(Lemmon) and on the Arizona Mountains (Lemmon, Pringle), but 

 the larger number of leaves is here a casual occurrence; the branch- 

 lets show the brown-green color noticed above, the leaves are dark 

 green and have the structure described by me in Wheeler's Report. 

 P. Arizonica has glaucous branchlets, thinner leaves, constantly in 

 fives, and of different structure; its cones are thicker and shorter 

 with much more prominent umbos, but not much weight can be put 

 on this last character. — G. Engelmann. 



Some Additions to the North American Flora.— Stellaria 



obtusa, n. sp. — Glabrous, stems weak, prostrate, much branched, 

 leaves subsessile triangular-ovate acute smooth edged i-nerved 

 and the delicate reticulated veins uniting into distinct intramarginal 

 nerves ; flowers single, pseudo-axillary, peduncles nearly as long as 

 the leaves patulous or recurved in fruit, sepals ovate obtuse nerveless 

 scarcely membranaceous on the margin, petals (always ?) wanting; 

 capsule ovate obtuse scarcely exsert, seeds (under the lens) covered 

 with oblong linear pectinate tubercles, dark brown. — Western Color- 

 ado on the tributaries of Gunnison River, alt. 9,000 to 10,000 feet, in 

 damp grounds, T. S. Brandegee. Closely allied to 5. crispa of the 

 northwest but readily distinguished by the form of the sepals, the 

 capsule and the seeds ; in that species the sepals are lanceolate, 

 broadly margined and 3-nerved, the capsule exsert, acutish, the 

 seeds larger, reddish and nearly smooth. 6". borealis, with which 

 crispa has sometimes been united, has a similar calyx, capsule and 

 seeds, but is distinguished by its elongated lance linear leaves, finely 

 serrulate on the edge, the intramarginal nerve very indistinct. 



Campanula planifloka, n. sp. — Erect, glabrous, a finger to a 

 span high from a filiform rootslock bearing similar subterranean sto- 

 lons, usually i-fiowered ; leaves lanceolate to linear-lanceolate 1 to 2 

 inches long. 2-3 lines wide, the lowest ones sometimes broader, all 

 more or less dentate or denticulate; flower erect, calyx turbinate, lobes 

 lance-linear mostly dentate, several times longer than the tube and ex- 

 ceeding the tube of the corolla ; corolla shallow, wide open, 4 times 

 wider than deeo, divided to the middle or beyond ; lobes ovate acute 

 spreading or at length reflexed ; capsule erect ovate or turbinate as 

 long as the connivent calyx lobes or shorter, opening at top — C. 

 Langsdorffiana of the Rocky Mountain floras, not Fischer ; C. Scheuch- 

 zeri, Gray Flora in part. 



Common in Subalpine meadows, near streamlets, at an elevation 

 of 7000 9000 feet Colorado ; Clear Creek vailey, Middle and South 

 Parks. The large and very shallow flowers of a reddish-purple color 

 and the filiform branching rootstocks distinguish this species at once 

 from C uniflora with which I had united it (this journal, 6. 238). The 

 usually erect stems become sometimes decumbent and sev- 

 eral flowered when overgrown. C. uniflora is found only on bare al- 

 pine slopes, usually with Dryas and Silene acaulis at about 12000 to 

 13000 feet alt. It grows from a stout several-headed rootstock, bears 

 deeply campanulate mostly horizontal flowers l 4 inch in length
