white (in drying changed to cream colored), in dense heads. Pods 
12 mm long, conical, with a long, bent acumen, coriaceous, appressed 
to the rachis, exceeding the calyx about one-half when ripe, appressed 
sericeous-pubescent, the lower half (nearest the rachis) involute. The 
plant is growing on high hills (not on the prairie) Its flowering time 
is about the middle of June. It was found on one of the highest peaks 
of Butte, Benson Co. (type station), and one single plant on a steep hill 
at Minot, Ward Co., North Dakota. 
Differential Characters. A. Lamberti has considerably larger 
size, is always of a more or les grayish aspect, has all the way to 14 
pairs of leaflets, which are broadly to narrowly lanceolate, obtuse or 
acuminate, and the pod is narrowly or broadly oblong; its flowers become 
purplish-blue in drying, its flowering time is about July 1, and it is a 
plant belonging to the plains. A. sericeus differs in its larger size, broad 
leaflets, canescence, and cylindraceous pods of 2,5 cm length. A. Bige- 
lovii has glabrate leaflets and cylindraceous pods, which are thinner, 
longer and short-stipitate.

437. Physostegia formosior Lunell, 1. c., p. 7. 
Stem ascending or erect, simple or branched, hollow, 3—10 dm high 
very leafy (the joints 2—3 cm distant, seldom more). Leaves oblong- 
lanceolate, or ovate-lanceolate, or oblong, 3—10 cm long, 1—2,5 cm wide 
(usually broader than in the other species), serrate to denticulate, acu- 
minate (the lower blunt) at the apex, narrowed at the base, partly 
clasping (the lower having winged petioles), thick, rather succulent, 
glaucescent beneath. Bracts about 1—2 as long as the calyx, ovate, 
acerose-tipped. Spikes dense, many-flowered, becoming 4—15 cm long 
in fruit. Flowering calyx campanulate to top-shaped, its teeth ovate, 
blunt, 1—3 as long as the tube. Fruiting calyx globular, inflated, 6— 
7 mm long, its teeth deltoid, 1—3 as long as the tube (not becoming 
acerose-tipped). Corolla invariably 2 cm long, of a bright gorgeous, deep 
pink color, with a pale spot outside ofthe throat. The plant was found 
in a moist thicket bordering the large timber along Mouse river at
