128 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Hordeum flosculis omnibus hermaphroditis, involucris flosculos crassitie & 
longitudine superantibus. Gron. Fl. Virg. 1: 13. 1739. 
Clayton, no. 446. This is cited by Linnzeus under Elymus virginicus. The Clayton 
specimen could not be found. 
Coix seminibus ovatis. Linn. Hort. Cliff. Gron. Fl. Virg. 1: 114. 1739. 
Clayton, no, 67. This is cited by Linneus under Coir lachryma jobi. The speci- 
men in the British Museum is a species of Carex labeled (. folliculata. Gronovius’s 
further description, **Gramen Lacrymae Jobi affini, fructu in spicam congesto,”’ ap- 
ples to this specimen of Carex, and we may consider it an error of determination. 
Coix seminibus angulatis. Linn. Hort. Cliff. Gron. Fl. Virg. 1: 114, 1739. 
Clayton, no. 445, This is not cited by Linnzeus in the first edition of his Species 
Plantarum. In the second edition he cites Gron. 144 [error for 114] under Tripsacum 
dactyloides. Clayton’s specimen is Tripsacum dactyloides (1..) L. 
Cenchrus capitulis spinosis tomentosis. Gron. Fl. Virg. 1: 122. 1739. 
Clayton, no. 206. This is cited by Linneus under Cenchrus tribuloides. The speci- 
men is Cenchrus tribuloides LL. (C. macrocephalus (Doell) Seribn.), the large-burred, 
maritime corm and not the inland C. carolinianus Wait. 
Andrapogon pedunculis conjugatis in medio pilosis, cite. Roy. prodr. Gron. FL. 
Virg. 2: 132. 1743. 
Under this are included two plants: 1. “Gramen ischaemum spicis plumosis 
aristatis, efoliorum alis exeuntibus.”” Clayton, no. 460. This is Andropogon virginicus 
L. In the Species Plantarum (page 1046. 1753) under Andropogon virginicus Lin- 
nus cites Roy. lugbd. as above and Gronovius by page only, omitting the Grono- 
vian diagnosis. 2. “ Lagurus spicis inter folia brevia ad culini summitatem dense fasci- 
culatim congestis,’? Clayton, no. 606,¢ which is Andropogon glomeralus (Walt.) B.S. P. 
This is not cited by Linneus. Gronovius cites the same specimen under Lagurus 
spicis oblongis, etc., page 135. 
Andrapogon spicis conjugatis, calycibus hirsutis. Roy. prodr. Giron. Fl. Virg. 
2: 183. 1743. 
Clayton, no. 602. This is cited by Linnzeus under Andropogon hirtum. The speci- 
men is Andropogon scoparius Michx. 
Andrapogon culmo paniculato. Gron. Fl. Virg. 2: 133. 1743. 
Clayton, no. G01, This is cited by Linnzeus under Andropogon alopecuroides. The 
specimen is Erianthus divaricatus (L.) Hitche. (#. alopecuroides (1..) Ell). 
Andrapogon foliis arundinaceis. Gron. Fl. Virg. 2: 133. 1743. 
Clayton, no. 687. This is not cited by Linneus. The specimen is Brianthis con- 
tortus Ell. 
Andrapogon folio superiori spathaceo, pedunculis lateralibus oppositis uni- 
floris aristis globosis. Gron. Fl. Virg. 2: 133. 1743. 
Clayton, no. 621. This is cited by Linnzeus under Andropogon nutans, the last 
word of the diagnosis being changed to fleruosis, as globosis is an obvious error. He 
“There are two sheets marked with this number. The first is Andropogon glomeratus 
(Walt.) B.S. P. It is referred to by Gronovius (page 132) under *! Andrapogon pedun- 
culis,’”? ete., Roy. prodr., and again (page 135) under ‘ Lagurus spicis oblongis’’ ete., 
Linn. Hort. Cliff., the Clayton diagnosis being the same in the two cases. ( Laquris 
spicis inter folia brevia ad culmisummitatem dense fasciculatim congestis, Clayton, 6067’). 
The second is Panicum virgatum L. referred to by Gronovius (p. 133) under ‘* Pani- 
cum paniculatum glumis acutis,”’ with the Clayton diagnosis, “‘Gramen miliaceum 
altissimum,’’ ete. In the second edition of the Flora Virginica Gronovius disposes of 
the two specimens in the same way, except that he omits the citation of the page 
under “ Andrapogon peduncutis,” ete.
