348. Gleiehenia diearpa. — Chatham Island, W. Travers (F. Mueller). 
348. After 4. G. Jlabellata, add — 
5. G. dichotoma, Willd. Stipes zigzag, repeatedly 2-3-chotomous, 
ultimate branches bearing a pair of forked pinnae ; a pair of pinnae also arises 
from the base of the forked branches ; pinnae lanceolate, acuminate, pinna- 
tifid ; segments linear, obtuse or emarginate, glaucous below. Capsules 10- 
12, exposed. — Hook. Sp. Fil. i. 12. G. Hermanni, Br. 
Northern Island: Hot springs, Karapiti, Hochstetter ; and at Rotamahaua, J lair. A 
most abundant tropical fern all over the globe. Curiously enough, Forster (as stated in the 
Handbook) gives New Zealand as a habitat of this plant, where, however, he never saw it 
in all probability, and erroneously describes the roots as eaten. 
349. Cyathea dealbata. — Chatham Island, IF. Travers. 
349. c. medullaris. — Chatham Island, IV. Travers ((7. Cunninghamii, F. 
Muell. Veg. Chatham Island, 657). 
350. C. Cunninghamii. — Colenso assures me that this was not found at the 
Bay of Islands, but given by himself to A. Cunningham. 
351. Dicksonia squarrosa. — Chatham Island, IF. Travers. 
354. Hymenophyllum dilatatum. — Frond sometimes 24 in. long, Logan. 
354. n. crispatum. — This name should give place to H. Javanicum, 
Sprengel , which is of earlier date. 
354. H. polyantbos. — Frond sometimes 10 in. long, Logan. 
355. H. flabellatum. — Chatham Island, IF. Travers. Mr. Logan sends spe- 
cimens 9 in. long. 
355. H. feruginosum. — This is considered distinct from the Tristan d’Acunha 
plant, in Hook. Synops. Fil., and Mr. Coldnso’s name of H. Franklinianum con- 
firmed to it. I must confess my inability to distinguish it. Air. Kirk in- 
forms me that it is found at Hunua, 25 miles from Auckland. 
355. H. Lyallii. — This is referred to Trichomanes, in Hook. Synops. Fil. It 
is found at Hunua-IIuia, Auckland. — Kirk’s MSS. 
355. After H. Lyallii , add — 
16. H. ciliatum, Sioartz. Rhizome 1-2 in. long. Frond oblong, acu- 
minate, 3-pinnatifid, 2-6 in. long, 1-2 in. broad, main rachis broadly winged 
throughout, ciliated ; lower pinnae oblong or rhomboid, central part undi- 
vided. Segments numerous, spreading, linear, simple or forked. Involucres 
2-12 on a pinnule, at the apices of the segments, immersed, suborbicular ; 
valves divided halfway down, ciliated. — Hook. Synops. Fil. 63. 
Middle Island : Nelson, Travers. Closely allied to H. aruginosum. (America, Africa.) 
356. Trichomanes reniforme. — This has been discovered in Australia. 
356. t. strietum. — Mr. Baker regards this as the true common tropical T. 
rigidum, Swartz, and T. elongatura as a variety of it. 
357. T. venosum. — Chatham Island, W. Travers.
