Description

22. Croton lundianus (Didr.) Müller Argoviensis (1866: 662).

Podostachys lundianus Didrichsen (1857: 137).

Type:— BRAZIL. São Paulo: Taubate ́, November 1833, P.W. Lund s.n. (holotype C 10011178!). (Fig. 13, F – I)

This subshrub can be recognized by its pair of stipitate acropetiolar nectary glands, inflorescences with a sterile region between the pistillate and staminate flowers. The lobes of the pistillate calyx are slightly laciniate in most of the analyzed specimens and they are white at anthesis. Croton lundianus is similar to C. glandulosus, but they can be differentiated by vegetative and reproductive characters (see comments in C. glandulosus). The species also resembles C. trinitatis, which has continuous thyrses, and pedicellate pistillate flowers with entire sepals, whereas C. lundianus has discontinuous inflorescences, and subsessile pistillate flowers with slightely laciniate sepals. The species is a member of sect. Geiseleria subsect. Podostachys (Riina et al. 2021).

Distribution and habitat:— It is found in Argentina, Brazil (except Amazonian states), and Paraguay (Riina et al. 2021). Common in open vegetation (‘campo sujo’, ‘campo limpo’), forest edges, disturbed areas, and riverbanks, between 15 and 1055 m elevation. (Fig. 12).

Phenology:— Flowering and fruiting from January to May and September to December.
