In the same locality, I found in great abundance the rare Utah 
ferns Aspidium Lonchitis, Polypodium vulgar e (typical form and var. 
occidentale) diXid Adiantum p€datum. The last has remained till this 
year unseen since its discovery by Mr. Watson ten years ago. The 
specimens are the same robust ones that are so familiar in the dells 
of Iowa. 
Cleome sparsifolta, Wats. — I have this in excellent specimens. 
Mr. Watson's specimens were evidently too old, as the figure in Bot. 
King does not represent the species accurately. The bracts (so con- 
spicuous in the figure), are inconspicuous ; they are seldom elliptical, 
and are always acute. The leaves (which should appear all over 
the figure, except at the very base) have petioles 6" to 9" long, and 
three oblanceolate, acute leaflets. The petioles gradually lengthen 
toward the base of the stem, where they are i' to 2' long. The 
leaflets toward the base become shorter and less acute, till at the 
root they are spatulate-linear, very obtuse and mucronate. The 
siliques are often 18" long. The plant is 2"" or more high.

Notes on Michigan Plants.— At Adair, about eight miles west of 
St. Clair, I spent several weeks last summer, and made a series of 
notes irelative to the flora of that region. 
It is said to have been once covered with forests of the white 
pine {Pums Sirobus), but these were thinned out by the lumberers, 
and finally destroyed by a great fire which ravaged this section of 
country. I found, however, a (ew trees, 20-30 feet high, which 
may have grown from seeds dropped after the fire. 
Instead of the old forests, dense growths of Populus tremuloides, 
grandidentata and monilifera have sprung up in many places and 
become characteristic of the burnt regions. An occasional Bctula 
lenta and lutea is sometimes found. The result has been an irregular 
growth of timber, allowing the passage of the sun's rays and a con- 
sequent growth of many sun-loving plants, offering a striking con- 
trast to the ancient sombre forests which usually meet our eyes at 
this lime of the year. In marshy places are found Ranunculus 
alism^fi 
Valerandiy var. Ameri- 
canus, Myosotis laxa and Aspidium ISfoveboracense. In clearings 
Gnaphalium purpureum is not uncommon, Epilobium spicatum and 
£rechf kites hieracifolia are the first to occupy burnt grounds. 
Hypericum Canadense, var. majus, Rubus hispidus, Lonicera parviflora^ 
var. Douglasii, Pyrola elliptica, the crimson form of Monotropa 
Hypopitys, Collinsonia Canadensis, Hedeoma pulegioides. Euphorbia 
hypericifolia^ Spiranthes Romanzoviana, Oakesia sessilifolia and 
Osmunda regalis belong to the flora. Daucus Carota has become 
naturalized in the country west of Adair. Only t\Vo trees of Lirioden- 
dron Tulipifera were observed. I also found an Elodes which, I 
think, explains ih^ petiolata (?) in Wheeler and Smith's catalogue. 
It was sent at the time to Prof. Thos. C. Porter, and I think that 
the facts cannot be better stated than by copying the words he used: 
It is the same thing which I collected years ago in Central Penn- 
sylvania, and Garber on Lake Conneaut, Crawford Co., in 1868.
