THE OCCURRENCE 
OF THE GENUS TINGIA IN TEXAS 
BY 
WiuuiamM C. Darran 
THE GENUS TINGIA is one of the unusual late Paleo- 
zoic plant-concepts which was formerly referred to the 
cycads, but is now considered as being a pteridophytie al- 
liance belonging to the Noeggerathiales. Hitherto the 
genus Tingia has been found only in China and Korea. 
In the course of the past four years the Department 
of Vertebrate Paleontology of the Museum of Compara- 
tive Zodlogy of Harvard University has sent expeditions 
to ‘Texas and New Mexico in quest of Permocarbonifer- 
ous vertebrates. During field work, representative col- 
lections of fossil plants were gathered in more than thirty 
localities. Among these collections, transmitted to the 
Botanical Museum for study,is a remarkable florule from 
Brazos River, Baylor County, Texas, which contains 
rather lush plants such as are believed to have lived in 
more or less moist situations. Prominent among these 
plants is 72ngva, which is represented by two new species. 
Tingia was described by Halle in 1925’, but in 1927° 
he published an emended description. ‘The emended de- 
scription is as follows: 
Tincia Halle Paleontologica Sinica ser. A. vol. 2. p.
