SHORT NOTES. 55 



conservatories and a museum. The collection consists principally 

 of plants arranged and classified under their natural orders ; 

 amongst the well-developed trees in various parts of the Garden 

 are specially to be noticed — Cdtis aitstralis, Sophora japonica, Melia 

 Azedarach, Catalpa Bungeana, Diospyrm virginiana, < BrcisSiUquastrum, 

 Gleditschia horrida var. inermis, G. triacanthos, and G. caspica. 

 There is a bust of Linnaeus in the grounds, and also statues of 

 Quer (the first Director of the Gardens), Clemente, Lagasca, and 

 Cavanilles. The herbarium, which is in the Museum, together 

 with the botanical library, consists principally of the collections of 

 Cavanilles, Eodriguez, Lagasca, and Clemente, all of whom were 

 formerly connected with the Gardens. They are arranged and 

 perfectly accessible, and contain a very large proportion of the 

 types of the species accredited to those distinguished botanists. 

 Besides these, there are the plants gathered by Kuiz and Pavon in 

 Peru, Mo9ino and Sess6 in Mexico, and Mutis in New Granada ; 

 but the collections of Mogino and Sesse and Mutis remain 

 apparently in the boxes in which they were sent home, and 

 seem to be unarranged. A series of drawings by Mutis, numbering 

 6701, of folio size, the greater proportion in colours, form a most 

 valuable contribution to the knowledge of the Flora of the New 

 Granadan region of South America. They are classified, and to 

 some extent named. There are also some inedited Euiz and Pavon 

 MSiS. and drawings, and one of the rooms in the Museum is 

 devoted to a fruit collection, which is used for teaching purposes. 

 I have to thank Sig. Colmeiro, the present Director, for his kind 

 permission to work at the herbarium. — E. G. Baker. 



The Date of Eivinus' Tetkapetal^s (Journ. Bot. 1891, 310). 

 The Editor has done well in pointing out an error of mine as to 

 the date of the work named above. He quotes me as giving, in the 

 Flora Franciscana, the year 1690 for the Tetrapetalae, and leniently 

 suggests that I "may have access to an edition not recorded by 

 Pritzel, who gives 1691 as the date of publication." Upon looking 

 up this matter anew, I find myself to have taken the date 1690 from 

 the general title at the beginning of the volume as a whole ; and 

 that the actual date of that part which embraces the TetrapetalaB 

 is, as Mr. Britten suggests, 1691. As to the "17" of my citation, 

 it need only be said that there are no pages of letterpress either 

 accompanying or devoted to the plates. The only pages, after the 

 preface, are those of the plates ; and upon these no numbers are 

 printed. But even so extensive and important a w r ork as Jaequin's 

 Icones is in the same case. One is obliged to go through the work, 

 and write the whole six hundred and forty-eight numbers, in pen 

 or pencil, for himself. Everyone does that, and the work is con- 

 stantly quoted by number of the plate. I have done the same with 

 my Kivinus, and cite him in the same way. Trifolium repens is the 

 seventeenth in the succession of his figures under the Tetrapetalae 

 heading. — Edward L. Greene. 



[We venture to think that Prof. Greene's mode of citation is 

 open to objection. A number following the title of a book is always 

 assumed to refer to a page of the work quoted : thus Prof. Greene,
