Dear Sir,
While botanizing a few days ago in Plymouth
(Mass) the enclosed specimen of Utricularia was pointed out
to me growing in company with U. purpurea [Utricularia purpurea] & several
other species. U. purp is the only one with purple
flowers described in Beck & Elliot & Nuttall thinks
in his "Genera" that the family is in great confusion.
Flowers of enclosed smaller, [spur?] more obtuse, not
[assesed?] usicula foliage up abundant. than with U. purp.
A second species which I have not examined
particularly, with flowers by [mos & thees?], yellow, slightly
striato, resembling an [?], but cannot be U. [?]
ata of LeConte was also found by me in the same locality
of which I have no specimens at hand. The exception drought
of the summer has [attended?] an excellent opportunity to gather
aquatic plants in the neighborhod.
I understand that Dr. Gray has rec'd the appointment
of Professor of Botany in [?] University in Michigan. You
were so kind as to express a favorable opinion of my

from the J.J. Crooke collection
