Diplacus arachnoideus. 



Somewhat viscid throughout, the calyx aucl young foliage 

 whitish arachnoicl-touieutose: leaves lanceolate, entire or 

 sparingly toothed, subcoriaceous : calyx more than an inch 

 long, distinctly widened below the middle and contracted 

 above it; teeth triangular-lanceolate: corolla more than two 

 inches long, nearly white, drying pale buff; tube narrowly 

 funnell'orm; lobes quadrate-oblong, slightly toothed: pod 

 with no apical tuberculation. 



A most beautiful species, with large corollas almost white, 

 found only by the writer, at All Saints Bay, Lower Califor- 

 fornia, April 16, 1885. 



The pale-flowered species of the mountains back of San 

 Diego, and of the northern part of the peninsula, collected 

 by Messrs. Cleveland and Orcutt, are D. longiflorus and D. 

 leptanthus, both excellent species, the former readily distin- 

 guishable from all others by the deeply sinuate-cleft corolla- 

 lobes, the latter differing from D. glutinosus by its linear, 

 entire, coriaceous leaves, and capsule without apical tuber- 

 cle. Of the five southern species recognizable, only D. pu- 

 niceus and D. stellatus have the tubercle. D. arachnoideiLs 

 is readily distinguished from all the old species by its cob- 

 webby pubescence. 



Diplacus Stellatus, Kellogg, Pro. Cal. Acad. ii. 18; Greene, Bull. Cal. Acad. 

 iii. 95, 



Was found again, by the writer, on Cedros Island, last 

 May. The corolla is like that of D. glutinosus in form and 

 color, but only half as large . The pubescence is chiefly a 

 dense, short yellow tomentum. The pod has the tubercula- 

 tion. The species is, in my opinion, w r ell confirmed. 



Verbena lilacina. 



Suffrutescent, much branched, erect, 2 — 4 feet high, spar- 

 ingly short-hirsute and somewhat scabrous; branches stout, 

 4 — 6-angled, sparingly leafy: leaves bipinnatifid, the divis-
