306 MR. C. B. CLARKE ON CERTAIN 
Cyperus difformis, Linn., is, as to diagnosis, citation, and 
examples, Goon. 
Cypervs Iria, Sp. Pl. ed. 1, p. 45, n. 8. 
One sheet, originally marked “8. Iria” in Linneeus’s hand, 
but “Iria” struck out and “haspan’’ substituted, also by 
Litneus’s hand, contains two good specimens, whereof one is 
C. Iria, Linn., the other C. diffusus, Vahl. 
The figure cited of Plukenet (Alm. t. 191. fig. 7) is C. Iria; 
that cited of Rheede (Hort. Malab. vol. xii. t. 56) is Juncellus 
tnundatus, Roxb. (sub Cypero). 
This species may be cited :— 
Cyrervs Inia, Linn. Sp. Pl. ed. 1, p. 45 (tab. Rheedei 
citat. excl.), et herb. propr. partim. 
Cyperus ELATUS, Sp. Pl. ed. 2, p. 67, n. 10. 
One sheet, marked “ Cyp. elatus” in Linneus’s hand, is the 
species I have so called in Journ. Linn. Soe. vol. xxi. [1884], 
p- 189, and is called C. racemosus by Steudel and Boeck. ; but I 
regard it as very doubtful what C. racemosus, Retz., really was 
(Arnott considered it to have been O. digitatus, Roxb.). At all 
events, the description of Linneus in the Amen. Acad. vol. iv. 
p- 801, altogether agrees with his authentic specimen; and I 
apply to the plants Wallich 3341 a, Zollinger 350, the name 
CYPERUS ELATUS, Linn. 
CYPERUS GLOMERATUS, Sp. Pl. ed. 2, p. 68, n. 12. 
Two sheets, each marked “ glomeratus ” in Linnzus’s hand. 
Cyperus glomeratus, Linn., is altogether (i. e. diagnosis, figures 
cited, and authentic specimens) Goon. 
CYPERUS ELEGANS, Sp. Pl. ed. 1, p. 45, n. 9. 
One sheet, marked “9. Cyp. elegans” in the hand of Linnzus, 
is Cyperus elegans, Linn., i.e. C. viscosus, Aiton, and nor C. elegans 
of Swartz and Kunth. 
The description of Linneus fits C. viscosus, Aiton, exactly, and 
will not fit C. elegans, Kunth. The figure of Sloane cited [t. 75. 
fig. 1] is also C. elegans, Linn. 
We have Cyperus ELEGANS, Linn. (and Rottb.), Goon. 
The Cyperus elegans of Swartz and Kunth will be C. diffusus, 
Vahl. 
Cyperus oporatvs, Sp. Pl. ed. 1, p. 46, n. 10. 
There is one sheet, marked “10. odoratus” in Linneus’s hand,
