tinged white flowers are very pretty and pleasing to the eye. It is 

 also worthy of note, that the fruit heads are early deciduous, leav- 

 ing the terminal tackhead-like torus or base on which the flowers 

 rested entirely naked, showing the conic elevated centre. 



The conico-convex character of the receptacle in H. ^yui^g'ens is 

 even more remarkable than in this species ; at least, this is the 

 character of specimens growing in this vicinity. The involucral 

 scales are clearly in tivo series, instead of one as described. Our 

 specimens are also densely glandular. 



The arachnoid tomentum varies, in same being a strongly marked 

 feature, while in others it is loosly deciduous and unimportaat. 



Dr. Kellogg presented the annexed paper : 

 The following new species of Abronia was recently brought 

 from Carson Valley, Washoe, by Mr. Andrew A. Veatch : 



A. crux-maltce (Kellogg). Fig. 16. Stem a fleshy, creeping 

 vine, with viscid and glandular pubescence. 



Leaves ovate-oblong, somewhat obtuse ; lamina unequal, acute at 

 the base, glabrous, (and pitted under the glass) undulate, on long 

 petioles. 



Perianth salver-form, tube long and slender ; the flattish limb 

 broadly cuneate four-lobed, each lobe deeply subdivided ; the lobe- 

 lets spreading ; mucronate at the bottom of each broad sinus ; the 

 entire limb, in general outline, bears a striking resemblance to a 

 Maltese cross. • 



Flowers four-androus ; stamens unequal, inserted in the tube at 

 the swelled throat, which is closed by a fjew loosely-folded hairs ; 

 anthers oblong ; filament very short. 



A deep purplish rose pink ; the swelled throat a bright emerald 

 green ; tube pink, or whitish flesh-colored, glandular. 



Heads axillary on long peduncles, (about equal to the leaves ?) 

 ten to fifteen flowered. 



Involucre united at the base into a shallow, broadly campanuloid 

 cup, seven or eight parted above ; the segments narrow, ovate- 

 lanceolate, acuminate, nerved, membranous ; margins ciliate, 

 green. 



It differs from A. cycloptera (Gray) in the perigonial form and 

 subdivisions, insertion of anthers, involucre, and perhaps in the 

 oblique character of the leaves, and greater length of the petioles.
