Family SCROPHULARIACEAE 
CHEILOPHYLLUM Pennell, gen. nov. 
Stems extensively spreading, repent, much branched, four- 
angled, the angles narrowly winged, and with scattered, minute 
gland-tipped hairs. Leaves opposite, sessile, ovate, cuneate at 
base, slightly dentate, acutish, glandular-dotted, glabrous, the 
margin slightly recurved and thickened, 0.7-0.9 cm. long. Pedicels 
3-5 mm. long, pubescent with gland-tipped hairs, not bracteolate. 
Sepals five, lance-linear, alike. Corolla 3 mm. long, white, cam- 
panulate, the lobes about equaling the tube, the two posterior 
united throughout ; the tube pubescent within on all sides. Fila- 
ments four, glabrous, the posterior pair slightly shorter; anthers 
glabrous. Style glabrous. Stigmas distinct. Capsule 2-2.5 mm. 
long, ovate in outline, acute, glabrous, septicidal and loculicidal ; 
the coalesced placentae thick, persisting, about one-half the length 
of the capsule. Seeds 2-3 mm. long, short-oblong, ridged, mi- 
nutely reticulate, brownish-black. [Name from xeos, margin, 
and ¢vAdoyv, leaf.] 
This monotypic genus is remote from Stemodia, which con- 
sists of erect herbs, with anther-sacs separated on arms of the 
connective and with longitudinally striate seeds. Its uniform 
sepals readily distinguish Cheilophyllum from the group of 
genera usually called Herpestis.

SILVINULA Pennell, gen. nov. 
Stems extensively spreading, repent, much branched, terete, 
strigose pubescent with ascending hairs. Leaves opposite, sessile, 
elliptic-oval, entire, obtuse, slightly pubescent on the margins and 
midrib, glandular-dotted, 0.8-1 cm. long. Pedicels 1-2 mm. long, 
pubescent, at apex with two minute subulate bractlets. Sepals 
five, dissimilar; the three outer oblong-ovate, firm, conspicuously 
ridged, the two inner nearly linear, thin, obscurely veined. Co-
