 borne up n stout footstalks, which are pale green, mottled and 

 striped with zigzag bands of dark green. A. 4ft. or more. Philip- 

 pine Isles, 1862. 



AIiOE (from Alloeh, its Arabic name). Allied genera : 

 Apicra, Haworthia, Pachidendron, Phylloma. Including 

 Rhipodendron. OKD. Liliacece. This hitherto much confused 

 genus, and its allies, have been completely revised by Mr. 

 J. G. Baker (vide "Journal of the Linnean Society," 

 vol. xxviii. pp. 152 182), to whose account we are in- 

 debted for many of the following particulars : Plant with 

 or without stems ; shrubs or (rarely) trees ; leaves thick, 

 fleshy, frequently in a rosette ; peduncles simple or racemed, 

 endowed with few or many empty bracts. Flowers racemed ; 

 pedicels bracteated at base, solitary ; perianth-tube straight 

 or slightly recurved ; segments elongated ; stamens hypo- 

 gynous, as long as the perianth, or longer. Mr. Baker 

 describes over eighty species, many of which, for various 

 and important reasons, have no claim upon our space. 

 Natives of the Cape of Good Hope, except where otherwise 

 stated. These very interesting and curious plants thrive 

 well in a mixture of open loam and peat, together with a 

 small quantity of well decomposed manure. If old brick 

 rubbish, or any other similar material is mixed with the 

 soil to ensure perfect and rapid drainage, so much the 

 better. Water, especially during winter, must be carefully 

 administered. They thrive in an ordinary greenhouse, and 

 cannot have too much light at any time.
