2.1 Aporocactus flagelliformis (Linnaeus) Lemaire (1860: 68) ≡ Cactus flagelliformis Linnaeus (1753: 467) ≡ Cereus flagelliformis (Linnaeus) Miller (1768: unpaged) ≡ Disocactus flagelliformis (Linnaeus) Barthlott (1991: 87) .

Lectotype (designated by Bauer 2003a: 12):—[illustration] in Plukenet (1692: t. 158, f. 6).

Epitype (designated by Bauer 2003a: 12):— MEXICO. Hidalgo: Along Mex 85, north of Parque Natural de los M[ar]moles, north of Cuesta Colorada, Lautner L00/241 (ZSS-22701!).

= Aporocactus flagriformis (Zuccarini ex Pfeiffer) Lemaire (1868: 58) ≡ Cereus flagriformis Zuccarini ex Pfeiffer (1837: 111) .

Type:—Not designated.

= Aporocactus leptophis (A.P. de Candolle) Britton & Rose (1909: 435) ≡ Cereus leptophis A.P. de Candolle (1828: 117)

Type:—Not designated.

Notes: ―Both Cereus flagriformis and C. leptophis are not typified. The description of C. flagriformis was based on material introduced by Karwinsky collected near San José de l’Oro, Oaxaca, Mexico. Bravo (1978) assumed that A. flagriformis might be merely a form of A. flagelliformis . Hunt (1989) mentions a plate of Pfeiffer & Otto (1839, t. 12) that could serve as iconotype, but the plant pictured has no significant differences to A. flagelliformis .

No type specimen or other verifiable material of C. leptophis appears to exist. De Candolle (1828) mentions a collection of Thomas Coulter No. 32 in the protologue, but does not cite any herbarium vouchers. He reports to have received a collection of living plants from Mexico from Coulter; the number 32 and other numbers mentioned in the same work refer to that collection. It is not clear whether herbarium specimens exist, they could not be located so far—if such a specimen could be located, it would be the type.

Both names require further investigations from the nomenclatural point of view.

Oaxaca: San Juan del Estado, 1500 m, Lau 1331 (ZSS-22702!).
