Ceanothus fibrillosus, sp. nov. 



Leaves subcoriaceous, ovoid, obtuse, rounded to the base, (petioled 1) 

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

 medial vein, continuous. 



Species related to Ceanothus ovoideus. Gopp., (Schossnitz) ri.,p.3G, PI. 

 xxii, Fig. 13, diflering, however, by the thick substance of the leaves, 

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

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

 ing only to above the middle of the leaf. 



Khamnus Clebueni, sp. iwv. 



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

 tapering from the middle upward to a long sharp i^oiut and downward 

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

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

 margin. 



The specifes 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 of Rhamnus obovatus, Lsqx., is 

 much like that of some sjiecies of the geuus Br Ulelia of the. Uuphor- 

 hiacece. When better known by their fructifications they shall probably 

 form a sepai'ate group. 



Ehamnus Goldianus, sp. nmx. 



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, proportionally 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 superior 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 Goldianus, var. latior, 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 i)assing to the petiole by a short decurrent curve. They much re- 

 semble the leaves referred to TJhmis (?) urcgylaris, being intermetliate 

 between this and the above species. 



Ehamnus obovatus, Lsqx. 



Already mentioned from the Eaton Mountains, is a truly different 

 species from Ehamnus Clehiirnij to which it resembles by the nerva-
