interesting to find that a smaller sheet, on which Lamarck has 

 written only the word "Chironia," has a solitary specimen of the 

 form of C. jasmmoides which the younger Linnaeus did name 

 G. nudicauks, and that Lamarck has affixed this small carton to 

 his original sheet of C. jasminoides. 



Thunberg in 1794 (Prodr. PL Cap., i., p. 35) enumerated seven 

 species of Chironia from South Africa. In 1803 he prepared a 

 fuller account of these ; this was published (Trans. Linn. Soc, vii., 

 pp. 248-253) in 1804. The information then given was repeated in 

 1813 (Flor. Cap., ii., pp. 107-11 1). The paper printed by the Linnean 

 bociety is accompanied by figures of the two species which the 

 younger Linnaeus published {Supply p. 151) in 1781 from speci- 

 mens that Thunberg had given him. As regards these two species, 

 C. tetragona, Linn. f. (Trans. Linn. Soc, vii., t. 12, fig. 2) and 

 6. nudicaulis, Linn. f. (ibid. t. 12, fig. 3) there is therefore no 

 dubiety. Nor is there any with regard to C. frutescens, Thunb., 

 which is the Linnean species so named, and therefore is Orphium 

 frutescens, E. Mey. The other four species only become intelligible 

 when the actual specimens used by Thunberg are studied ; the kind 

 help of Professor Juel, of Upsala, has allowed of this being done. 



In the Thunberg herbarium, C. baccifera is represented by one 

 sheet with two specimens. These specimens differ slightly ; one 

 represents typical C. baccifera, Linn. ; the other is C. baccifera, var. 

 Burchellii. There is only one sheet marked C. linoides in the 

 Tfc™,i~v u„a__. — the species represented is not C. linoides,

The herbarium of Thunberg has four sheets named by him 

 0. lychnoides. The species present on two of the sheets, a and y, 

 is the well-known garden-plant C. linoides, Linn. The sheet

The description given by Thunberg is rather vague, perhaps as the 

 result of an attempt to cover three species, but it includes one 

 character, " flowers terminal solitary," which renders it applicable 

 only to C. maritima, Eckl. (sheet /3), and excludes the other two. 

 It seems, however, probable that the plant which Thunberg more 

 particularly had in view is not C. maritima, but C. linoides, since 

 this species has supplied half his material, and since he say* of the 

 species which he termed C. linoides, but which is C. gracilis, that 

 it is nearly allied to, and may be no more than a variety of his 

 G. lychnoides. If we could be certain as to this, then C. lychnoides, 

 Thunb., is really the original C. lychnoides, Berg. But even so, 

 the agreement between Thunberg and Bergius is fortuitous, for 

 Thunberg does not cite C. lychnoides, Berg., as a synonym. On 

 the contrary, he quotes C. lychnoides, Linn., and therefore quotes 

 a plant that is not C. lychnoides. Berg., and that differs greatly 

 trom all three species to which " ' " " iU "
