Felipe, Retalhuleu, 13 Jan. 1917, Holway 703 (Type in Gray 
Herb.). — Perhaps nearest to L. discolor (H. & A.) Hemsl., which 
has leaves whitened beneath and a different involucre. The very 
imperfectly known L. Liebmannii Klatt, represented in the Gray — 
Herbarium by a fragment of the inflorescence from the type, seems 
also to be nearly allied. 
Gynoxys boliviana (Klatt) Blake, comb. nov. — Liabum bolivi- 
anum Klatt ! Ann. Naturh. Hofmus. Wien ix. 362 (1894). — 
Fragments of the type of Liabum bolivianum Klatt, collected by 
Cuming in Bolivia, are now in the Gray Herbarium, accompanied 
by a good sketch, and show the plant to have the 1-seriate involucre. 
and distinctive style-tips of Gynorys. The species is close to G. 
psilophylla Klatt, but apparently distinct in involucral characters.
