Watson, Proc. Am. Acad. xvii. 375. — Higher Cascade Mountains, on the eastern side, 

 Washington Terr., Watson, Brandegee. 



D. laevigata, Gray. Leaves glabrous, or sometimes with a few minute and scurfy decidu- 

 ous branched hairs, not at all ciliate, quite entire, thick, oblong-lanceolate, obtuse, mainly in 

 rosulate radical or simply proliferous clusters : flowers in 2-5-rayed pedunculate umbels : 

 bracts of the involucre oval or ovate, short : corolla-tube almost twice the length of 

 the calyx. — Proc. Am. Acad. xvi. 105. — Mountains of Oregon, Howell, Mrs. Barrett, 

 Suksdorf. 



D. montana, Gray, p. 60. Leaves wholly destitute of forked hairs, glabrous or nearly so, 

 but margins ciliolate with short simple bristles, linear or lanceolate, small (1 to 3 lines long), 

 very crowded on the crowns of the pulvinate-cespitose branches, or in the larger and looser 

 plants in successively proliferous tufts : peduncles solitary and simple (or rarely in pairs 

 from the rosulate tuft), naked and 1 -flowered, and the calyx often unibracteolate (in one case 

 a second flower sessile in the axil of the bract) : tube of the corolla barely or hardly equal- 

 ling the calyx. — Common in N. Montana, recently coll. by Canhj, Brandegee, Scribner, &c, 

 both in pulvinate-depressed and in rather open and proliferous forms. 



D. arctica, Hook., p. 59. Like the preceding in the ciliate leaves, but said to have the 

 habit (of inflorescence 1) of D. nivalis. 



5. ANDR6SACE, Tourn. P. 60, before A. occidentalis, add: — 



A. Arizonica, Gray. Exiguous : scapes filiform, some erect, some decumbent and as if 

 stoloniform, bearing few or several elongated capillary pedicels : radical leaves lanceolate or 

 oblong, thin : calyx-lobes foliaceous and much accrescent in fruit, ovate, longer than the 

 short-campanulate whitish tube : corolla minute : seeds 5 or 6, comparatively large. — Proc. 

 Am. Acad. xvii. 222. — Mountains of S. Arizona, Pringle, along with A. occidentalis, its near 

 relative. 



8. L YSIMACHIA, Tourn. After L. Fraseri, p. 62, add : — 



L. vulgaris, L., — a coarse and tall European species of this section, pubescent and branching, 

 with ovate-lanceolate distinctly petioled leaves, leafy panicle, and glandular filaments united to 

 near the middle, — has escaped from gardens and become naturalized in one or two places in 

 Eastern Massachusetts. 



11. CENTtTNCULUS, Dill. P. 64, add: — 



C. pentandrus, E. Br. Pedicels equalling or surpassing the ovate leaves : flowers com- 

 monly 5-merous. — Prodr. 427; Griseb. Fl. W. Ind. 390. C. tenellus, Duby in DC. Prodr. 

 viii. 72; Chapm. in Bot. Gazette, iii. 10, & Fl. ed. 2, 634. Anagallis pumila, Swartz, Fl-

6. CYCLADENIA, Benth. 



C. hlixailis, Benth., p. 83. An intermediate form, found in Southern Utah, by Siler, shows 

 that the pubescence is inconstant, and requires 

 Var. tomentosa to take the place of the second species, C. tomentosa, Gray.
