The Aloes constitute a genus to which much attention has 

 lately been given, resulting in the discovery of new species

 A plant long known as A. Salm Dyckiana proves undescribed, 

 and is now called A. platylepis; there is also a variety lutea. 

 Aloe cfeaia var. elatior is quite a distinct species, and now to 

 be called A. drepanophylla. For several years a beautifully 

 spotted kind has been grown without name in gardens, though

 a splendid new form; the leaves are long, curving to the apes 

 with large spines, and light green in colour with bars of pale 

 spots. The first results, we believe, of hybridising Aloes may 

 here be seen. One is exactly intermediate between its parents
