Crataegus Marcouiana, n. sp. Plate xiv, fig. 2, xv, tigs. 1, 2. 



Leaves rather thin, elliptical, acuminate, entire or dentate from th( 

 middle upward; attenuate at base; medial nerve somewhat strong 

 secondaries few, distant, three to tive pairs, oblique, angle of divergence 

 30 degrees, subopposite, parallel, the lower suprabasilar nervilles 

 right angles to the secondaries.

 species, but some intermediate fragments show their identity, as well as 

 the form and the nervation. The leaves are comparable to those of 

 Crataegus Komerupi Heer (Arct. Fl., vii, 2, p. 13G, PI. lxvii, fig. 1) and 

 C. tenuipes Heer (ibid., PI. lxxxiit, fig. 8), as well as to those of somet 

 living species like C. arborescens, C. mexicana, C. crusgalU, etc. Thet 

 leaves vary from 5 to 8 cm long anil from 2£ to 4 cm broad, with a slenden 

 petiole l^ cm long, enlarged at the point of attachment.
