Erect, generally one-half meter high, branched; stem angled, 
glabrous; leaves in the typical form lanceolate, subentire or slightly 
toothed; calyx cylindrical-campanulate, lobes broadly triangular, 
shorter than the tube; peduncles filiform, about 2 cm. long, erect 
with nodding flower, in fruit 4-5 cm. long and reflexed ; corolla 
5-8 mm. in diameter, campanulate, yellow, without a dark spot ; 
anthers yellow, more or less tinged with purple; fruiting calyx 
about 2 cm. long, rounded ovoid, indistinctly 10-angled and pur- 
ple-veined, nearly filled with the berry. 
It is a native of Peru, Mexico, etc. No specimens of the 
typical form have been collected in the United States. The only 
specimens approaching it are those collected by Rugel near St. 
Mark's River, Florida (Herbarium of Missouri Botanical Garden), 
but these have much narrower leaves. 
Two forms are found, however, in the United States, which 
come nearer to this species than to any other, although they 
connect it with P. Wright and P. angulata respectively. 
In the first the leaves are more or less sinuately toothed and 
often more strongly veined, resembling those of the preceding 
species, which it also resembles in general habit and in the sparse 
scabrous hairs on the upper parts, but differs in the small flowers 
(only 3-5 mm. in diameter), which in form perfectly agree with 
the true P. lanceifolia, that is, they are truly campanulate. The 
following specimens belong to this form : 
Arizona: Lemmon, 1881 (in part); Dr. Sonden. no. 375, 1867 ; 
Loew, 1875; Maj. Thomas; Schott,no. 2. (The last two, doubt- 
fully referred to P. Wrighti, by Dr. Gray, Proc. Am. SE Io : 63). 
California: K.C., 1883; C. R. Orcutt, no. 2069, 1 
Texas: E. Hall, no. 504, 1872; Chas. Wright, no. D 1849 
(locality not given). 
The other form connects P. lanceifolia with P. angulata. The . 
leaves are broader than in the typical form and often with sharp 
teeth as in P. angulata, but the very long peduncles, small round 
fruiting calyx, and general habit, make it more nearly related to 
P. lanceifolia. Its range is much more northern than that of the 
typical P. lanceifolia and more northwestern than that of P. angu- 
lata, as can be seen from the following specimens studied: 
Illinois: Vasey, 1862. 
Missouri: Engelmann, 1841; A. Geyer, 1841 (both in the her- `
