III. Blanchetia Candolle (1836: 75) . Type:— Blanchetia heterotricha DC.

Irwinia Barroso (1980: 11) . Type:— Irwinia coronata Barroso (= Blanchetia coronata Loeuille & Pirani in Loeuille et al. 2014: 1).

( Fig. 11 A–B , 12 A ).

Shrubs, sometimes subscandent, stems branched. Indumentum pubescent, composed of dark multicellular unbranched trichomes, pale stellate trichomes with forked arms, sometimes porrect or geminate. Leaves alternate, shortly petiolate, sheathless, blade papiraceous to subcoriaceous, discolorous, margin serrate to dentate, flat (not revolute), venation eucamptodromous. Inflorescence a terminal, pedunculate panicle of capitula with short internodes. Capitulum shortly pedunculate. Involucre ovoid; phyllaries 3–4-seriate, strongly imbricate, persistent, pubescent; receptacle sometimes with thin partitions. Florets 5–10; corolla creamy, tube longer than limb; corolla lobes apices glabrous; anthers calcarate; style lacking basal node. Cypsela prismatic, glabrous; carpopodium inconspicuous; pappus uni- or biseriate, caducous (except outer series in B. coronata ), paleaceous, whitish. Chromosome number: n = 23 ( B. heterotricha ).

Taxonomic notes: —A genus of two species from the Caatinga domain in northeastern Brazil. The many features shared by these species (type of trichomes, involucre, etc.) clearly indicate a close relationship between them, so their placement in two monotypic genera ( Blanchetia and Irwinia ) is not accepted here (see Loeuille et al. 2014).
