    Leaves spirally arranged, sessile, (2.5 –) 3.5 – 9 (– 12) × (0.8 –) 1 – 2.5 (– 3.5) cm, chartaceous, oblanceolate to lanceolate, base attenuate, apex acute, margins minutely dentate, venation reticulodromus, abaxially woolly with prominent midrib, adaxially hirsute
    Inflorescence terminal, with corymb-like branches, bracteolate, bracteoles 0.6 – 1.6 (– 2) × 0.3 – 0.7 (– 0.9) cm, oblong to lanceolate, base obtuse, apex acute, margin entire, both surfaces hirsute, hairs densely grouped on midrib and margins
    Capitula pedicellate, pedicels (0.7 –) 1.5 – 6 cm long, woolly; involucre hemispherical, biseriate, external phyllaries c. 8, leafy, 7 – 8 × 2 – 3 mm, oblong, hirsute, internal phyllaries c. 23, rigid, c. 10 × 2 mm, lanceolate; receptacle epaleaceous, dense pubescent
    Cypselas c. 6 mm long, cylindrical, base truncate, with 8 longitudinal ribs, hirsute, glandular; pappus 1-seriate, 8 – 9 mm long, barbellate, pale yellow, persistent.
    Only recorded from Serra do Ibitipoca in southern Minas Gerais state, Brazil.
    Campos rupestres, among rocks and herbaceous vegetation with sparse shrubs and small trees.
    Data on distribution and abundance of Trixis forzzae are restricted to the type locality. Consequently, the endemicity of this species is recognised such as that observed before in the Park for species of Bromeliaceae, Velloziaceae, Poaceae, Melastomataceae and Gesneriaceae. Thus it seems prudent to treat it as Vulnerable (VU) D1 + D2, following the IUCN (2001) categories and criteria.
    This species is named for Rafaela CampostriniForzza, curator of RB, Coordinator of the Flora do Parque Estadual do Ibitipoca and our personal friend. Trixis forzzae is closely related to T. glaziovii Baker, but clearly differs by the presence of dense woolly indument; wingless stems; leaves not rosulate, chartaceous, with the base attenuated; corymb-like inflorescence. Furthermore, both species occur in distinct habitats: Trixis forzzae is only known from the camposrupestres (Giulietti & Pirani 1988) of Serra do Ibitipoca, and T. glaziovii from the campos de altitude (Safford 1999) of southern and south-eastern Brazil. Among the Brazilian species, Trixis glaziovii and T. lessingii DC. are considered herbaceous, with rosulate leaves and a fistulose stem (Katinas1996). However, T. forzzae is a subshrub, characterised by the lack of rosulate leaves and by the woody and branched stem. Among the shrubby species, only T. forzzae and T. verbascifolia (Gardner) S. F. Blake have folicaceous external phyllaries. Nevertheless, the latter can be distinguished by its radiate capitula and 3 – 4-seriate phyllaries.
