GRASSES OF GRONOVIUS’S FLORA VIRGINICA. 129 
also makes the same citation under Stipa avenacea. In the second edition of the 
Flora Virginica Gronovius refers to Clayton no, 621 under two species, on page 15 under 
Stipa, and on page 158 under Andropogon. The Clayton specimen is Stipa avenacea, 
Panicum paniculatum glumis acutis. Gyon. Fl. Virg. 2: 133. 1743. 
Two specimens are included: 1. Gramen miliaceum altum maritimum foltis Arun- 
dinis. Clayton, no. 578; and, 2. Gramen miliacenm altissimum, panicula omnaum 
maxima sparsa, ete., Clayton, no. 606. Both are Paniewn virgatum, This is cited by 
Linmeus under Paniewm virgatium, with the proper Clayton diagnosis, ** Paniewm pani- 
culatium, glumis acutis Gron, Virg. 183.7? Clayton 606@ is also cited by Gronovius 
under Andrapogon, page 132, but it is a different diagnosis and a different specimen. 
Panicum paniculis simplicibus, culmo ramoso subdiviso. Gron. FI. Virg. 2: 
133. 1743. 
Clayton, no. 458. This is cited by Linneus under Panicum dichotomum, of which 
it is the type. This sheet has two plants, Paniewn dichotomum L. as usually under- 
stood and P. oligosanthes Schult. The description applies better to the former, 
which, therefore, has been selected as the type specimen. For further discussion 
see page 117. 
Panicum spica simplici, aristis aggregatis flosculo subjectis. Gron. Fl. Virg. 
2: 134. 1743. 
Clayton, no. 579. This is cited by Linneeus under Panicum glaveum vy. The 
specimen is Chaetochloa glauca (1..) Scribn. 
Panicum spicis alternis oppositisve linearibus patentissimis muticis, etc. Roy. 
prodr. Gron. Fl. Virg. 2: 154, 1743. °° Crab-grass.”’ 
Clayton, no. 457. This is cited by Linmeus under Panic sanguinale, No speci- 
men could be found. 
Panicum spicis alternis remotis declinatis compositis. Linn. Virid. Gron. Fl. 
Virg. 2: 134. 1743. 
Clayton, no.591. This is not cited by Linnzeus. Under Panicum italicum he cites 
“Gron. Virg. 134,"’ but the diagnosis is different from anything given by Gronovius. 
In the second edition of Gronovius the Clayton number is misprinted 561. ©The speci- 
men is Hehinochloa crusgalli (L.) Beauv. 
Dactylis spicis secundis alternis erectis approximatis, calycibus unifloris 
subulatis. Gron. Fl. Virg. 2: 134. 1745. 
He characterizes this further as ‘‘Gramen maritimum spicatum foliis longis angus- 
tis”, ete. Clayton, no. 583. This is cited by Linnzeus under Dactylis cynosurotdes fs. 
The specimen is Spartina glabra Muhl. 
Gronovius here‘alludes to two other specimens (‘* Hujus Generis sunt”). 1. Gramen 
maritimum spica crassa dactyloide, ete. Clayton no. 577. This is cited by Linnwus 
under Dactylis cynosuroides. The specimen is Spartina cynosuroides (L.) Willd, 
(Spartina polystachya (Michx.) Ell.) 2. Gramen avenaceum locustis argenteis spectosis 
lucidis muticis, uno versu lave dispositis. Clayton no. 553. There is no specimen of 
this and I do not find that it is cited by Linnieus. 
Lagurus spicis oblongis pedunculatis, etc, Linn. Hort. Cliff. Gron. Fl. Virg. 
2: 135, 1743. 
Clayton, no. 606.4 This specimen is cited by Gronovius under the ** Andrapogon”’ 
on his page 132 also. Linnzeus cites it under Andropogon bicorne. The specimen is 
Andropogon glomeratus (Walt.) B.S. P. 
Lagurus humilior, panicula unica laxe nutante, culmum terminante. (ron. 
Fl. Virg. 2: 136. 1743. 
Clayton, no. 600. This is cited by Linneus under Andropogon divaricatum. The 
specimen is Sorghastrum linnaeanwm (Hack.) Nash.
