Description

33. Drosera × fontinalis Rivadavia (2009: 121) (D. grantsaui × D. tomentosa). Figure 23a, b

Type: — BRAZIL Minas Gerais: Grão Mogol, 09 September 1994, Rivadavia 302 (holotype SPF-93213!).

Perennial, rosetted, acaulescent. Leaves semi-erect, with circinate vernation, oblong; stipule rectangular, apical 1/2– 1/3 fimbriate. Scape erect at the base; base glabrous to sparsely eglandular-pilose; apex, pedicels and sepals glandularpilose. Seeds usually aborted, but if present, then obconical, testa reticulate.

Illustrations: —Rivadavia (2009: 122, fig. 1—habit and details).

Distribution: — Brazil (Northeast: BA; Central-West: GO; Southeast: MG), endemic. Always found syntopically with one or both parental species. Common, though not always present, wherever the two parental species are syntopic (Fig. 23a).

Habitat: —Grows in waterlogged habitats on stream sides and seepages in campo rupestre vegetation, in sandy to peat-sandy soils.

Phenology: —Observed in flower from June to November, usually coinciding with the flowering period of D. tomentosa.

Notes: —The hybrid D. × fontinalis can result from the cross of D. grantsaui with either of the two D. tomentosa morphotypes.

Specimens examined: —For an extensive list, see Rivadavia (2009: 123).
