conditions of Italian gardens, in his turn undertook a re- 

 vision of Agave, in which (p. 29) A. Besseriana, A. Besseriana 

 Candida, A. fhvescens, A. flavescem macracantha, A. linearis 

 and A. subfalcata are ranged under A. inacracantha; A. corir- 

 cinna is made a variety of the same species; A. pugioni- 

 formis, treated as of uncertain position, is evidently known 

 from description only; A. Karivinskii or Karwinskiana is 

 placed under A. Ixtli (p, 44); and A. Corderoyi, of which ho 

 seems to have examined a young plant, is located next the 

 latter (p. 45). Adding to the difficulties caused by frequent 

 changes and typographical errors in spelling macroacantha, 

 Terracciano treats A. macrantha Todarof as a variety of 

 macracantM, the inflorescence of which was then known 

 only from the seemingly racemose plant figured by Hooker, 

 while Todaro's species is obviously a true Littaea. Terrac- 

 ciano's disposition of earlier references is essentially that of 

 Baker. 



A few years later still, Mr. Bakerf, who had continued 

 his study of the Agaveae, embodied his conclusions in a 

 monograph of the entire group Amaryllideae. The treat- 

 ment is essentially along the lines of his Gardeners' Chronicle 

 revision but lacks the illustrations of the earlier paper, and 

 some conclusions have lost their first keenness of insight. 

 This book was afterwards put into Spanish by Segura§ as 

 part of a publication which has gone through several editions. 

 In the Handbook,— which to-day is the most-used reference 

 work on Agave, — A. macracantha is placed among the Lit- 

 taeas — as it had been placed among the equivalent Gemini- 

 florae by Terracciano, on the misunderstood Botanical 

 Magazine figure. Of it, A. flavescens and A. Bessereriana 

 are considered to be synonyms, and A. subfalcata and ^1. 

 linearis are said not to be specifically separable. A. con- 

 cinna and A. oligophylla are maintained. A. pugioniformis, 

 which Mr. Baker says he had never seen, is still ranged among
