Comments:
The Sadleria along the ridges of upper East Maui’s northern face have characteristics that encompass both S. pallida and S. cyatheoides:
S. pallida - They have some stiff, bicolorous scales which are pointed with dark midribs and tan margins like S. pallida
Their basiscopic basal pinna segments often overlap rachis,
They have the pinnae shape and number of ultimate segments per pinnae (usually less than 30) that indicate S. pallida
S. cyatheoides – scales can sometimes be 1-colored like S. cyatheoides and taper to long hairlike tips, but are rarely torn.
They do not have the greater number of ultimate segments (35–60) that would indicate S. cyatheoides –yet they often have obscured veins when viewing abaxial surface.
