Tabebuia Palmeri, n. ep. A large tree 18 to 25 feet high : leaves opposite ; leaflets 

 4, 2 to 5 inches long, oblong, obtuse at base, somewhat .acuminate glabrous 

 or nearly so: flowers in close clusters at the ends of the naked branches: calyx 

 small, 2 to 3 lines long, covered with a mealy pubescence: corolla 1^ to 2 inches 

 long with ample tube, mealy-puberulent, white and purplish with yellow spots: 

 capsules terete, 15 inches long, 8 to 10 lines in diameter, straight or nearly so, 

 smooth and ribless: seeds very numerous in several series, oblong, 12 to 18 linos 

 long by 6 lines broad, winged at the ends. — In ravines near the base of the moun- 

 tain. Alamos. March 26 to April 8. No. 320. Called "Amapa," A beautiful 

 flowering tree with its large Panlowuia-like flowers, which Dr. Palmer describes as 

 light-mauve at base, with white and yellow patches; they quickly iade. Only 

 a few flowers were found at the ends of the naked branches. Two leaves, each 

 with 4 leaflets, wore fctund on the tree and Dr. Palmer says the new ones had not 

 begun to appear j there was an abundance of long black pods. The trunk of the 

 tree is covered with a thick, rough bark, resembling the oak j the wood is hard 

 and durable and is generally used for rafters in (he construction of houses in this 

 region. That this is a Tabebuia, as considered by Benth. and Hook., there can 

 be very little doubt, although the inflorescence is a little nmre compact tlian the 

 known species of this genus. It is a little surprising that such a handsome tree 

 of some economic value has until now remained unknown.
