, with Colombo as the locality.
