ovate-oblong or elliptic in outline, papery, almost entirely superior, 
2-valved at the apex. — Shaded banks near Guadalajara; September, 
1889 (n. 2985); also near Cardenas, San Luis Potosi, 1890 (n. 3302). 
This plant, which was distributed under the name of Laurentia Michoa- 
cana, var. ovatifolia, appears on further examination to be distinct from - 
n. 3337, of which it was at first regarded as a variety. It has the 
habit of a Lobelia, but the corolla is split behind only part way to the 
base. While in the limb of the corolla and the insertion of the sta- 
mens it agrees rather closely with Palmerella, the corolla-tube is short, 
as in Laurentia. The plant thus furnishes additional evidence that 
Schénland is right in uniting the two genera. 
Mr. Pringle’s n. 3337, the plant which was distributed as Laurentia 
Michoacana, Robinson, is without doubt closely related to the species 
just described, but is distinguished by its sessile leaves of considerably 
different form and toothing. It appears to be identical with Parry & 
Palmer’s n. 557, which Hemsley refers to Lobelia micrantha, HBK., 
and with Mr. J. Donnell Smith’s n. 22, the Lobelia Tiirckheimii of 
Vatke (unedited ?). The corolla in all these plants, however, is cleft 
only from one third to half-way to the base, a character which should 
certainly exclude them from Lobelia, as at present defined by Ben- 
tham & Hooker, Baillon, Schénland, and others. While the speci- 
mens in question agree in most points with Laurentia ramosissima, 
Benth. & Hook. (Lobelia ramosissima, Mart. & Gal.), they are dis- 
tinguished by their much smaller flowers. Unfortunately, however, 
Martens and Galeotti have characterized, under the name of Lobelia 
parviflora, a plant which also appears from their rather unsatisfac- 
tory description to differ from their Lobelia ramosissima chiefly in the 
same respect, namely the shorter corolla. This being the case, it seems 
best that all three of the numbers just cited should be for the present 
doubtfully referred to Lobelia parviflora, Mart. & Gal., since it is 
highly probable that the type of this species will be found on investi- 
gation to be a Laurentia, just as the Lodelia ramosissima of the same 
authors has already proved. 
Loseria Novetia. Stema foot high, branching, with a few rather 
large leaves near the base, almost naked above: leaves petiolate, 
broadly ovate, acute or obtusish, rounded or subcordate at base, un- 
dulate and finely mucronate-denticulate, hispid on both sides, scarcely 
paler beneath, 24 to 3 inches long, 2 inches in breadth ; upper leaves 
€w, much smaller, sharply and doubly denticulate ; racemes long, Se- 
Sand 3 bractlets minute, scarcely exceeding a line in length; pedicels 6 to me 
9 lines long: calyx-tube turbinate, in fruit equalling or surpassing the
