Pelargonium flabellifolium

radical leaves on long, terete, hairy petioles, broadly flabelliform, truncate at base, pilose, palmately many-lobed, and many-nerved, the lobes sharply toothed, the nerves prominent, radiating, with closely netted, prominent veinlets; stipules broadly subulate, acuminate, rigid; scapes very long and hairy; umbel densely many-flowered, with lanceolate bracts; calyx softly pubescent, the segments lanceolate, acute, half as long as the (dark red?) obovate petals. Leaves 5–10 inches long and broad, rigid. The strongly-netted and prominent venation distinguishes this from any of the broad-leaved forms of P. aconitophyllum; the section of the leaf is also different, and the size much greater.
