Revision of the genus Ochagavia

Authors:G. Zizka, G.K. Trumpler, amp & O. Zöllner

Publication:Willdenowia 32:331-350. (2002)

Abstract:—The genus Ochagavia is revised. Four species, O. andina, O. carnea, O. elegans and O. litoralis, are recognized, all are endemic to Chile. A key to the species, descriptions, illustrations, full synonymies and data on the distribution and ecology are given. The new combinations O. litoralis and O. andina are validated, and several names are typified. Relationships of the genus within the subfamily Brome- lioideae are discussed.

Published names (2):
Ochagavia andina
Ochagavia litoralis

Taxonomy:Fascicularia litoralis The combination Fascicularia litoralis by Mez in Martius (Fl. Bras. 3,3: 627. 1894) is not validly published because the basionym was cited without author. (p.342). —Hechtia pitcairniifolia The illustration in the protologue of Hechtia pitcairniifolia (= Fascicularia pitcairniifolia), designated as the lectotype of that name by Smith & Downs ( 1979), makes clear that the species belongs to the genus Ochagavia. Both the dimension of the leaves given in the protologue and the lectotype indicate that F. pitcairniifolia is with some certainty conspecific with 0. litoralis. (p.32: 340-343). —Ochagavia andina Epitype designated: Baños Cauquenes, 1873, Reed (CONC 93288) (p.343-344). —Ochagavia chamissonis Treated as a synonym of Ochagavia carnea (Beer) L.B. Smith & Looser. —Ochagavia leiboldiana The type specimen deposited in the collections of the Natural History Museum in Vienna (W) was destroyed in a fire shortly after World War II (Till 1994). No collecting data (coastal or Andean habitat) are given in the protologue, thus it remains doubtful from the de scription, whether Rhodostachys leiboldiana must be regarded conspecific with Ochagavia litoralis or O. andina. For this reason, we did not select a neotype. The information given about leaf size (length: ± 0.4 m, width: up to 8 mm) and indumentum of the abaxial leaf blade surface clearly points toward one of the above mentioned Ochagavia species (p.347). —Ochagavia lindleyana Per Zizka et al. the publication of the name Ochagavia lindleyana Mez fulfilled all requirements for a valid publication of a new name, the name is regarded as published by Mez, not as a new combination. Lectotype designated: Chile, Colchagua, Gay 155 (P!). Treated as a synonym of Ochagavia litoralis. (p.340). —Placseptalia rebecae Considered a synonym of Ochagavia litoralis. Lectotype designated: Chile, region V, Valparaiso, Laguna Verde, 3.1947, M. Espinosa (SGO 084893!). –Paralectotype: Chile, Curauma, 6.3.1947, M. Espinosa (SGO 070803; FR [photo]). (p.340). —Rhodostachys chamissonis Treated as a synonym of Ochagavia carnea (Beer) L.B. Smith & Looser. —Rhodostachys leiboldiana Rhodostachys leiboldiana Mez in Candolle, Monogr. Phan. 9: 338. 1896 [“leiboldianus”]. Holotype: Chile, without locality (“in Exp. Donau”), Leibold 2960 (W, destroyed) &#8801; Ochagavia leiboldiana (Mez) L. B. Sm. & Looser in Rev. Univ. (Santiago) 18(8): 1078. 1934. Remarks. – The type specimen deposited in the collections of the Natural History Museum in Vienna (W) was destroyed in a fire shortly after World War II (Till 1994). No collecting data (coastal or Andean habitat) are given in the protologue, thus it remains doubtful from the description, whether Rhodostachys leiboldiana must be regarded conspecific with Ochagavia litoralis or Ochagavia andina. For this reason, we did not select a neotype. The information given about leaf size (length: ± 0.4 m, width: up to 8 mm) and indumentum of the abaxial leaf blade surface clearly points toward one of the above mentioned Ochagavia species.".
