13. Passiflora nigelliflora Hooker (1839: pl. 3635)

≡ Dysosmia nigelliflora (Hooker) M. Roemer (1846: 151) .

≡ Passiflora foetida Linnaeus var. nigelliflora (Hooker) Masters (1871: 631) .

Type: — ARGENTINA. [Santiago del Estero]: “ St. Jago de Estero ” on the Rio Dulce, 1835, J. Tweedie 1171 (holotype K 000323473!). Epitype (here designated):—Illustration from Hooker, Curtis’s Bot. Mag. 12 [Bot. Mag. 65], pl. 3635. 1839.

Notes: —In the protologue of this species, William Hooker (1839) cited a specimen, “ Tweedie Pl. Exsicc. (n. 1170),” presumably at K where J. Tweedie deposited his material and where Hooker worked (Stafleu & Cowan 1986). Such a specimen was found in the collections at K, but it is a type specimen for Passiflora palmatisecta Masters and bears no morphological similarity to that of P. nigelliflora . Another specimen, Tweedie 1171, however, matches perfectly with Hooker’s description and accompanying illustration. The small mistake in numbering was likely a typographical error when published and Tweedie 1171 at K should therefore be accepted as the holotype of this species.

Because the holotype specimen has no flowers, Hooker’s original illustration of the species that was published alongside the protologue (which does includes flowers), plate 3635, is further selected as an epitype to aid in the interpretation of the name.
