pudescens, Muhl., Agrostis intermedia, Scribn.,* Panicum commuta- 
tum latifolium Scribn. n. var.t and a Lysimachia, nearest to L. 
radicans, but differing in its erect habit and broader and shorter 
leaves, less pointed at either end. 
On the shaded north side of this ledge Heuchera Rugeli, 
Shuttlew., Peramium pubescens (Willd.) C. C. Curtiss, Leptorchis lilu- 
folia (L.) Kuntze, and Asplenium montanum, Willd., were found. 
After several weeks spent in the neighborhood of Poor Fork, 
I resolved to try the valley of the Cumberland at some point 
further down. Leaving my quarters in Harlan county, I had a 
two days’ ride over an abominable road to Wasioto, a small lum- 
ber town fifty-five miles below Poor Fork Postoffice, and about 
one mile above Pineville, the county-seat of Bell county. 
Along the road I saw great quantities of Panicum flexile (Gat- 
tinger) Scribn.,t a species resembling P. capillare, but very distinct. 
About nine miles above Wasioto the Cumberland enters a 
gorge locally known as the “ Narr’s”” (Narrows), through which it 
flows for several miles. Here, on the bluffs, many interesting 
plants were collected. Among them I would mention udus 
odoratus, L., Stuartia pentagyna, ’ Hér., Scutellaria saxatilis, Rid- 
dell, Aster prenanthoides, Muhl., and a Houstonia which I refer, 
doubtfully, to Pursh’s H. zenella.§ 
* «Spikelets not crowded, pedicels capillary, usually much longer than the spike 
lets; flowering glume about 3/ line long, sometimes with a short and delicate dorsal 
awn. 
“Culms erect or geniculate below, 2-3 ft. high; leaves spreading, 2-6 lines 
wide, the uppermost 4-8 in. long; panicle 7-14 in. long, pyramidal, the rather firm 
branches at first erect, those uppermost often spreading while the base of the panicle 
is yet included in the loose, upper leaf-sheath. Spikelets less crowded and smaller — ie 
than in A. eda¢a, with the flowering glume broader at the more rounded apex. 
Intermediate between A. e/ata and A. perennans.” 
+ “ Leaves very broad, panicle large, the widely spreading branches few-flowered.” _

§ Houstonia tenella, Pursh, Fl. Am. Sept. 106? 
Aspect and habit of H. serpy//ifolia, Perennial by extensively creeping, filiform 
rootstocks. Stems slender, smooth, much branched. Leaf 5-7 mm. long, oblong- 
spatulate, obtuse or slightly pointed at apex, tapering into a slender petiole from se : 
one-fourth to twice as long, conspicuously veined; the upper surface, with the margin 
_ and petiole, furnished with scattered, strigose, white hairs; flowers few on very long 
peduncles, deep blue, about one-half as large as those of H. serpyllifolia; tube of — 
corolla very slender, about twice as long as the lobes and 3104 times as dese: as the 
d lobes of the Bio Laser, oly, veigee fruit not seen, ;
