DESCRIBED BY LINNÆUS ETC. 849 
of which is written “ Commel. Hort. ii. p. 119, t. 60;”? but the 
figure does not represent this plant, and still remains doubtful, 
as I have pointed out (vide supra, p. 345). 
In the cover of Hebenstreitia is a specimen without generie 
name, labelled by Linn:eus “polystachya.” It does not affect the 
description of Selago polystachya, L., and S. spuria, L. 
Species originally published in Linneus ftlius's ‘Supplementum 
Plantarum’ (1781). 
With the exception of Bartsia Gymnandra, L. fi, the whole 
of the following species were described from Thunberg's herba- 
rium, where they still remain in an excellent state of preserva- 
tion. They are therefore the types of Thunberg’s works also. 
P.278. Bartsia Gymnandra, L. fil.! In the Linntean Herba- 
rium is a sheet sent by Pallas, who says, “Lagotis glauca, Gertner, 
mihi in Itinere, vol. iii. nomine Gymnandre descripta. In terris 
arcticis circa Obum in Alpib. Davisie summis in Kamtsch. 
crescit." This sheet consists of a specimen of LAGOTIS GLAUCA, 
Gaertner, in Nov. Comm. Act. Petrop. xiv. p. 553, t. 18 (1770), 
Gymnandra Ganelini, Cham. et Schlecht. in Linnea, ii. p. 561, on 
the right-hand side, and two specimens of Gymnandra borealis, 
Pall., Reise Prov. Russisch. Reichs, iii. p. 710, t. a. fig. 1 (1776), on 
the left-hand side, the plants represented by these figures respec- 
tively. Thus Bartsia Gymnandra, L. fil., represents two plants. 
Lagotis, as the older name by six years, takes the precedence. 
G. borealis, Pall., is L. PArrasirr, Rupr. Sert. Tianschan. p. 64 
(in note). 
P. 284. SELAGO DIVARICATA, L. fil.! One specimen. Choisy 
did not know this species, as he erroneously refers it to S. tri- 
quetra, L. fil. 
S. canescens, L. fil.! There are two sheets labelled “Selago 
canescens,’ one with two specimens on, the other with one, 
which I consider the types, as they agree with the short de- 
scription. On the right-hand side of this latter sheet is a speci- 
men of S. adpressa, Choisy !, whieh is also part of E. Meyer's 
S. tephrodes! (from locality “b” !), a species founded on three 
distinct plants. The S. canescens of E. Meyer! and of Choisy! 
is another plant, which is identical with S. ausina, Choisy in 
DC. Prod. xii. 18. Choisy appears to have called the true 
S. canescens, L. fil., S. glabrata, as he says “v. s.in h. DC. ex 
Thunb. sub falso nom. S. canescens ;" but not having seen Choisy’s
