394 SUPPLEMENT. 



elongated and protruded in age (carried up by the enlarging capsule): seeds from short-oval 

 to oblong-oval. — N. rarnosissimus, Torr. Hot. Mex. Bound, t. 35, is one of the forms of this. 



— From Middle and through S. E. California to the S. W. border of Texas. 



N. longiflorus, Gray, p. 3. Habit of the last preceding form, well marked by its longer 

 corolla and elongated free capsule. 



N. rigidus, Curran. Stout and coarse for the genus, rather fleshy and thickish-leaved, 

 purplish : calyx with triangular-subulate lobes somewhat surpassing the short corolla, and 

 tube adnate quite to the middle of the remarkably large (2 lines wide) globular capsule : 

 seeds (nearly half-line long) oval, under a good lens broadly costate and the ribs cross-barred 

 as in N. rarnosissimus, var. montanus. — Bull. Calif. Acad. i. 154. — Nevada, on Geiger's Grade, 

 near Virginia City, Mrs. Layne-Curran. This might throw some doubt on the following 

 genus ; but it has the bivalvular dehiscence of Nemacladus. 



1 1 . PARISHfiLLA, Gray. (The discoverers, Samuel B, and William 

 F. Parish, of San Bernardino, California.) — Bot. Gazette, vii. 94, & Proc. Am. 

 Acad. xix. 83. — Single species. 



P. Californica, Gray, 1. c. A very small and depressed winter annual, almost glabrous, 



with leaves and flowers glomerate in a radical tuft, whence proceed radiately spreading and 



. naked branches bearing similar tufts : leaves spatulate, the primary ones 3 to 5 and the later 



only 2 lines long : flowers short-peduncled : corolla white. — Rabbit Springs, in the Mohave 



Desert, California, May, 1882, the brothers Parish. 



1 2 . HCWfiLLI A, Gray. (The discoverers, Joseph and Thomas T. Howell.') 

 — Proc. Am. Acad. xv. 43. — Single species. 



H. aquatilis, Gray, 1. c. Aquatic herb, with iVaias-like foliage, submersed, or summit of the 

 stem and uppermost flowers emersed, with some scattered or verticillate branches : submersed 

 leaves linear-setaceous and elongated, mostly alternate, entire; emersed ones shorter and 

 broader, sometimes 1-2-toothed : flowers axillary, short-peduncled : only submersed capsules 

 known, these half-inch long. — In stagnant ponds on Sauvies Island, Columbia River, at the 

 mouth of the Willamette, Oregon, J. Sf T. T. Howell. 



2. LOBELIA, L. 



L. paludosa, Nt/tt., p. 5. Exclude the statement, "even four feet high," and add : — 



Var. Floridana. The larger form, 2 to 5 feet high : tube of corolla 3 or 4 lines long. 



— L. Floridana, Chapm. in Bot. Gazette, iii. 9. — Common in Florida, also Louisiana accord- 

 ing to coll. Drummond. 



L. Gattingeri, Gray. (Next to L. appendiculata.) Flowers smaller than in L. appendicu- 

 lata : lobes of the calyx attenuate-subulate, not at all ciliate, obscurely appendaged at base 

 only by a minute callus on each side, in fruit equalling or longer than the mature capsule 

 (not " shorter ") : pedicels often bracteolate. — Proc. Am. Acad. xvii. 221. — Cedar barrens 

 of Middle Tennessee, Gattinger. 



L. Cliffortiana, L. Transfer the reference "Michx. Fl.," and therefore the syn. L. Mi- 

 chauxii, to the var. Xalapensis. 



3. PALMEEELLA, Gray. 



P. (Mbilis, Gray, p. 8. Not rare from mountains near Santa Barbara (Mrs. Cooper, 1878) 

 and San Bernardino Co. to Lower California. An interesting addition to the generic char- 

 acter, detected by Mr. Nevin, is that the throat of the corolla on the (apparently) upper side 

 bears a nectary, as if an adnate spur, forming a narrow imperfectly tubular cavity, reaching 

 down to the insertion of the filament-tube on that side.
