BiGNONIACEAE 



AsTiANTHUS viMiNALis (HBK.) Bail, Hist. PI. 10:44. 1888. 



Tenacatita Bay, Jalisco, May 8, Elmore 1A14, sandy rocky alluvium 

 along dry stream bank, elevation 10 feet.

 from between Mexcala and Estola, Guerrero. Apparently not previously

Tabebuia pentaphylla (L.) Hemsl., Biol. Cent. Am. Bot. 2: 

 495. 1882. 



Chacagua Bay, Oaxaca, March 21, Elmore D19, a large tree of the 

 forest about 100 feet high with lavender flowers, the ground below 

 covered with its leaves. 



Southern Mexico through Central America to Venezuela and the 

 West Indies. 



As Elmore's notes indicate the leaves are normally dropped in the 

 dry spring season, before or about the time of flowering, the time being

 ployed for ceiling beams and other structural uses. See Standley's ac- 

 count (C.N.H. 23:1320).
