The fronds of young ])lant,s are simple, a gi’adual cliange to tlie ])innate form 
occurring long before maturity. So fai’ as “(li/mnoc/ramiue ? (t^i/)>gra})}me f) suh- 
trifoliafa Hooker" in Sj). Fil., 5: 152, Plate 2118, ever was described, it is indis- 
tinguisliable from this Hieiiochlaena. Tlie most similar species is Loaiariopsifi 
spcclahilis ^lett., of which the fertile piumie are described as narrowly linear.

The fronds of this plant, both the sterile and the fertile, have altogether the 
aspect of those of 8icnoclil(icna, and the ahsence of tubercles on the liases of 
the stipes helps to conceal its real aliinity. However, the oblique aniinlns and 
the insertion of the sporangia establish its place beyond donlit.
