Dozy et Мок. Bryol. Javan. t. 37).—Samoan Islands, Tutuila (Powell! п. 18); found also in Java, and a 
specimen was marked by Dickson as received from India. Stems seldom more than half an inch high, more 
frequently shorter; leaves when dry incurved, the margins involute, with no trace of the callous limb.

leaf, with section, magnified. 3. C. serratum, A. Braun, Bryol. Javan. t. 50,—Samoan Islands, Tutuila, on 
Tree-ferns (Powell! n. 47) ; also in Java.

tosus, elongatus; folia densa, a basi erecta parum latiore patentia, ligulata, planiuscula, apice subito 
contracta, obtusa, nervo crassiusculo in mucronem crassum lamina foli angusta marginatum apice 
cupuliferum producto, limbo basi angusto lamina tenui angustissimo crenulato marginato supra basin 
erectiorem obscuro extus biangulato angulis breviter serrulatis usque ad acuminis basin producto, 
cellulis hyalinis ad apicem usque partis erectioris continuatis, cellulis superioribus minutis rotundis 
obseuris; folia perichætialia conformia, apicibus vix ad thecæ cylindricæ os attingentibus, oper- 
culum subulatum ; calyptra angulis scabris.— Viti, damp places in high ground (Milne! 352, Herb. 
Hooker), Aneitum (Milne !), Samoan Islands, Tutuila (Powell! n. 25), Tahiti (American Exploring 
Expedition). 
Trisus IV. HYPOPTERYGIEÆ.—Caulis primarius repens, ramos ascendentes vel erectos inferne 
stipitiformes superne in frondem erectam vel horizontalem divisi. Folia dimorpha, majora dis- 
ticha oblique inserta asymmetrica, minora symmetrica transversim inserta. Theca in pedunculo 
exserta, peristomio perfecto vel ciliis carentibus. Calyptra dimidiata. Genus unicum. 
VI. Hypopterygium, Brid. 
The following two species are not yet represented in Viti:—1. H. oceanicum, Mitt. in Hook. Handb. 
Fl. N. Zealand, pt. 2. p. 487.—Kermandee Islands, Raoul Island, and Sunday Island (Milne and M'Gil- 
livray !), Norfolk Island (Cunningham and Dr. Thomson! Herb. Hooker) 2. Н. (Euhypopterygium) 
flaceidum (sp. nov.), Mitt. ; stipes elongatus, viridis, sparsifolius, supra in frondem flabelliformem ramosum 
divisus; folia ramea divaricata, ovali-ovata, obtuse acuta, nervo supra medium evanido margine limbo e 
cellularum seriebus tribus conflatis formato superne denticulis brevibus serrato cireumdata, cellulis ellip- 
tico-ovalibus areolata; folia stipuliformia orbiculata, nervo in mucronem excurrente.—Pacific Islands 
(collector unknown).—Stems 13 inch high. Frond 1 inch wide. Leaves yellowish-green. Very similar 
to H. Vriesii, Bryol. Javan. t. 140, but with leaves not so acute, more flaccid, and more pellucid. 
1. H. (Lopidium) struthiopteris, Brid. vol. ii. p. 716; rami erecti vel adscendentes, inferne 
substipitati, superne pennæformi-pinnati; folia majora sublanceolato-ligulata, apice latiuscula, nervo 
concolori in mucronem brevem excurrente, margine integerrima vel suberenulata basi latere infe- 
riore inflexa, cellulis parvis rotundis areolata ; folia minora parva, lanceolata.—Viti (Seemann !). 
The specimen consists only of a single stem, but it corresponds with those received from Java.
