pedicels about 4 mm. long. Sheath 3.5 to 4 cm. long, subcampanulate, densely 
grayish-tomentose outside, smooth inside, bilabiate at tip, the lobes rounded, about 
1.2 cm. long, the anterior one slightly broader than the posterior. Receptacular tube 
about 1.7 cm. long, cylindrical but somewhat broadened at tip; divisions of calyx 4, 
more or less connate at the base, obovate-elliptic, glabrous, all 3 cm. long, but the 
anterior one rounded and emarginate at the tip, 1.3 cm. broad, the 3 remaining ones 
subacute and only 5 to 7 mm. broad. Petals 5 cm. long, spatulate, attenuate at the 
base into a long slender claw, rounded and obtusely subulate at tip, one of them almost 
symmetrical and 1 cm. broad, the 4 remaining ones oblique and narrower. Stamens 
1], connate for about 2 cm. at the base, 10 to 11 cm. long; filaments attenuate and 
subulate at the tip; anthers ovate, about 4 mm. long. Pistil 12 to 12.5 cm. long; 
ovary long-stipitate (stipe about 2.2 cm.), densely tomentose, with about 12 ovules; 
style (about 8.5 cm. long) filiform, arcuate, attenuate, sparsely pubescent at the base, 
glabrous at tip; stigma capitellate, spherical.

The name Brownea macrophylla appears for the first time in 1863, in a garden cata- 
logue, and the nearest approach to a description is an incomplete account by Masters, 
accompanying a poor figure, in the Gardener’s Chronicle for 1873.’ The illustration 
represents a dwarfed specimen growing in the greenhouses of W. H. Crawford, Esq.., 
at Lakeville, near Cork, Ireland. The circumstance that Linden’s plant is said to be 
a native of Antioquia, a State of Colombia, close to Darien, in Panama, where our 
specimens were collected, and certain peculiarities reported in the cited account, 
lead to the conclusion that the tree seen by me in all its tropical exuberance and 
splendor is the same as the one growing in European greenhouses under the above 
name, 
With B. cauliflora Poepp. & Endl., B. macrophylla Linden forms a peculiar section 
of the genus, characterized by having the inflorescences always growing from the old 
wood of the trunk and larger limbs. The former species is a native of the Amazonian 
Peru and differs from the latter by the reduced number of leaflets, the larger number 
of stamens (15 to 20?), and the reduced proportions of its flowers. 
At blooming time, Brownea macrophylla is one of the most striking features of the 
foothill belt in the Sambi Valley. In the semidarkness of the dense tropical forest, 
its erect stems, entirely covered by the red blossoms, and showing for an instant 
between the trunks of the larger trees, strike the eye of the traveller almost as would 
lightning. Among the nativesit is called ‘‘ ariz4,’’ aname which applies also to another 
species growing in Colombia. 
In every investigated case, the trunk of Brownea macrophylla was found to be hollow 
and inhabited by a medium-sized black ant. The blossoms also were almost in- 
variably worm-eaten and full of grubs.

A tree 3 to 10 meters high, the trunk up to 25 cm. thick at the base. Bark grayish, 
rugose on main stem, more or less smooth and verruculose on the limbs. 
Leaves entirely glabrous, with 1 to 3 pairs of opposite leaflets, the terminal ones much 
larger. Rachis 7 to 15 cm. long, thick, the short (about 1 cm. long) petiolar part 
thicker and dark-colored, the petiolules also thick, 5 mm. long. Blades of the basal
