A. africana caulescens, foliis glaucis caulem am- 
plectentibus spinosis. Comm. Pr. t. 19. 
Obs. This is the loftiest of the Aloes : I have 
seen it near 20 feet high. It is also the roughest- 
leaved.

tibus; supra laevibus; infra irregulariter spinosis.

A. africana caulescens foliis glaucis caulem ara- 
plectentibus : dorso spinoso, Comm. Pr. t. 20. 
Hort. 2. t. 13. 
Obs. This species and the last never produce 
any onsets, and very rarely flower. 
Aloe foliis oblongo-acuminatis glaucis ; junioribus 
patulis; seniori us horizon talibus : lateribus dor- 
soque interrupte spinosis ; spinis latissimis fulvi- 
cantibus. 
Obs. This species is not much unlike the figure 
of Dillenius's A. mitrcsformis, but the spines are 
not of the same colour. 
A loe foliis ovato-oblongis acutis virescentibus : mar- 
ginibus carinaque valde spinosis ; spinis longis ; ju- 
nioribus albissimis ; senioribus apice flavicantibus. 
Habitat ad Cap. Bon. Sp. 
Obs, This is a very fine species, and the largest- 
spined of all the genus. It never produces any 
offsets, and has not yet flowered in Europe.
