ORDERS OF MOSSES. 
1. Sphag-na-les; the Bog-mosses or Sphagnum. 
2. An-dre-se-a-les; one genus of small Mosses in mountain regions. 
8. Ar-chid-i-a-les; only one very short-stemmed species. 
4. Bry-a-les; the common Mosses occurring in Ohio. 
The only book that could be used by beginners in identifying 
Mosses, is Grout’s “Mosses with a Hand-lens,” price $1.10; procure if 
wanted from the author, or if placed in our hands the order will be 
attended to. The Manual by Lesquereux and James could be used by 
advanced students. 
It is earnestly requested that contributions of Mosses for the State 
Herbarium from every County in Ohio be made. Please send an 
ample amount of each kind, enclosed in a temporary paper pocket or 
envelope; with each specimen lay a slip of paper or temporary label, 
giving locality , date and collector's name , also any notes that are made 
with reference to habitat or habit of the plants. The donor’s name and 
other data will be placed on the permanent label accompanying the 
herbarium specimens. 
ADDITIONAL NOTE ON THE SYNDESMON INVOLUCRE. 
A. Wetz stein. 
In addition to the observations made by Mr. F. H. Burglehaus, 
Toledo, Ohio, concerning the involucral leaves of Syndesmon thalic- 
troides Hoffmg., as stated in No. 5 of the Ohio Naturalist, I also 
confirm the contradiction in the habitus of plants growing in Aug- 
laize County with the description in Britton & Brown’s Flora. All 
specimens I found here have no sessile involucral leaves, but petioles 
mostly about one-fourth of an inch in length. Especially the later 
flowering plants, that often grow over one foot high, show petioles 
of more than one-half inch in length, while even the earliest — col- 
lected about the middle of April, and no more than three inches 
high— exhibit distinctly petioled involucral leaves. 
It might be very interesting to find out the range of plants with 
sessile involucres — for I do not at all think this description'of Syn- 
desmon t-o be an error in so carefully prepared a Flora as Britton & 
Brown’s is, the more as the given figure shows strictly sessile 
involucres too.
