Type
Martinella martini (DC.) Baill. [= Martinella obovata (Kunth) Bureau & K.Schum.].
Description
Lianas. Roots with swollen portions. Branches green or light brown, terete, tetragonal, glabrous, puberulous or pubescent, eglandular trichomes simple, glandular trichomes stipitate or patelliform, with a continuous ridge at the interpetiolar region, with few interpetiolar patelliform trichomes; prophylls of the axillary buds minute, glabrous, puberulous or pubescent. Leaves 2-foliolate with the terminal leaflet generally modified in a trifid tendril; leaflets membranous, chartaceous or coriaceous, glabrous to pubescent, margins entire, revolute, more conspicuously when dried, with or without mite-domatia, with patelliform glands on the adaxial surface. Inflorescences axillary, botryoid, racemose, or a thyrse. Flowers with calyces tubular-campanulate, irregularly 2–4(–5)-lobed, lobe apices mucronate or aristate, chartaceous, with scattered patelliform glands; corolla deep purple, lilac, dark magenta or yellow, narrowly tubular at basal portion and wide campanulate at upper portion, straight to slightly curved, membranous, outer surface glabrous, inner surface glabrous with eglandular trichomes concentrated at stamen insertion; stamens included, glabrous, pollen tricolpate and reticulate; ovary terete, smooth, glabrous, with a single series of ovules per placenta, style glabrous, stigma rhombic, glabrous. Capsules drying brown, linear, flattened, smooth, glabrous, with calyx normally persistent; seeds oblong, winged, with wings opaque, green or beige.
Discussion
The nomenclatural type of Martinella has been indicated as Martinella martinii (DC.) Baill. ex K.Schum. in earlier treatments of the genus (e.g., Lohmann and Taylor 2014[1]; Zuntini and Lohmann 2014[2]) because Schumann (1894)[3] was the first to explicitly associate the genus name with a species epithet. However, Baillon (1888)[4] provided a footnote that says “Generis typus est Bignonia Martini DC.,” representing a valid reference to a previously published basionym, and validly publishing the name Martinella martini (DC.) Baill. (see Art. 41.3 and 38.13 of Turland et al. 2018[5]).
As circumscribed here, Martinella comprises five species distributed from southern Mexico to eastern Brazil. A key to all species recognized is given below:
