616 BIcKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
obtuse, often spatulate-linear, and usually on more obvious 
petioles; the primary inflorescence is of more delicate and open 
structure, the flower buds elliptic in form rather than ovoid, the 
calyx becoming notably larger, 8-10 mm. long, and often strongly 
reddish-tinged, thus equaling in length the largest calices of 
C. canadense as well as corresponding in color, although with 
narrower sepals and wanting the characteristic pilose hairs; the 
narrow outer sepals are shorter than in C. majus, and the even 
_smaller petals are of rather a brighter yellow; the primary capsules 
are smaller, thinner-walled, and less broadly ovoid, longer than 
wide instead of wider than long, and are without the umbonate 
tip; it is, in fact, much more like the capsule of C. canadense, 
although smaller and narrower; the papillose seeds are also much 
like those of C. canadense. 
There is nothing in all this that denotes the plant to be neces- 
sarily of mixed strain, nor do my observations lead me to believe 
that it is a hybrid. It does indeed possess in combination the 
early flowering time of Crocanthemum canadense and the smaller 
pale yellow flowers of C. majus, together with the slender branch- 
ing of the one and the clustered petaliferous flowers of the other, 
yet its capsule has not its counterpart in that of either, nor is it 
intermediate with them, being smaller and less broadly ovoid. 
The plant stands apart from these companion species also in its 
small size and more delicate structure, in the prevailing form of 
the leaves and in its non-cespitose habit. Its slender stems, 
although sometimes loosely clustered, commonly arise at distinct, 
even remote intervals along tortuous elongated rootstocks, forming 
open groups or larger patches, sometimes several feet in diameter. 
It is rarely found associated with more than one of its close allies, 
often, indeed, occupying territory where not either one of & 
others is found at all. 
The relationship of Crocanthemum propinquum to the little- 
known C. georgianum of the southern states is evidently close, 
although, according to Dr. Small, the latter possesses the very 
distinct character, as compared with the northern group of species, 
of bearing pe petaliferous and apetalous flowers in the same 
clusters.
