Therefore, in the cuts accompanying the species here noted, the 
opened involucre is diagrammatic, and no size relation exists in 
the magnified seed.

In this form the stipules are linear-lanceolate, a pair on each 
surface of the stem, the superior pair with an interstipular gland. 
involucre are not ‘fimbriate,” 
but very hairy; the fact that 
the hairs are as large as those 
of the branchlets causes them 
to appear— in comparison with 
the minute lobes of the involu- 
cre—as if they were fimbriz. 
The fifth gland is replaced by 
a deep notch through which 
passes the recurved stipe of 
the fruit. The seeds are pink- 
ish, sharply quadrangular, 
0.8™" long, o.4™™ broad, the 
concave facets marked by several transverse ridges, some of 
_which are extended but part way across the facet. 
Dr. Palmer’s [360 Durango 1896] specimens are the most 
robust that I have seen. Dr. Schott’s Yucatan 56 and 57 are 
much smaller plants, although the leaves and involucres are of 
the same size as those in Dr. Palmer’s form. Dr. Gaumer’s 
Yucatan 315 is a counterpart of those of Dr. Schott, but his 1003 
seems to be a transition to the species itself. Dr. Ridell’s Key 
West 1839 is the same as the Schott Yucatan form, while Val- 
dez Yucatan 2 is very near Dr. Palmer’s Durango plants.
