28783— Continued. 



the new genus the specific name was changed and the species has since usually been 

 known as Argania sidewxylum Room, and Schult. Tlie original specific name is here 

 restored in accordance with the now nearly universal custom. 



The name Sideroxylon spinosum as used by Linnaeus in the Species Plantarum appears 

 to have included two distinct plants, the one under consideration here and that usually 

 recognized as the type, being the one represented by the Plukonet synonym, but not 

 the Malabar plant referred to by the Rheede citation. The species seems to have 

 been originally described by Linnseus in his Hortus Cliffortianus from a garden plant, 

 and he is in error in ascribing India as its habitat. The species is known in an indig- 

 enous state only in Morocco.

28785. PiRATiNERA uTiLis (II. B. K.) W. F. Wight. Palo-de-vaca. 



The "cow tree of South America" was first named Galactodendrum utile by Hum- 

 boldt, Bonpland, and Kunth (Nova Genera et Species, vol. 7, p. 163) in 1825. In 

 1830 David Don (Sweet, Hortus Britannicus, ed. 2, p. 462) placed the species in the 

 genus Brosimum, giving it the name B. galactodendron, which in 1880 was corrected 

 by Karsten (Deutsche Flora, p. 498) to Brosimum utile. The generic name Brosimum 

 was published by Swartz (Nova Genera et Species Plantarum, p. 12) in 1788, with 

 two species, B. alicastrum and B. spurium. In 1775, however, Aublet (Plantesde 

 la Guiane Franyoise, vol. 2, p. 888, pi. 340, fig. 1) published the genus Piratinera with 

 one species, P. guianensis, which is considered to be congeneric with Brosimum ali- 

 castrum Swartz. The change of name from Brosimum galactodendron to Piratinera 

 utilis was made by Mr. W. F. Wight in the Century Dictionary and Cyclopedia (vol 

 12, p. 934, 1909) under "palo," subhead "palo-de-vaca."
