Falls of the Ohio, ]\fr. Win. Jours! (corninuiiicaled hy Dr. Clapji.) 

 June. — Stems al)oiit 2 feet in lenu;!!), rather stout, hrancheil from the \m»c, 

 ditliise or aseeiulini;;; the young braneiies, j)etioles, ealyx, Are. a littb; pubes- 

 cent with ap|)ressed iiairs. Lower petioles about th<! leii'ith of the leaflets 

 (an inch or more) ; the upper ones very short. Letifleis reticulated, some- 

 times reiuse, entirely destitute of fjlands, as is the whole plant. Sii|)ules of 

 the lower leaves al)out halt the let)!:;th oi' the petioles, obtuse ; the up]iermost 

 as long as the petioles, acuminate. Flowers rather large, apparently jinle 

 blue, the keel and wings ti]>ped with violet-purple. Fruit not seen. — A 

 very distinct species. Tlie habit of tlie plant is somewhat like Trifolium 

 pratensc. 



24 (bis). P. pln/so(/es (Dougl. I) — Add syu. Hook, i^ Ani.! hot. Brrrhry, 

 suppl. p. 333. — Our ])lant is the same with Hooker's, whicii was deserilied 

 from specimens in an advanced state, when the inflated calyx becomes as 

 long as the withered corolla. 



25. P. orbicularis (Lindl. I) — Add syii. Ifook. Sf' Arn. .' I.e. — Leaflets 

 roundish-cuneiform, dolled. Stipules small, membranaceous. 



Under the name of P. macrostachya two speeies have been confounded, as 

 we had sus])ectc(l. Tiiese Hooker has recently distinguished, and we there- 

 fore substitute the following amended characters. 



26. P. macroslacliijd (DC): pubescent; stem, petioles, anrl ])edunrles 

 scabrous with elevated glands ; leaves piunately 3"foliolale ; leaflets laneco- 

 late-ovale, thickly doited on both sides, acuminate, acUle at the base; sti- 

 pules small, lanceolate ; spikes cylindrical, dense, very long, on peduncles 4 

 times the length of the leaves; the rachis, calyx and bracts very villous 

 Avilh mostly blackish hairs; cah'x not glandular, longer than the rhombic 

 acuminate-cuspidate bracts, the lower tooth nearly as long as the corolla. — 

 DC! prodr. 2. p. 220 ; IIool:. S^- Arti. ! hot. Bcechey, suppl. p. 332; not 

 of Lindl. 



Nooika, Lagasca, ex Dc Candolle ! California, Dovf^las! — The spikes 

 are often 4 inches in lenglli, and narrow; the villous ])ubescence which is 

 blackish in Douglas's plant, is whitish in the specimen of De Candolle, bflt 

 there is no other difference. 



26 {a). P. slrohilina (Hook S^- Arn.) : stem, petioles, slijjules, peduncles, 

 and bracts hirsute, and scabrous with fuscous siipitale glands; leaves pin- 

 nately 3-foliolatc ; leaflets broadly rhoud)ic-oval, nearly glabrous above, 

 dotted with glands, clothed with a soft pubescence beneath; petioles elonga- 

 ted; stipules large, broadly ovate, cuspidate-acuminate, membranaceous; 

 spikes oblong, large and thick, on iiedunclcs scarcely longer than tlie leaves; 

 bracts broadly ovate, acuminate, glandular, larger than the flowers; calyx 

 hirsute with mostly blackish hairs; the lower tooth as long as the corolla, tjte 

 others unequal. — 'Hook. S; Am.! hot. Bcecheij, suppl. p. 332, t. 80. P. 

 macrostachya P. ? of this work. 



0. stipules and bracts much smaller. — P. macrostachya, Lindl. ! hoi. rrff. 

 t. 1769, not o( DC. 



California! Douglas .'—Stem striated, tall. Leaflets 2-3 inches long. 

 Spikes thick, about 2 inches long; the bracts conspicuous, and often almost 

 concealing the large purple flowers. Ovary and style clothed with villous 

 hairs. — Very different from the original P. macrostachya, which we had not 

 seen when our account of the genus was published. The P. macrostachya 

 of Lindley we have seen in cultivation, but have no specimen. Judging
