(See 9-10-33) 4-27-34? Cleaerophyllum aureum L. Cote # 222 Bon 134, SW # 480. Bud. Clim Path from below Halte V-M [illegible] towards Ilion R.R. Station. Plant with Aethraeus silvaticus with which it might be confused. Plant has a grayish downy look in contrast with the glabrous, shining more yellow green effect of Q. sil - St. less coarsely ridged text to touch (all is it has short down-pointing brisox) The 3 primary div. if more nearly equal than in Q. sil so that outline is nearly an equilateral triangle. St. not spotted but the lf sheaths (all of which are longer than in Q. sil) the lower ones are rather neatly outlined with red. Lode lf short hairy above & longer hairy below beneath. Petals deeply crimarginate with inflexed tip. (Q. sil almost entire) Invol more. Bracts if involved long acuminate with the fine tips projecting beyond the unopened flo (Q. sil rate with short sharp tips at no stage projecting beyond brds). All Cote suggest this dif. Bracts in both species def. ciliate but C. aureum has also white, rather ruffled edges which Q. sil does not. Petal glabrous. If of the 2 species about equally finely cut tho' C. aureum has tips more oval Cote but not as pronounced as in all Cote. (All found 4-18-34 on upper path to C. leads, but not needed may have been this) 5-31-34 Fl. Clim. Rays of umbel very slender. Stylodium def v rather dark green (or tinged reddish), evident to eye in center of the petals whose edges are well apart. Bracts if involved strongly reddened or even on edges & showing dark beneath the dainty umbellet.
