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 x tAos, margin, 

 and cf>v\\ov, 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 Chcilophyllum 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-
