AUTHENTIC CYPERACEX OF LINNEUS. 3807 
and containing two good complete specimens; one is Pycreus 
polystachyus, Beauy., the other is Cyperus malaccensis, Lam. 
Linneus cites two plates fur his C. odoratus, viz. Sloane, t. 74. 
fig. 1, and t. 8. fig. 1. As regards the first of these plates, 
cyperologists are not agreed to what section it refers; some 
Suppose it to represent a Mariscus near M. strigosus; others 
suppose it to represent a Diclidium and to be equal to or near 
Cyperus ferax, L. C. Rich. As regards Sloane’s other plate, t.8. 
fig. 1, it doubtless represents one of the Papyri near C. gigan- 
teus, Vahl. 
As to Sloane, t. 74. fig. 1, the spikelets appear to me much too 
broad for any Diclidium. It is true that, in the older stages of 
Diclidium, the glumes stand out very stiffly and the spikelets 
are then in outline broad, though the outline is very broken ; 
but Sloane’s plate represents the glumes very closely imbri- 
cated; in the young state of Diclidium (Cyperus ferax, L. C. 
Rich.), before the glumes spread, the spikelets are linear. 
Cyperus odoratus, Linn., is (mihi) nomen omnino delendum. 
Cyperus compressvs, Sp. PI. ed. 1, p. 46, n. 11. 
One sheet, marked “ Cyperus compressus ” in Linneeus’s hand, 
is C. compressus. _ 
Cyperus compressus, Linn., is altogether (as to diagnosis, picture 
cited, authentic example) Goon. 
CYPERUS FLAVESCENS, Sp. Pl. ed. 1, p. 46, n. 12. 
One sheet, marked “12. flavescens” in Linneus’s hand, is 
Pycreus rivularis, a North-American sp. nearly allied to the 
European Pycreus flavescens, Nees. Boott has consequently in 
MS. in the Mus. Brit. named some of the American plant Cype- 
rus flavescens, Linn. , 
From the citations it is clear that Linneus meant the European 
Pycreus flavescens, Nees, for his species. Under Pycrreus Fra- 
vescens, Wees, I cite accordingly Cyperus flavescens, Linn. Sp. 
P). ed. 1, p. 46, neque herb. propr. 
Cyprrus pumitvs, Sp. Pl. ed. 2, p. 69, n. 17. 
One sheet, named “ Cyperus humilis” in Linneus’s hand, but 
the word “humilis” struck out and “ pumilus” substituted, 
also by Linneus’s hand, contains two specimens. One of these 
I take to be original and is Pycreus nitens, Nees (= C. pumilus, 
Linn.). The other specimen is marked “‘ Hort. Fothergill, 177s.
