CEANOTHUS FIBEILLOSUS, Sjp. nov. 



Leaves snbcoriaceous, ovoid, obtuse, rounded to the base, (petioled ?) 

 five-nerved from the top of the petiole ; nervilles in right angle to the 

 medial vein, continuous. 



Species related to Ceanothus ovoideus, Gopp., (Schossnitz) Fl.,p.36, PI. 

 ssii. Fig. 13, differing', however, by the thick substance of the leaves, 

 their larger size, and all the lateral veins going out from the base. 

 The lowest lateral veins are much branched, and not aerodrome, ascend- 

 ing only to above the middle of the leaf. 



Ehamnus Clebueni, sp. nov. 



Leaves thictish, (not coriaceous,) narrowly oval-laceolate, equally 

 tapering" from the middle upward to a long sharp point and downward 

 to a short petiole; pinnately nerved, secondary veins close, slightly 

 arched in passing to the borders, where they abruptly curve along the 

 margin. 



The species is known by a number of finely-preserved specimens, with 

 all the same characters. The leaves are variable in size, the largest 9 

 cent, long; the secondary veins always close to each other, parallel, 

 simple, scarcely 5 mill, distant, abruptly curving quite near the borders, 

 which they follow ; fobrilles numerous, strong, subcontinuous in right 

 angle to the medial nerve. The nervation and form of these leaves, 

 like that of the following species, as also oi Bhamnus ohovaUis, Lsqx., is 

 much like that of some species of the genus Bridelia of the Eujplior- 

 hiacew. When better known by their fructifications they shall probably 

 form a separate group. 



EhA]vinus Goldiai«tus, sp. nov. 



Leaves thickish, subcoriaceous, smooth, entire, broadly oblong 

 ovate, abruptly narrowed to a short blunt acumen, rounded at base to a 

 short petiole. 



These leaves, of which I obtained numerous fine specimens, vary in 

 size from 7 to 15 cent, long, iDroportionally broad, have about the same 

 nervation as the former species, the secondary veins being only slightly 

 more distant, less oblique, (angle of divergence 40 to 45°,) and nearly 

 straight to near the borders, where they more gradually curve. The 

 lowest pair generally branch more or less downward, in anastomosing 

 with their short marginal veins; even the sui>erior veins have sometimes 

 one or two divisions. The species still differs from the former by its 

 more coriaceous substance, its rounded base, and the obtusely acumi- 

 nate point. 



Ehamnus Goldianijs, var. latioe, Lsqx. 



The leaves considered as variety may represent a different species. 

 They are much larger, of a thicker substance, more rounded at the base, 

 and passing to the petiole by a sHort decurrent curve. They much re- 

 semble the leaves relerred to Ulmus (I) uregulcirn^ being intermediate 

 between this and the above species. 



Ehamnus obovatus, Lsqx. 



Already mentioned from the Eaton Mountains, is a truly different 

 species from Bhamnus Cleburnij to which it resembles by the nerva-
