544 FILICES. [ Gleichenia. 
1. G, longissima, Blume, Fil. Javan. p-250, — Stipes (once or repeatedly ?) 
forking, the last branches bearing a pair of bipinnate pinnae, the thick 
bud between them densely, and the plano-convex rhachides iit es 
covered with stiff, black, ovate, pubescent scales 1‘‘ long and cor ; the 
tender tips of the pinnae tomentose with a pale- brown eI i 
Pinnae subcoriaceous, glaucous underneath, oblong, 2—4 ft., broadest 
about the middle, Pinnules 40—50 on a are: fina 6—9' X 1/2—2', 
subsessile or shortly stipitate, with an even-sided ence base, acuminate, 
eeply pinnatifid, to the rhachis near the base. Segments linear, 1—1}/2'. 
broad, obtuse, the lowest pair longest and often reflexed over the rhachisi 
Veins distinct, almost vertical, simple, or forking near the base. Sor, 
dorsal on the anterior branch or at the fork, often one to each vein, each 
of 4 or 3 capsules. — Synops. Fil. p. 12. — . glauca, Hook. Sp. Fil. I, 4. 
— Mertensia glauca, Brack. — M. pinnata, Kze. — G. excelsa; J. Sm. 
8. — Lowest segments again pectinate. — Mertensia glabra, Brack. 
. — Mr. Baldwin has sent a specimen in which the stipes, 10’ loug and 
broken at the end (without terminal bud), exhibits 3 pairs of opposite 
rondose branches or pinnae which are much shorter than in «, only 
15‘ long, the longest pinnules 4’ X 1/2’. The stipes has sharp edges, and 
a very shallow sulcus on the flat ventral side. 
At elevations of 2000 — 4000 ft. _here and there on all islands. The species is spread 
d Is 
ur fern to be distinct from the Chinese and ese ei relying oun on the absence 
of scales and tomentum in the latter, and retains for it Kunze’s specific name G. pinnata. 
2. G. Hawaiiensis (Owhyhensis), Hook. Sp. Fil. I, 9. — Stipes spets 
compressed, and margined with two lines of small scales, the frondo 
portion 3 or 4 times dichotomous at rather acute angles and in all pon 
sions pectinately pinnatifid down to the rhachis. A bud in each fork, 
covered with small (1'/2—2”) faleate, acute, dark, ciliate scales. Last 
so the rhachis, chaffy with laciniate ferruginous scalelets. Veins vertical, 
with 2 or 3 branches. Sori on a raised punctiform receptacle, copious 
and close, with 3—6 i in each, but often the capsules irregularly 
scattered. Annulus indistinct. Spores compressed. — Synops. Fil. p. 14. 
ertensia Hawaiiensis, Br ack. — In two of my specimens the bud of 
the first dichotomy has developed into a naked rhachis of 6 and 12 inches, 
which bears at its end an intermediate forking frond. 
At elevations of 3000—6000 ft., but rare: Hawaii! Mauna ay Pach Eeka; Molo- 
kai! Pelekunu; Oahu! Kaala ‘and Konahuanui; Kauai! Hal . th 
Hawaiian Islands , but near G@. flageliaria, Spreng. » Which preter from southern 
Pol through Malaysia to Madagascar.
