5 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
This species comes nearer the United States species, A. bipinnatus, than any other 
T have seen, but has very different foliage. This seems to be the only representa- 
tive of this genus in Mexico, 
THEACEAE. 
NEW SPECIES OF SAURAUJA. 
Saurauja paucifiora Rose, sp. nov. 
A low shrub; branches, leaves, peduncles, calyx, ete., covered with coarse, stiff,

hairy above and on the midrib and veins below, also somewhat stellate beneath, 1 
to 16 cm. long, 2 to 5 em. broad; peduncles elongated, few-flowered; sepals orbicular, 
the inner ones less setose; corolla white. 
Collected by E. W. Nelson near San Cristobal, Chiapas, altitude 2,100 to 2,640 
meters, September 18, 1895 (no, 3206). 
Saurauja nelsoni Rose, sp. nov. 
Shrub; branches covered with coarse reddish hairs; leaves oblong, rounded at 
base and at apex, scabrous above, soft velvety-stellate bene: ath, 1 to 2 dm. long, 7 to 8 
em. broad, margin wavy, minutely toothed; inflorescence elongated, nearly as long as 
the leaves; sepals orbicular, 6 mm, in diameter, covered with short paleaceous hairs; 
petals orbicular, ‘‘pink,’’ 10 mm. in diameter, 
Collected by FE. W. Nelson, near Totontepec, Oaxaca, altitude 1,122 to 1,670 meters,

rate, roughly pubescent above, densely white-stellate beneath, 7 to 25 em. long, 2 to 
7 em. broad; inflorescence much shorter than the leaves, open; sepals at first some- 
what stellate, but becoming glabrate except the ciliate margin, two of them much 
constricted near the base, all rounded at the apex; petals white. 
Specimens examined: 
Oaxaca: Sierra San Felipe, altitude 2,550 meters, C. G. Pringle June, 1894 (no.

Saurauja reticulata Rose, sp. nov. 
A shrub or small tree; branches scurfy-pubescent, somewhat pilose at the nodes; 
leaves short-petioled, oblong or oblanceolate, rounded at the apex, when mature 
nearly glabrous except for patches of wool in the axils of veins, 1 to 2.5 dm. long, 5 
to 10 cm. broad, finely serrate, the teeth tipped with a deciduous bristle, strongly 
reticulate beneath; peduncles elongated; sepals orbicular, covered with small palea- 
ceous hairs, ciliate on the margin; petals white. 
Collected by C. G. Pringle near Cuernavaca, February 15, 1899 (no. 7862). 
This species is nearest S. serrata, but has different leaves, is pubescent on the sepals, 
grows at a much higher altitude, ete.
