Note 410 — I.—PHÆNOGAMOUS OR FLOWERING PLANTS. (continued 3)
Reading edition
That of Guaiacum arboreum DC. is apparently very different. This tree, occurring in New Granada, has already been noticed (1571-1577) by Francisco Hernandez (Nova plantarum, animal, et mineral. mexicanor. hist., Romæ 1651, fol. 63) under the name of Guayacan. He mentions its large umbels with yellow flowers, those of Guaiacum officinale, the “Hoaxacan” or Lignum sanctum, being blue. In the Prodromus Floræ Neo-Granatentis (Ann. Scienc. nat. xv., 1872. p. 361) J. E. Planchon also describes Guaiacum arboreum, known there as Guayacan polvillo; its wood is of an almost pulverulent fracture.
