= Chamaedorea warscewiczii H. Wendl. in Bonplandia 10: 37. 1862 (Fig. 1C). ≡ Nunnezharia warscewiczii (H. Wendl.) Kuntze, Revis. Gen. Pl. 2: 731. 1891.

Holotypus: [CoSTA RICA or PANAMA]: cultivated in Herenhausen Gardens, Germany, s.d., H. Wendland s.n. (GOET [GOET025403]!; iso-: K [K000462925]!).

Notes. – DAMMER (1905) provided the following description: leaves pinnate, segments 5–7 per side, 2 to 4 times longer than broad, 25–50 cm long, 7–9 nerved.

The lectotype chosen here [GOET025302] consists of a single collection composed of two sheets. One sheet has three inflorescences that lack bracts, and with the remains of some flowers and calyxes. The second sheet contains a section of stem, a large number of detached pinnae, sections of naked rachis and a complete crownshaft. There are two labels in Wendland’s hand: one includes “ Morenia warscewiczii N. 27 & 32. Turialba. 24.3.57 ”, the other “ Ch. homomalla ”.

The remaining syntype [GOET025301] has a label in Wendland’s hand: “27. Ch. homomalla ”.

Chamaedorea warscewiczii (Fig. 1C), which occurs in Costa Rica and Panama, is a handsome species because of its leafy crown and broadly rhombic, sigmoid, conspicuously 5–9-nerved pinnae. The pistillate inflorescence, with its rachillae typically and uniformly curved in the same direction, is distinctive and diagnostic.
