North Mexico, valley of San Luis Potosi (Schaffner, 69; Parry & Palmer, 701); 
Sout Mexico, Jalapa (Graham, 270). Hb. Kew. 
Bentham and Hooker (Gen. Plant. ii. p. 908) limit the genus Bouchetia to one 
species, and identifying, erroneously as we believe, Galeotti’s 1476 and Bourgeau's 68 
with B. procumbens, refer that to Mierembergia. The specimens we have referred to 
this species are, like those of B. erecta, easily distinguished from any Merembergia by 
the gradually tapering tube of the corolla, and by the longer, perfectly free stamens 
inserted lower in the corolla. 
26. NIEREMBERGIA. 
Nierembergia, Ruiz et Pav. Prody. p. 23, et Fl. Peruv. et Chil. t.123; Benth. et Hook. Gen. Plant. 
li. p. 908. 
About twenty herbaceous species, inhabiting America, chiefly in the mountains of 
Mexico and western South America, a few occurring in extratropical South America. 
1. Nierembergia angustifolia, H. B. K. Nov. Gen. et Sp. iii. p. 9, t.198; DC. 
Prodr. xiii. 1, p. 586. 
Norta Mexico, in marshes around the city of San Luis Potosi (Schaffner, 610); 
Sour Mexico, near Real del Monte, 8000 to 9000 feet (Humboldt & Bonpland), valley 
of Mexico (Bourgeau, 68), Morelia, 6000 feet (Galeotti, 1476). Hb. Kew. 
Bentham and Hooker (Gen. Plant. ii. p. 908) refer Galeotti’s 1476 and Bourgeau’s 
68 to Bouchetia procumbens, DC., which, however, is a distinct plant, and, as we believe, 
a true Bouchetia: see our remarks under that genus.

Leptoglossis (Brachyglossis) coulteri, A. Gr. in Proc. Am. Acad. xii. p. 165. 
SoutH Mexico, Zimapan (Coulter, 1346). Hb. Kew. 
We regret being unable to follow Dr. Gray in referring this and the next to Lepto- 
glossis, this especially being so like a typical Nierembergia as not to be easily distin- 
guished from such species as N. veitchii, Berkeley in Bot. Mag. t. 5599, and WV. filicaulis, 
Lindl. Bot. Reg. t. 1649. Moreover the typical species of Leptoglossis are so different 
in habit, and in the form of the corolla, that we regard the character derived from the 
stamens as of secondary importance, particularly as some other species of Merembergia 
exhibit a tendency to inequality in the size and degree of development of the stamens.
