14. P. ovatiroiia Gray. Suffrutescent at base, branched, erect, 
3 dm. or less high, the stem and branches, raceme-axes and pedicels 
densely softly pilose with wide-spreading hairs. Leaves ovate (on 
the branches sometimes ovate-oblong), acutish rarely obtuse, with 
often obliquely bent apex, rounded or cuneate at base, with 2- 
pairs of lateral veins, not reticulate, rather densely short-pilose 
both sides with spreading hairs, 1.2-3 cm. long, 0.6—1.3 em. wide, 
on shortly spreading-pilose petioles 2 mm. or less long. Racemes 
rather loose, 2-6.5 em. long. Flowers 7.5-8 mm. long. Sepals 
ovate-lanceolate, acute, 3 mm. long, pilose like the 4-5 mm. long 
oblong to oval abruptly short-pointed soon deciduous wings. Cap- 
sule marginally ciliate, orbicular, 8.5-9 mm. long, 8.5-9 mm. wide.
