2. T. leucautlia, Cxreene, Pittonia, i. 301 (1889). Habit of the preced- 

 ing, but glabrous except a glandular pubescence on tlie more ample and 

 loosely dichotomous inflorescence ; branches more or less distinctly 

 quadrangular : leaves linear, acute, little exceeding the internodes (1 in. 

 or more) ; stipules deltoid-ovate, acuminate, 2 — 3 lines long : pedicels 

 1 in. long or more, at length abruptly defiexed, subtended by reduced 

 and linear-subulate bracts : sepals 2 — 3 lines long, with broad scarious 

 margins : corolla ^^ in. broad or more : filaments broadly subulate and 

 almost petaloid : apex of capsule exserted, distinctly triquetrous : seed 

 brown, smooth, of round-obovate outline and with a broad scarious 

 wing. — Confined to clayey subsaline or alkaline plains of the interior ; 

 plentiful at several points on the lower San Joaquin, also on the eastern 

 side of the Livermore Valley, and southward perhaps throughout the 

 State ; for Mr. Parish collects it near San Bernardino, It is the only- 

 showy species. Mar. — May.

3. T. pallida, Greene in Britt. 1. c; also T. macroiheca, var. scariosa, 

 Britt. 1. c. Prostrate, diffusely branching and densely cespitose, the 

 geniculate stems stoutish below, often naked and appearing suf?rutescent ; 

 herbage pale, densely pubescent and very viscid : primary leaves oblong- 

 linear, very acute, J/g in. long or more ; those of the fascicles shorter and 

 relatively broader ; stipules ovate-acuminate, often 4 — 5 lines long : fl. 

 either scattered singly on short branchlets or in reduced terminal cymes : 

 pedicels i^ in. long : calyx }4 in. long : petals lilac : capsule as long : 

 seeds obliquely orbicular, light brown, very smooth, broadly margined. — 

 On high and dry clayey bluffs overhanging the ocean in San Francisco 

 Co., also across the channel in Marin. In floral character quite like 

 T. macrotheca with which it has been long confounded, though in vege- 

 tative characters very distinct. It appears to have been collected only 

 by Dr. Torrey (n. 41), Mr. Meehan (at Monterey ?) and the present 

 writer. May — July. 



4. T. Clevelaiidi. Prostrate, slender, very diffuse, forming deep 

 green mats }4.—l}>i ft. broad ; herbage pubescent but only slightly 

 viscid : leaves narrowly linear, the fascicled ones subulate, all equalling 

 or exceeding the internodes : fl. in terminal cymes only, small (I3' in. 

 broad), pure whit«. — The plant to which I here give a provisional name as 

 a probable new species was formerly abundant on rather sandy uplands 

 about San Diego, and occurs sparingly on gravelly knolls at the Presidio, 

 San Francisco. It is a part of the T. rUtosa, Britt., and may possibly be 

 proven identical with the South American plant. But the name is so 

 inapplicable to ours, that I believe the two will be found distinct. 

 According to Dr. Britton, it has been found also at San Jose. Its close- 

 matted habit, profusion of fascicled leaves, and clear white corollas, as
