belongs among the glabrous-leaved species of Jussieu’s § Tetrapteris

lan, Department of Zacapa, Guatemala, 11 January, 1905, C. C. Deam, 
no. 232 (type, in hb. Gray). In regard to this species Mr. Deam 
writes: “I recall the place where it grew very vividly. There is a road 
leading from Gualan to the Motagua River, and as is the case with all 
_ travelled ways in Guatemala, it is washed into deep gullies. This plant 
(no. 232) was found in the nude, rocky, dry soil at the side of the road, 
on an angle of about 75°. It grew prostrate in patches extending over 
an area perhaps six feet square. The soil was of a red type, similar to 
that around Chattanooga and Atlanta. I did not see it in any other
