Gymnolomia Pittieri. Stem somewhat striate, reddish-brown ; 
the younger branches densely short-hirtellous-pubescent, with few scat- 
tered hirsutish hairs intermixed: leaves ovate-lanceolate, 4 to 8 cm. long, 
1 to 4 cm. broad, acuminate, acute, crenate-serrate, narrowed below 
into a subpetiolate base, hirsute-hispid above, paler and densely pubes-

trays, 5 to 6 cm. in diameter, terminating the stem and branches on

This species has hitherto been confused with Gymnolomia platylepis, 
Gray, from which, however, it is well distinguished by the smaller leaves 
and heads, and by the character of the pubescence. The stem and 
branches of G. platylepis are usually pubescent with long spreading 
pilose or pilose-hirsute hairs, while G. Pittiert is densely pubescent with 
short somewhat hirtellous pubescence. E 
Zaluzania Pringlei. Shrub: stems covered with a grayish bark;

nate, petiolate, ovate, 3.5 to 5 cm. long, 2 to 3.5 cm. broad, short- 
acuminate, obtusish or submucronate-acute, subentire to somewhat 
crenate-denate, cuneate to subcordate at the base, slightly hispidulous 
above, puberulent beneath especially on the midrib and nerves ; petioles 
slender, canaliculate, appressed-puberulent, 1 to 1.5 cm. In length: 
inflorescence a terminal round-topped paniculately corymbose cyme:
