Obs. This species and striata are the softest- 

 leaved and most succulent of all the Aloes : the 

 former is the only species whose flowers are yel- 

 low. In the course of my studying this genus, 

 I have found the structure and colour of the 

 flowers, and the position and colour of the leaves, 

 tubercles, and spines, of more consequence, as 

 specific criteria, than the shapes of those leaves, 

 arms, or flowers.
