1918] Blake,— Notes on the Clayton Herbarium 51 
angustifolia &c., referred to this species by Linnaeus, is not identifiable, 
and the name must rest on Clayton’s specimens, on which the Grono- 
vian reference was based, and on the specimens in the Linnaean 
Herbarium. Clayton’s plants (nos. 36 & 333), now in the British 
Museum, are not the species now called O. fruticosa, but are O. linearis 
Mx. Fl. i. 225 (1803). In the Linnaean Herbarium the species is 
represented by a single sheet bearing a large specimen and a fragment 
of O. linearis, in addition to a fragment of the upper portion of a stem 
of the plant now treated as O. fruticosa var. hirsuta Nutt. Under 
these circumstances it becomes necessary to adopt the name O. 
FRUTICOSA L. for the plant we have been calling Oenothera linearis, 
which necessitates: the following transfer: O. FRUTICOSA L. var. 
Eamesii (Robinson) Blake (0. linearis Michx. var. Eamesii Robinson, 
Ruopora x. 34 (1908)). 
The earliest name clearly referring to a form of the O. fruticosa of 
our manuals, among the many that have been referred by one author 
or another to this species, seems to be O. HyBRiDA Michx. FI. i. 225 
(1803), the type of which in the Michauxian Herbarium at Paris was 
identified by Prof. Fernald in 1903 as O. fruticosa L. var. hirsuta 
Nutt. (in Torr. & Gray, Fl. i. 496 (1840)). The name O. HYBRIDA 
Michx. must now be taken up for that plant. Of the earlier names 
which have been synonymized with O. fruticosa (in the older sense), 
O. mollissima Walt. Fl. Carol. 129 (1788) seems to have been O. laci- 
niata Hill (1768), as the only specimens in the Walter Herbarium 
agreeing at all well with his description are of this species; O. florida 
Salisb. Prod. 278 (1796) is a mere renaming of O. fruticosa L.; O. tetra- 
gona Roth, Cat. Bot. ii. 39 (1799), is scarcely identifiable from descrip- 
tion, as it may have been either O. hybrida (O. fruticosa var. hirsuta 
Nutt.) or one of the pubescent species such as O. pratensis (Small) 
Robinson; and O. chrysantha Michx. |. c., referred to this species by 
Léveillé in his monograph of the genus, is correctly identified in the 
Index Kewensis with 0. pumila L., as is shown by Prof. Fernald’s 
later determination of the type. 
For the less pubescent or subglabrous form, which has been treated 
as true O. fruticosa by most writers, the earliest varietal name seems 
to be O. fruticosa B. ambigua Nutt. Gen. i. 247 (1818), described 
as “more or less pilose;....leaves lanceolate, or ovate-lanceolate, 
acute, subdenticulate, petals obcordate, longer than broad;....cap- 
sule subsessile, always smooth, oblong, and 4-winged,” and said to be
