\ 



ccis scarcely any: calyx campanulate {G-y mm. lon^^)^ 5 -toothed, 

 the upper teeth deltoid ovate, acute, the three lower subulate and 

 nearly twice as long", sparingly hairy : corolla showy. 



Orc\gon and Washington. The type is Flett's no. 2;6, col- 

 lected at Tacoma ; other specimens studied are : 

 Oregon, Hall, no. 1 17. 



A\^ashington, Henderson, Cooper. 



The type of this species is stouter, less hirsute and has lar^ 

 (15-20 mm. long) more oval leaves which are not so acute at the 

 ends. The flowers are also smaller, commonly solitary and nearly 

 sessile. The calyx is more deeply cleft, and the teeth long;er, es- 

 pecially the upper. It has a more southern range from Santa 

 Cruz to Oregon. 



(Tpr 



Hydrophyllum congestum 



_ Stem 20 30 cm. high, rather weak, pubescent with sparse crisp 

 hairs, sparsely branched : the cauline leaves 2-3 in number (20 

 cm. or less in length), pinnately 5-foIiate, on rather long petioles ; 

 leaflets ovate-oblong, acute, the upper much larger and broadly 



ovate, all cleft incised and sharply toothed (3-5 cm. long) green 



and strigose above, crisp-pubescent and paler beneath : flowers 

 in dense and nearly sessile clusters ; the peduncles very short (15- 

 20 mm. long) ; pedicels slender (8 mm. long), finely and crisply 

 pubescent with tawny hairs : calyx small '(5 mm. long), cleft 



nearly to the base, sinuses rounded, naked ; lobes linear, obtuse 

 (rarely acutish), i -nerved, margins and surfaces densely clothed 

 with tawny hairs intermixed with shorter ones : corolla short (8 

 mm. long) glabrous, cleft two-thirds of the way to the base, lobes 

 oblong, rounded or slightly retuse at the appex ; folds extending 

 two-thirds of the way up, rather narrow, cellular-striatc and glandu*'- 

 lar-ciliate : stamens with slender filaments i 2 mm. long ; anthers 

 oblong (2.35 X 1.25 mm.) cordate at the base, rounded and apiculate 

 at the summit : style forked at the tip, 12 mm. long. 



Collected near Tacoma in 1896. 



This species resembled //. Virginicuin but differs In the more 

 numerous leaflets, in the brownish hirsute covering of the nearly 

 sessile inflorescence, and the densely hirsute calyx lobes. It 

 also resembles H. occidoitalc Gray and //. albifrons Heller from 

 which it differs principally in the short peduncles and form of the 

 leaflets. //. tcniiipcs Heller has very long peduncles, the calyx Is 

 merely ciliate, and the hairs are not distinctly tawny.
