HE Horticultural Society, in 1843, sent Mr. Hartweg to collect 
new plants in South America, and more particularly in Mexico 
and California. Some very interesting particulars of his researches 
are inserted in our last year’s volume. ‘The results of his industry 
were rewarded with the discovery of many of our handsomest annual 
flowers, an enumeration of which are given in the extracts above 
referred to, and to which we direct our reader’s attention. In his 
remarks on an excursion to “ the Butes,” an isolated group of mountains 
in California, he states, ‘“‘ A ride of fifteen miles brought to the foot of 
the mountains. The lower range, as in the former visit higher up the 
valley, is occupied by a Leanothus, a few live oaks, and Pinus Sabi- 
niana. Following a small rivulet, I found there a Mentha, and another 
labiate plant, Stenactis, a shrubby Labiate tinctoria. This new species 
of Collinsia is of stronger growth, though less striking, than C. bicolor ; 
it grows chiefly on the dry sandy bed, or on the banks of the rivulet, 
and produces its yellowish flowers, mottled with purple, much later 
than C. bicolor. On a subsequent occasion, when I returned to this 
place to procure seeds of it, my hands were stained yellow by the 
glandular hairs which cover the seed pods, from which circumstance I 
named it Collinsia tinctoria. Another very interesting plant I found 
on this excursion (in May, 1844) is Nemophila speciosa, with white 
petals, one-third of which is tipped with violet-purple. It grows 
generally near rivulets, or in damp and partly shaded places. If the 
few seeds I procured should vegetate, it will prove a great acquisi- 
tion to that handsome genus.” Mr. Bentham considered that the 
specific title ‘ speciosa,” given by Mr. Hartweg, was not quite as 
appropriate as maculata ; he rejected the former and adopted the latter.
