AMERICAN GRASSES DESCRIBED BY LINNJEUS. 121 
Poa capillaris L. Sp. Pl. 68. 1753. 
The type specimen, from ‘K,’’ is Hragrostis capillaris (L.) Nees. The Gronovius 
specimen incorrectly cited by Linnzeus (Clayton no, 580) is Eragrostis pectinacea 
(Michx.) Steud. . 
Poa ciliaris L. Svst. Nat. ed. 10. 2: 875. 1759. 
The type specimen, from “Br,” is Eragrostis ciliaris (L.) Link. Linneeus@ cites 
Sloane’s plate of Sporobolus indicus under this. 
Briza eragrostis [.. Sp. Pl. 70. 
The type specimen, from MK “is Eragrostis megastachya (Koel.) Link. The 
Gronovius reference (Clayton no. 582) is the same. Both are the more compact- 
panicled form. Linngeus’s specimen of Poa eragrostis L. Sp. Pl. 68. 1753, from Europe 
is the form with more open panicles, but has the same large spikelets. The European 
botanists (e. g. Ascherson and Graebner, Syn. Mitteleurop. Fl. 2: 372.1900.) consider 
Poa eragrostis L. to be the allied species (Eragrostis minor Host) with smaller, gland- 
less spikelets, and quite open panicle. Though the Linngean specimen is Eragrostis 
megastachya, yet the name Poa eragrostis may perhaps be considered as applicable to a 
traditional species rather than to the specimen in his herbarium, This is a question 
which European botanists will doubtless be prepared to decide, It seems to me, 
however, that the description applies better to his specimen (‘‘spiculis serratis decem- 
floris”) than to Eragrostis minor, 
Uniola paniculata L. Sp. Pl. 71. 1753." 
The type specimen is marked ‘ Uniola 1,’’ that is, the first Uniola described in the 
Species Plantarum. It belongs to this species as generally understood. Linnzeus 
cites Gronovius, ‘‘ Uniolacalycibus polyphyllis.”” In the first edition of Gronovius 
this citation is based upon a reference to Hortus Cliffortianus and not upon a Clayton 
plant. In the second edition a Clayton plant, no, 909, is mentioned, but this number 
could not be found in the British Museum. There is no doubt, however, as to the 
identity of the plant; it is the same as that of Linngeus. Gronovius refers to a figure 
of Plukenet and gives the common name ‘‘sea-side oat.’’ 
Uniola spicata L. Sp. Pl. 71. 1753. 
The type specimen, from “ K,”’ is Distichlis spicata (L.) Greene. Aiter his diagnosis 
Linneeus cites Clayton no. 507, but this is Sporobolus virginieus (L.) Kunth, Linngeus 
had already cited this number of Clayton under Agrostis virginica, 
1753. 
Dactylis cynosuroides L. Sp. Pl. 71. 
The Linngean specimen, which is the type, is from Gronovius and is marked with 
the number 577 and accompanied by Gronovius’s diagnosis. Gronovius’s plant cited 
by Linneeus (Clayton no, 577) is the same, namely, Spartina polystachya (Michx.) Ell. 
and should be called S. cynosuroides (L.) Willd. ¢ 
Linnzus subjoins a variety £8 based on a Gronovian citation. The corresponding 
plant, Clayton no. 583, is Spartina glabra Muhl. 
A second sheet pinned to the Linnean plant mentioned above (no. 577) is marked 
by Linneus ‘1,’ that is the first species of Spartina. There is also a label attached 
which says “ Phalaroides spicis inearibus subternis terminalibus secundis adpressis. ”? 
This citation is from Loefling.@ The plant appears to be Spartina stricta of Europe, 
and is probably the basis of the European habitat. (Linnzeus gives as habitat, © Vir- 
ginia, Canada, Lusitania.’’) There is no evidence of his having seen a plant from 
Canada. Linnzeus’s diagnosis ‘‘spicis sparsis secundis scabris numerosis’? applies to 
the first Gronovian plant cited rather than to cither of the others.
