HIBISCUS. with obcordate tonentose leaves, and pink flowers; both these last were very handsome shrubs.
The _first glume_ is cuneately obovate or obcordate, yellowish with red brown tips or dark brown with yellow tips, chartaceous below, membranous, hyaline and ciliate at the truncate, emarginate or retuse apex, 7 - to 9-nerved, the nerves abruptly ceasing towards the apex.
The first glume is large, broadly obovate or obcordate, cuneate, villous with brown hairs, 7 - to 9-nerved.
The remaining glumes _fourth_ to _seventh_ are borne by the rachilla, thinly chartaceous, broadly obcordate or obovate, gradually diminishing in size, purple-tinged, 3 - to 5-nerved, scaberulous.
Each petal has its tip inflexed, giving it an obcordate appearance.
The _laevifolia_ petals become smaller and are often not emarginated at the apex, becoming ovate  instead of obcordate.
The petals are as a rule obcordate, but this type may be combined with others having more or less broad emarginations at the summit, and with differences in breadth which vary from almost linear types to others which touch along their margins.
= -- Fruiting catkins erect or spreading, cylindrical, about 1-1/4 inches long and 1/2 inch in diameter, stalked; scales 3-parted above the center, side lobes larger, at right angles or reflexed: nuts small, ovate to obovate, narrower than the wings, combined wings from broadly obcordate to butterfly-shape, wider than long.
A vertically ovate leaf is the fame with an ob - verfely-ovate or obovate leaf; and a vertically cordate leaf is the fame with an obverfely cor - date or obcordate leaf. —
