An introductory paragraph to this series may be short as will be the

notes that follow. Suffice therefore to say that from time to time the

field jottings and short notes of observations on the plants of our

State flora will be presented. Not only those made myself but others

which may be kindly communicated to me for this purpose by botanists,

amateurs, students and other observers will find a place in the series.

An especial invitation is extended to pupils in our High Schools and to

teachers throughout the State to contribute suitable material which in

many cases may be of great interest and importance. Sub-heads will be

used thus making it possible to scan the notes easily.

PUCCINIA SMILACIS.--This Black Rust which has the various

species of Green Briar for its host, was noticed in extraordinary

quantity the past season in Scioto, Adams and Brown Counties. It

was abundant only on Smilax glauca--called in that region the Saw

Brier--but not uncommonly occurred on S. hispida and S. rotundifolia.

It was also remarkable in this respect namely that the teleutospores

(the black or winter spores) were excessively abundant: the uredospores

(red or summer spores) could be found only when search was made. The

observation here recorded pertains to the first half of the month

of November. I have occasionally noticed uredospores in quantity on

Smilax leaves in the various parts of Ohio but never before found the

winter-spores common. It should perhaps be added parenthetically that

_Dicœoma_ having the priority over Puccinia is really the generic

name that should be used, but the commoner designation may here be

tolerated.

QUERCUS ACUMINATA.--The Chestnut or Yellow Oak (name in Gray’s Manual

Quercus Muhlenbergii) is described as “a tall tree with thin _flaky_

bark” (Gray), or “a tree with gray _flaky_ bark” (Britton); and in fact

many of the White Oaks are said to have “_flaky_” bark. The Quercus

acuminata is very abundant in central Ohio and is of common occurrence

in many parts of the State. It is rare that the “flakiness” of the bark

or a tendency to separate in plates, is pronounced or conspicuous in

our Chestnut Oak trees. The single good example I have found is here

shown in Fig. 1 reproduced from a photograph of a specimen growing in

Hayden’s ravine near Columbus. Both trees shown are the same species

but the smaller one has merely furrowed, not flaky, bark, and it is

a fair representative of the trunks of this Oak as they occur in our

vicinity. The usual form of bark is perhaps more clearly shown in

Fig. 2, which is from a photograph of a large tree standing near the

Horticultural Hall of the Ohio State University. This specimen has

leaves remarkably narrow for Q. acuminata but the trunk is similar in

appearance to the trees which have broad leaves.

HELIANTHUS MAXIMILIANI.--Maximilian’s Sunflower whose habitat

and range are given in Britton and Brown’s Illustrated Flora as “on

dry prairies, Minnesota, and Manitoba to the Northwest Territory,

Nebraska and Texas” may be said to be out of place in Ohio. Yet Mr. R.

F. Griggs found it (a single plant) in the season of 1900 (cf. O.

S. U. NATURALIST, 1:16) at Sandusky, Erie County. In a package of

interesting plants sent to the State Herbarium recently by Mr. Otto

Hacker, fine herbarium specimens of this conspicuous species were

furnished. Mr. Hacker says that he observed it near Painesville (Lake

County) six or seven years ago by railway tracks, where it is still

flourishing.

LOTUS CORNICULATUS.--This European Lotus, with such common

names as Bird’s foot, Trefoil, Ground Honeysuckle, Bloom-fell,

Crowtoes, Cat’s-clover, and Sheepfoot, was collected at Painesville

by Mr. Otto Hacker in nursery grounds. This is the second time this

waif has been recorded for Ohio, the first case being reported by Mr.

Ricksecker, of Oberlin.
