Type in the U. S. National Herbarium, no. 531119, collected in a garden at 
Cali, Cauca, Colombia, flowers and fruits,. January 1, 1906, by H. Pittier 
(no. 925). 
By the tomentose ovary this is brought near J. lasiogyne Bur. & Schum., but it 
differs in the villous leaflets, the narrower rachis of the pinns, and the shape 
and size of the fruit. It has also the inflated base of the corolla found in that 
species and in J. filictfolia, with which latter it can not be confused. 
Jacaranda caucana is a favorite with the natives of the Cauca Valley, on 
account of its beautiful blue flowers. They call it “gualandai.” The speci- 
mens in the U. 8S. National Herbarium were collected in a garden, but the tree 
was said to grow wild in the district surrounding Calf. In the Flora de 
Colombia, by S. Cortés, we find mentioned on page 99 a Jacaranda gualanday, 
from Cundinamarca, given as synonym of J. mimosifolia D. Don. There is, 
however, nothing to indicate that the species is the same as the one from Calf, 
since no description is given. Furthermore, J. mimosifolia is but another name 
for J. acutifolia, which is quite distinct from J. caucana. If then J. gualanday 
Cortés, a hypofiym, is really a synonym of J. mimosifolia, it has no standing, 
and besides it would not apply to the Cauca tree. 
Jacaranda caucana probably blossoms twice in the year. At the time of my 
visit in the Cauca Valley there was only a scanty flowering, and it was said 
that the time to see the trees in their full glory was about July or August. 
In July they drop their leaves, and the flowers immediately follow.
