 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-

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. Pittieri is densely pubescent with 

 short somewhat hirtellous pubescence. 



Zaluzania Pringlei. Shrub: stems covered with a grayish bark; 

 ultimate branches striate, appressed-puberulent, purplish : leaves alter- 

 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 :
