192 THE CACTACEAE. 
This plant was first distributed by the Horticultural Society of London, which obtained 
it from the collector, T. Hartweg, in 1846, from southern Mexico, where it was found 
growing on oak trees. 
Phyllocactus angularis occurs in the index of Labouret’s Monograph (511), credited to 
Lemaire, and also is listed in the Index Kewensis. It may have been a manuscript name 
for this species.

Phyllocactus grandilobus Weber, Bull. Mus. Hist. Nat. Paris 8: 464. 1902. 
Branches bright green, very large, up to 25 cm. broad with the margins deeply lobed and with 
a thick midvein and obtuse or rounded apex; lobes rounded, 3 to 5 cm. long; flowers described as 
large, white, opening at night; fruit red without. 
Type locality: a Hondura, Costa Rica. 
Distribution: Costa Rica. 
Weber speaks of this as a very remarkable species of which he had not seen flowers 
or fruit. His description was based on specimens collected by Wercklé in 1900 and also 
by Pittier in 1905. 
Specimens of the type collection were obtained by Mr. Wm. R. Maxon from A. Brade 
in Costa Rica in 1906 (No. 13), but these have never flowered. In the New York Botanical 
Garden is a small specimen received from Wercklé in 1902 as Epiphyllum grandilobum; 
this shows one very deep lobe; a young joint shows shallow crenations and suggests E. 
macropterum. A plant of this relationship was collected by Mr. Pittier in Panama in 1911 
(No. 4229) and is now growing in Washington, but has not flowered. 
We believe that Phyllocactus macrolobus of Schumann’s Keys belongs here, the specific 
name in error for grandilobus.

This species has long been a favorite with gardeners, and many hybrids with it have 
been produceg+ the flowers, which are delicately fragrant, are diurnal and remain expanded 
for several days. 
Among hybrids with other species are Phyllocactus crenatus amaranthinus, P. elegans, 
erleri, haageanus, lateritius, roseus, splendens, superbus, and vogelit.
