DESCRIPTION OF SPECIES. 169 



KHAMNUS I'KUNIFOLIUS Lcsq.' 



PI. XXXY, Pig. 14. 

 Cret. and Tert Fl., p. 85. 



Leave.s small, sulx'oriaceous, ovate-lanceolate, rounded in narrownng to 

 the base, entire, acute or acuuinate (point broken); median nerve thick, 

 straight; secondaries numerous, twelve to fifteen pairs, parallel, campto- 

 drome. 



Of this species I have seen only the fragment figured. It represents a 

 leaf .')""' to G""' long', 2.5"'° broad at the middle, with numerous secondaries 

 diverging at an angle of 50° to 60° at their base, much curved in travers- 

 ing the blade, arched close to the borders, forming a simple series of bows 

 by anastomosing upon each other, and obliquely cut by transverse, close, 

 distinct, mosth- simple, and continuous nervilles, at right angles to the 

 midril). 



The leaf is comparable to Salix urrrilloso Heer," especiallv for the 

 direction of the close, simple nervilles. But this last leaf has the second- 

 aries comparatively more distant, somewhat branched, especially at a more 

 acute angle of divergence, and the leaf, which is more narrowly lanceolate, 

 is narrowly cuneiform to the base. By the same character it has a degree 

 of likeness to that of FicMS psidiopsls Massal.,^ differing from it in the lea\-es 

 not being subcordate but attenuated at the base and the secondaries without 

 branches.

Ehamxus Mtjdgei, sp. nov. 

 PI. XXXVII, Figs. 2,3. 



Leaves coriaceous, oval, rounded and pointed to the apiculate apex, 

 narrowing to a short, thick petiole by an outward curve : secondaries numer- 

 ous, parallel, a little curved in passing to the borders, camptodrome. 



Two leaves varying in length from 4.5"'" to 7'"', and from 2*"" to S'"' 

 broad at the middle, with entire borders; primary nerve stout, enlarged at 



' No. 709 of tbe collection of Mr. E. D. Lacoe was referred to this species by Prof. Lesqnereux with 

 the fiiUowiug remarks: " Ithamnus prniiifoluis Lesq., No. 709 of L icoe's collection, is ;i leaf of this 

 species. It is a little larger, more narrowed to tbe base ; tbe secouilaries at a slightly more acute anijle 

 of divergence, some of themflexnons, turning downward at base in joining the midrib. The nervillefi 

 are of a normal position, at right angles to the midrib." — F. H. K.
