Obs. — Var. y of Revis. PL Succ. p. 204, yet exists 

 at Kew, but in a bad state, and seems to be nearer 

 to Gasteria nitida, where I shall now place it, rather 

 than under the present article. 



The specific name of disticha ought, by right of pri- 

 ority, to remain with the present species, although ap- 

 propriate to many others ; and notwithstanding Linna?us 

 blended with it, as marked varieties, the Gasteria cari- 

 nata (so well figured by Dillenius) ; and even the old 

 Aloe plicatilis figured by Commeline. Sad testimonies 

 these, of the low state of that great man's knowledge 

 in this department of Botany. Nor did Willdenow in 

 his celebrated edition of ihe Species Plantarum explain 

 the old Aloe plicatilis much better; this fine arbo- 

 rescent plant being merely his variety a, (instead of |S 

 with LinnjEus,) and at the very same time also his own 

 Aloe plicatilis; adopted doubtless from Alton's flb?'/?^ 

 Kewensis, although he afterwards erected it into his 

 own genus Rhipidodendron ; retaining still the specific 

 name of distichum: thereby restoring the ancient spe- 

 cific name of Linnajus ; but not the old generic one of 

 the plant; which according to his own account was
