Original diagnosis/description

Inflorescence axis with two different types of scars. Lateral inflorescence units broadly obovate in outline, sometimes with angular margins. Lobes of lateral units more or less obtriangular in outline. Scales of lateral units membranous without perforations. Each lateral unit with five sessile flowers. Outer tepals short, broadly triangular; inner tepals longer, narrowly obovate to spathulate with an indistinct keel. Receptacle concave, forming a narrow floral tube. Staminal appendages flat and differentiated into stalk and triangular head. Staminodes short, narrow, cuspidate, and dorsiventrally flattened. Resin bodies globular, occurring in tissue of lateral inflorescence units and carpels. Indumentum dense, occurring on all surfaces except staminodes and staminal appendages. Subsidiary cells of stomata often divided several times.


Hirsute (Latin): covered with fairly coarse and stiff long erect or ascending straight hairs (Stearn 1998).
