P. contortum, Chr. in sched. 
Quoad staturam ut in a, sed frondibus plerumque sparsis, 
saepe tenuioribus, distincte et breviter stipitatis, in sicco 
admodum revolutis et irregulariter contortis. 
A form, when dry, becoming extraordinarily contorted, 
otherwise same as a. Christ is inclined to separate this form 
as a distinct species on account of the contorted condition and 
the cuspidate apex of the frond. He places the present plant 
between the type form of P. lineare and P. Lewisti, but what 
he takes for P. Lewisii Bak. is, in fact, P. involutum Bak. As I 
have pointed out above, the typical form of P. lineare, and also its 
varr. ussuriense and loriforme (v. infra), as well as P. nudum and 
other persistent species, roll up their fronds when the atmo- 
sphere becomes very dry. If specimens are collected and 
pressed in this condition, they all will appear exactly like Christ’s 
contortum. The only difference of the contortum from other 
forms of P. lineare is, so far as I can decide from the herbarium 
material, that the frond is thinner in texture, more or less 
scattered on the rhizome, distinctly stipitate, and shows a 
stronger tendency to roll up than the others. It would be more 
‘natural to regard this plant as a mere form of P. lineare a.
