Description Glabrous shrublet 3-55 cm tall with a taproot, usually bushy with the branches erect, strict or the lower ones ascending, rarely decumbent and matforming, not rooting at the base; stems 4-lined at first, eventually terete, sparsely gland dotted with the internodes shorter than the leaves. Leaves sessile, erect or suberect, usually imbricate, coriaceous, subconcolorous; lamina (3-)8-14(-18) mm long, 0.8-3.5 (-5.0) mm wide, linear, elliptic-oblong, lanceolate or rarely ovate- lanceolate, the apex acute, the margin entire, revolute, the base parallel to nar- rowly cuneate, the lateral vein pairs 0-3, without reticulate venation, the laminar glands pellucid, punctiform, dense', large, more prominent beneath, the marginal glands absent, the upper epidermal cells bullate. Inflorescences 1-25-flowered, monochasial after the first or second grade, with foliate and bracteate' branches mixed, or wholly foliate, without subsidiary inflorescence branches; pedicels 4-10 mm long in fruit; bracts and bracteoles mostly foliaceous when present. Flowers 0.6-1.0 cm (or larger?) in diameter; sepals 4-8 mm long, 1.0-2.3 mm wide, unequal, oblanceolate-spatulate, oblong, elliptic to linear, acute, 5-nerved, the nerves prominent; petals bright yellow to orange, 5.0-8.5 mm long, 3-6 mm wido, slightly exceeding the sepals, obovate to oblong; stamens 20-40, not fascicled, the longest 3.5-6.0 mm long, 3/4 times as long as the petals, the anther gland amber; ovary 1.5-1.8 mm long, 0.6-1.0 mm wide, narrowly ovoid-ellipsoid, the styles 3, 2-3(-4) mm long, 1.3-1.5 times as long as the ovary, the stigmas broadly capitate, the' placentas 3, parietal with numerous ovules. Fruits 3.5-5.0 mm long, 2-3 mm wide, narrowly ovoid to cylindric, trigonous, acute to subacuminate, shorter than the sepals; seeds ca. 0.6 mm long, cylindric, longitudinally ribbed with transverse striae.
Habit shrublet
Distribution occurs from Panama northward to Mexico (Mexico and Guerrero), its nearest ancestral species being apparently H. chamaemyrtus Tr. & P1. of Colombia. In Panama, it is found at higher altitudes in the Chiriqui mountains (1,100-3,475 m) and there is one record from Cocle Province (1,000 m) .
Elevation 1,100-3,475 m
Note It occurs in savannas and grasslands, especially on old lava flows. At exposed sites on the highest part of its range (2,500-3,475 m) it adopts a decumbent matlike form (H. woodsonii), but this is only an extreme variant, not a distinct taxon.
