Wright 1907 is peculiar in its few whorls (about 5) of small leaves, 
and long simple or subsimple nearly naked stem (2.7-3.2 dm. tall), 
but shows no technical characters of any importance, and has the 
glandular stem characteristic of P. glochidiata. The type of P. 
uncinata C. Wr. has not been seen, but from description it seems 
scarcely different from Wright 1907.
