Summary  
The neotypification of Opuntia australis F.A.C.Weber, basionym of Pterocactus  
australis (F.A.C.Weber) Backeb., is made here thanks to the discovery of Weber’s  
personal notes about it, and of two notebooks containing respectively a drawing  
and a short description of that plant, both made at the time of its first collection in

first discovery and the cultivation of an early plant by F.E. Schlumberger on Weber’s  
behalf. A Weber’s note confirms he knew the mentioned illustration. A herbarium  
specimen from the same gathering has been found, but it cannot be considered  
original material since there is no evidence that it was seen by Weber. However, this  
specimen is here designated as epitype.

Se realiza la neotipificación de Opuntia australis F.A.C.Weber (basónimo de  
Pterocactus australis (F.A.C.Weber) Backeb.), gracias al hallazgo de manuscritos  
sobre esta especie de su autor y de una libreta con un dibujo a color del  
taxón, efectuado al tiempo de su primera colección. También se menciona una  
segunda libreta, complementaria, con una breve descripción de la planta y la  
expedición científica -poco documentada- que realizó el hallazgo en 1882, y a F.  
E. Schlumberger, quien la cultivó, colaborando con el autor. Una nota de Weber  
confirma que conoció la ilustración mencionada. Además, se encontró un ejemplar  
de herbario de la misma colección, que si bien no puede ser considerado material  
original ya que no consta que haya sido visto por el autor, es designado como  
epitipo.

IntroductIon  
Opuntia australis was described by the French military medical doctor and  
amateur botanist Frédéric Albert Constantin Weber (1830-1903), who devoted  
his botanical research efforts basically to the Cactaceae family. He collaborated  
actively with the “Muséum National d’Histoire Naturelle, Phanérogamie”,  
Paris, and contributed to the famous Dictionnaire d’Horticulture by Désiré Bois,  
published 1893-99.  
In charge of the cactus family in Bois’s Dictionnaire, Weber published the  
original description of Opuntia australis F.A.C.Weber in 1898. Although the  
description is short, it accurately describes the plant with diagnostic characters,

Weber’s note C above (Fig. 1) refers to the  
documents illustrated in Figures 2 and 3, found at  
the botany library of MNHN under reference Per  
K 42. The two drawings are parts of a sketchbook  
(Heimsch, 1882) with 77 colored drawings of plants.  
The text on the cover page indicates that they were

drawn by the 2 chief mechanic Heimsch of the  
ship “Le Volage” (Fig. 2), under the supervision  
of the ship’s medical doctor, Dr Couteaud, who  
collected the plants, and of the captain, M. Ingouf.  
The drawings are all numbered and the scale  
is sometimes mentioned by a meticulous hand,  
probably Heimsch’s, while some plates also bear  
names of plants, written with a pencil, often with  
question marks, by another anonymous hand. No  
date is provided in this sketchbook.
