mining towns of that company, a few miles east of Santiago, 
where we were received and hospitably entertained by Mr. G. 
W. Pfeiffer, superintendent. The railroads of these mines 
enabled us to traverse a considerable stretch of country, both 
on the coast and at a short distance from it, and a trip on horses 
into the hills supplied an additional view of the flora. One of 
our principal objects in visiting this place was to see the cactus 
of the genus Leptocereus collected near Berraco some years ago 
by Mr. William R. Maxon, of the United States National 
Museum, and one of the railroads took us directly to it under 
the guidance of Mr. McGill, of Mr. Pfeiffer’s staff. This 
genus Leptocereus has been of great interest on account of recent 
discoveries of undescribed species in Cuba. Three years ago, 
when the paper by Dr. Rose and myself on ‘‘'The Genus Cereus 
Leptocereus arboreus, which inhabits rocky soil on the west side 
of Cienfuegos Bay, and Leptocereus Leoni, discovered by Brother 
Léon, of the Colegio de la Salle, Vedado, Havana, on limestone 
cliffs in the Sierra de Anafe near Guayabal. Our examination 
of the plant at Berraco proves definitely that it represents a 
fourth still undescribed species, of which we secured cuttings 
for cultivation, and, by great good fortune, two fully opened 
flowers; these are white, and of relatively small size, the very 
numerous petals spread out flat, appearing at first glance like 
the flower heads of some single chrysanthemum, and wholly 
different from any cactus flower hitherto known to us. 
The arborescent cactuses of the region were studied under 
favorable conditions on the coast just east of the Daiquiri land- 
ing, where they are abundant, and cuttings of them were taken 
for cultivation. Here also we studied with great interest a 
fine, flowering tree of the Cuban Catalpa; it has narrow leaves 
and much smaller flowers than any of the northern trees of that
