146 MASSON’S DRAWINGS OF SOUTH AFRICAN PLANTS. 
vol. ix., of Pterygodium volucris and P. inversum. On all these <— 
ings, save the last two, is a note in Robert Brown’s hand, ‘returned _ 
April 11, 1820,” the words ‘‘by Mr. Ker’ being added in two in- 
stances. This last fact is of some interest, inasmuch as, although 
the series of papers which these plates illustrate is correctly attri- 
buted to Ker, his name does not appear in connection with any one 
of them, while in the Royal Society’s ‘Catalogue of Scientific 
Papers’ they are assigned to Masson. the Orch 
have been seen by Prof. Reichenbach, and bear names in his hand- 
writing i 
which he queries as S. striatum Thunb. A list of them was given 
by Lindley in Bot. Reg. (tt. 700-703), who says “ The original 
drawings are in Mr. Brown’s library.”’ Py 
There are several drawings of Iridace@, mostly species of Morea, 
four of which were reproduced by Ker in the ‘ Botanical Magazine,’ 
and have been named by him. These are Morea angusta (Bot. 
Mag., t. 1276), M. crispa (Id., t. 1284), M. spicata (Id., t. 1283), and 
Aristea melaleuca (Id., t. 1277); Ker (or Gawler, as he then was) 
acknowledges his indebtedness to Sir J oseph Banks ‘for his very 
liberal permission to copy the original drawings” of these plants | 
(Id., t. 1276). The last-named plant is of special interest, as it is 
the type of Salisbury’s genus Cleanthe (Trans. Hort. Soe. i. 312), a 
genus retained by the authors of the ‘ Genera Plantarum,’ who say 
of it: “ Species 1, Africe australis incole, a nobis non visa. Thunb. 
Diss. Morea t. 1 (Morea melaleuca). Bot. Mag. t. 1277 (Aristea). 
Genus non nisi ex his iconibus et descriptionibus notum, dubium 
remanet.’” Masson’s specimens, however, exist in the British 
undulata 
The drawings of four species of Mesembryanthars tan 1% 
of interest. O ut st of these—as indeed of nearly all 
the plants figured—we have Masson specimens in the British 
Museum. In ey’s ‘ Flora Cupensis’ and elsewhere the nam 
with nineteen other species, in a paper ‘ Descriptiones Mesem- 
bryanthemorum’ appended to vol. viii. of the ‘Nova Acta 
Ephemerides.’ This volume is dated 1791; but in Aiton’s ‘ Hortus 
Kewensis’ (1789) we find the same plants, one, M. ciliatwm, bearing 
the same specific name; the other, M. digitiforme Thunb., called 
nd . digitatum. A reference to the Solander manuscripts shows that
