2a2 THE RARITAN FLORA.<br />
this nucleus three membraneous wings are usually attached.<br />
<strong>The</strong>se wings usually diverge from each o<strong>the</strong>r at angles <strong>of</strong> about<br />
45°; <strong>the</strong>y are broadly linear, obovate OF ovate in outline, with<br />
broadly rounded, almost truncate tips and narrowed somewhat<br />
toward <strong>the</strong> base, <strong>the</strong> lateral wings being usually somewhat unsymmetrical;<br />
<strong>the</strong>), are marked by fine parallel longitudinal veins<br />
converging toward <strong>the</strong> base and anastomoslng at intervals. In<br />
size <strong>the</strong>y range from 0. 5 era. to -0.5 cm'. in length by 2 mm. to io<br />
ram. in width. Both Holliek and <strong>New</strong>berry call attention to <strong>the</strong><br />
somewhat greater length <strong>of</strong> <strong>the</strong> middle wing, whid_ is, however,<br />
far from being a constant character since some specimens fail<br />
to show it, all <strong>of</strong> <strong>the</strong> ubngs being <strong>of</strong> similar size, or <strong>the</strong> central<br />
wing may even be mucb smaller, as it is in som.e <strong>of</strong> <strong>the</strong> Alabama<br />
material, where, along with <strong>the</strong> normal forms, <strong>the</strong>re occur o<strong>the</strong>rs<br />
with all <strong>of</strong> <strong>the</strong> wings directed upward and <strong>the</strong> central one ouly<br />
about half <strong>the</strong> size o.f <strong>the</strong> laterals.<br />
<strong>The</strong> botanical relation <strong>of</strong> <strong>the</strong>se curious objects remains unknown,<br />
although <strong>the</strong>y are probably comparable to <strong>the</strong> bracts so<br />
largely developed in some <strong>of</strong> <strong>the</strong> Juglandaceae and Betulaceae,<br />
" or to certain <strong>of</strong> <strong>the</strong> winged fruits to be found among <strong>the</strong> modern<br />
Sapindacem or Dipterocarpacea:. In <strong>the</strong> abundant remains from<br />
"rottenville, <strong>State</strong>n Island; Gay I-read and Nashaquitsa, Marthas<br />
Vineyard, and Gleu Cove, Long Island, D_r.Hollick has described<br />
ano<strong>the</strong>r species, Tricalycites major* based on forms which are<br />
usually two winged and with a larger nucleus, <strong>the</strong> wings reaching<br />
a length <strong>of</strong> 4 _n. and a width <strong>of</strong> z.3 cmv _he same author has<br />
described similar but smaller remai_s from Marthas Vineyard<br />
as Calycites oboz,atus'- and still sn*aller remains from Montauk<br />
Point as Ca_¥citeg alctus a. \x,qlile perhaps from' <strong>the</strong> standpoint<br />
<strong>of</strong> <strong>the</strong> paleobotanist <strong>the</strong>se segregations are permissible or even<br />
desirable, it may be doubted if <strong>the</strong>y express real specific distinctions<br />
and not merely individual variations. T,here is certainly a<br />
suggestion in <strong>the</strong> forms from, <strong>the</strong> Tuscaloosa formation <strong>of</strong> Alabama,<br />
which occur with <strong>the</strong> normal Tricalycites papyraceor_s, that<br />
