40 Contributions from the Gray Herbarium 
habit. Hoffmann, however, in the Pflanzenfamilien (iv. pt. 5, 235 
(1890)) has reduced Pascalia Ort., with its later synonym Lorent- 
zia Griseb., to Wedelia under the section Cyathophora DC., which 
seems much the better disposition of the plant. Its habital pe- 
culiarities, slight at the best, as well as the suggested difference in 
ligules, are quite negligible if the variation among the species of 
Wedelia itself, as of any large helianthoid genus, is taken into 
consideration, while they are equally shown in W. crassiuscula 
above described, whose pappus is quite that of Wedelia. But 
Pascalia itself does not show pappus characters of any real diag- 
nostic significance when compared with many undoubted Wedelias. 
In many species, certainly, the pappus consists of a strongly thick- 
ened cup; but in others, for instance W. filipes Hemsl. and some 
members of the section Wollastonia (DC.) O. Hoffm.,-the coales- 
cence of the squamellae is not more pronounced than in Pascalia. 
The pappus of Wedelia glauca (Pascalia glauca Ort.), of short Ir 
regular squamellae united below on young achenes, becomes 
age a low jagged cyathiform corona, or is sometimes split nearly 
to the base or in extreme maturity entirely lost. 
Lorentzia pascalioides Grisebach, as represented at Kew by sup- 
posedly authentic material sent by Grisebach himself, is a mixture 
of Wedelia glauca and a Viguiera near V. anchusaefolia (DC.). 
Baker. On a loose leaf with the latter specimen Mr. Baker has the 
following note: “ Grisebach has sent us two totally different 
plants under the name of Lorentzia pascalioides, viz., this and the 
true Pascalia glauca and it seems to me his description in Plant. — 
Lorentz. p. 135 has been drawn up partly from one and partly 
from the other. JGB.” It seemed to the writer, however, when 
studying the same specimens at the Kew Herbarium, that the 
description above cited referred wholly or almost wholly to the 
Pascalia, and had very little application to the Viguiera. 
Stemodontia (Wedelia) elongata Rusby! Mem. Torr. Club iii. pt: 
3, 58 (1893). — Rusby’s Stemodontia elongata (not Wedelia elon- 
gata (Boj.) Vatke, Abh. Nat. Ver. Bremen ix. 121 (1885)), based 
on Bangs’ number 685 from Yungas, Bolivia, is identical with the 
widely distributed Hextropsis BUPHTHALMOIDES (Jacq.) Dunal of 
Central and South America. I find that this identification was 
likewise recorded by Dr. J. M. Greenman on the sheet in the Gray 
Herbarium some years ago.
