ASTER MULTIFORMIS 371 
A. elaeagnius pale and scurfy beneath with more strigose hair, and 
more irregular in leaf-form and inflorescence; A. Masardiensis is 
much taller as well as downier, of different color and leaf-form. 
Other species of the Macrophylli are still more conspicuously 
different 
72° Arrest-forms. Arrest of leat development is very common 
in A. multiformis, the suddenly diminished little leaves above pre- 
senting quick transitions from slender-petioled and wing-petioled 
to broad sessile bases. 
72° Petiole-flowered form. A peculiar arrest-form or a dwarf 
state, in which the few heads (or single head) seem to spring from 
the middle of the petiole of the upper leaf; that petiole continuing 
the direction and form of the stem exactly, while the real con- 
tinued-stem breaks away from the petiole at an angle and with 
diminutive branch-like aspect, extending then for an inch or two 
and bearing 6-12 dwarfed little leaves (chiefly of form 3, or 5, p 
369. Similar development is occasional in A. biformis ; see p. 331. 
W. N. Y., Pt. Gratiot, ' 96-1904, every year, with the type. 
72* Biculminate form. Large lower leaves are followed by little 
leaves which increase upward to the inflorescence, there forming a 
second culmination of foliage. The smallest leaves thus appear 
at the middle of the stem; they are usually oval or orbicular. 
Leaf-form as a whole broader than in the type.

72° Acutifolial form. Thin; most leaves incurved-acuminate 
into a straight caudation; radicals various, large and long, broad 
and small, regular or lop-sided, their teeth big and remotish or 
very remote.  Leaf-texture very thin, very rough, very hirsute to 
touch, not firm nor dense. Hair abundant, often obvious all over 
the stem and over the leaves beneath. Glands very few, mainly 
near the top. Bracts resemble those of A. divaricatus, being green 
and thin, roundish cuneate, with pale edges. Inflorescence com- 
posed of segregated clusters. Resembles A. divaricatus deltoideus 
and A. persaliens. A possible hybrid?

72° Rubicund form. Intermediate to A. macrophyllus L., hav- 
ing greater thickness and roughness of leaf, broader outlines, and 
more red in rays and bracts, the erect tubular young rays con- 
tinuing red till a brief duration of violet comes at expansion: in 
this redness agreeing with the next species. Dunkirk.
