This species is very similar to P. Sargentii Rehder, but differs in the smaller 

 and apparently paler and thinner leaves, the frequent presence of pubescence on the 

 petioles, in the peduncle (4-20 mm. long), the occasional pubescence of the pedicels, 

 the very slender cupula (6.5-10 mm. long, in P. Sargentii 5.5-7 mm. long) and in 

 the smaller and broader stone (6-8 mm. long, in P. Sargentii 9-10 mm. long). The 

 very similar P. Conradinae Koehne has precocious flowers, leaves with 9-12 pairs 

 of veins and a shorter cupula (4-5 mm. long).

It is not impossible that this species does not belong to the subsect. Sargentiella, 

 but to Ceraseidos: this cannot be decided until the leaves are known.
