Deprea orinocensis (Kunth) Rafinesque (1838: 57) .

Physalis orinocensis Kunth in Humboldt et al. (1818: 12).

Larnax suffruticosa (Dammer) Hunziker (1977: 8) . Iochroma suffruticosum Dammer (1905: 386) synon. nov.

Lectotype (designated here):—[ ECUADOR] Crescit in sylvis Montis Corozá , S.[odiro] n. 114/62—fl. et fr. Oct. 1891 ( QPLS! , isolectotype: F 619431 ! ).

Notes: —Dammer described I. suffruticosum Dammer (1905: 386) based on a Sodiro specimen deposited at B but this holotype was destroyed. The original specimens of Sodiro are thought to be deposited at QPLS and Q, both in Ecuador ( Stafleu & Cowan 1985). No type specimen of I. suffruticosum was found in other herbaria (K, Q, B, BAF, NY, P, G, GH, MO, QCNE, QCA, USM, US) where Sodiro´s collections also exist. Fortunately, we found an isotype in QPLS and a small fragment accompanying the photograph at F (619431, barcode V0093670F).

Sodiro collected the type specimen at Montis Corozá (= Monte Corazón , Ecuador), which is a highland area situated between Cotopaxi and Pichincha Provinces. The specimen at QPLS consists of a well preserved branch with two flowers and various fruits. For this reason we have chosen it as the lectotype ( Fig. 19 F ). The JSTOR database (http://plants.jstor.org/specimen/ny00348284) has erroneously loaded the specimen Jaramillo et al. 8766 as isolectotype for I. suffruticosum based on a typed label from the unpublished Sawyer Ph.D. dissertation (1999). Jaramillo´s specimen belongs to Larnax toledoana Barboza & S. Leiva described in this article (see above).

Hunziker (1977) transferred I. suffruticosum to the genus Larnax and this name has remained in the literature until now. After a detailed analysis of the lectotype, the corolla shape and the ratio of corolla lobes to tube length demonstrate that it belongs to Deprea . The presence of branched hairs on the leaves and corolla, the ratio of corolla lobes to tube length (0.78:1), the length of pedicels shorter than 12 mm, and the conspicuous ribs in the accrescent calyx loosely enveloping the berry unequivocally match with Deprea orinocensis .
