has enumerated (besides Aloe palustris anglicana which is = Stratiotes aloideg 

 Linn.) twenty-two Aloes- Out of these there are eight belonging to genera other 

 than Agave or Furcrsea which are chiefly true Aloe and received mostly 

 from Africa. 



His first species "Aloe perrara Andalusiae" was obtained from the South 

 of Spain and does not appear to have been taken up subsequently. The remain- 

 der seem to be species (or at least forms) of Agave and Furcrsea: of Ray's 

 species he appears to include the following, 



(1) folio in oolongum aculeum abeunte 



(2) Theometel 



(3) serrata major umbellifera (Hunting) 



(4) purpurea laevis (Hunting) 



also the Caraguata guaqu of Ray, for which however he quotes Piso and calls 

 the plant Aloe americana spinifera, ignoring seemingly the Caraguata and the 

 Caraguata acanga of Markgraf, which Ray had distinguished. He has 

 evidently merged Ray's No. iii serrata umbellifera of M anting in his 

 americana sololifera for which he quotes Hermann (v. sup.). 



He throws some doubt on Ray's identification of Hernandez' " Metl lenissi- 

 mum" on grounds which hardly seem forcible. A variegated kind of Aloe 

 americana is mentioned which was evidently regarded as a form of ''sololifera." 

 "Aloe americana radios tulerosa fcetida major," = Pit or Pita of 

 Parkinson, is quoted as being the " Piet of the natives" [i.e. of the West 

 Indies] and a picture is given in the Phytoc/rapbia. Two varieties are 

 mentioned, one with marginal spines, the other spineless, of which the latter 

 is perhaps a Furcrcea (F. gigantea Vent. ex. Martins Fl. Brasil, III. j>. J. 187.") 



Parkinson's" Aloe [americana foliis ccesiis latiori bus " is doubtfully identi- 

 fied with the " Aloe americana ear Vera Oruce foliis latioribus glaucis " of the 

 Sortus Seaumontianus. We have not been able, unfortunately, to see figures of 

 either, but the brief descriptions pretty surely refer to one or other of the 

 glaucous Euagaves that are now diffused in Europe. 



In the " Institutions " (Lyons ed. 1706) Tournefort has a figure which 

 contrasts the flower of Agave, with that of the true Aloes, but he got no 

 further, and his list of species does not differ materially from that of PluJcenet 

 except that it is briefer. 



In 1696 Sir Hans Sloane, a Fellow of the Royal Society, 

 and afterwards its President, published his Catalog us Plan- 

 tarum as the result of travel, chiefly in the West India Islands. 

 The plants enumerated are those of Jamaica principally, but the 

 book contains many valuable references as regards the Caribean 

 region generally. 



The Catalogue gives only four " Aloes" viz. 



(a) Aloe Dioscoridis 



(b) Aloe secunda seu folio in oblongum aculeum abeunte 



(c) Aloe Yuccae foliis 



(a) Aloe visci in modum arboribus innascens
