TERATOLOGICAL NOTES. 
LEPTOsSYNE GIGANTEA, Kellogg. A plant of Leptosyne 
gigantea under cultivation in the Botanic Garden of the 
University of California has this season developed heads 
sufficiently abnormal to be considered worthy of note. As 
was the case with the specimen of Leptosyne maritima 
described by Mr. Howe in the January number of ERyTHEA, 
p. 18, the pales of the receptacle in the examples now before 
me are much elongated and foliaceous: one head has the 
same peculiarities of calyx-tube, ovary and protruding bifur- 
cate style, but differs in that a number of the florets are 
racemed on a prolongation of the axis two inches in length: 
a second specimen has two of the ray- and five of the dise- 
florets, on one side of the head, with ovaries and adherent 
calyx-tubes considerably prolonged, in one case to 16} lines, 
and their styles protruded, in some cases 7} lines, beyond 
the corolla-tube, each bearing a secondary head at the sum- 
mit and a single foliaceous bract at about half its length; 
the total prolongation of the longest floret is thus 2 inches; 
the remaining florets in the primary head are much crowded 
out of position by this abnormal development. All the parts 
of the head are green, but more or less tinged with yellow, 
the ligules exhibiting most color. It should be noted that 
these heads were produced early in June, some time after 
the rainless season had set in. 
Acoseris uirsuta, (Hooker), Greene. On June 11th of 
this year, I found a plant of Agoseris hirsuta growing by 
the roadside near Lorin station, Berkeley, which bore @ 
number of abnormal heads. The ovaries and calyx-tubes 
are borne on pedicels sometimes 5 lines in ‘length, the style 
being thickened and prolonged in some cases 3 lines beyond; 
pedicels, ovaries and styles are clothed with stout simple 
jointed glandular hairs. The most striking feature, however, 
is the development of the pappus into linear foliaceous 
green sepals ciliated with hairs similar to those on other 
parts of the floret, these hairs being very much longer than
