Schimper’s herbarium there are two specimens of a moss, 
one labelled ‘* Holomitrium procerrimum Sch. Taiti’’; the other 
‘ Dicnemon giganteus Sch. Taiti. Sir Wm. Hooker dedit June,

as Leucodon rugosus by Hooker in Muse. Exot. 1, tab. xx. (1818), 
and the habitat given as “In Nova Hollandi ; 
a Dicksonio missus,”” No definite information as to the exact 
locality or the name of the collector seems ever to have been

Dienemon collected by Banks in Tahiti as D. Banksii, considered 
by the author to differ from D. rugosus in certain vegetative cha- 
racters. The description runs as follows :—* Folia caulina sequalia 
(haud rugosa) dense imbricata robustissima, late ovato-lanceolata, 
basi constricta, superne plus minus involuta, inferne margine albida, 
nervo tenui complanato in mucronulum exeunte- ercursa, infra 
nervum denticulata, e cellulis lineari-ellipticis conflatis lutescentibus, 
alaribus parenchymaticis laxis fuscescentibus planis areolata, . .. 
_ The question of the distinctness of D. Banksii from D. rugosus 
- referred to by Bescherelle in his ‘ Florule de Tahiti’ (Ann. Sci. 
rdées d’une Marge qui rappelle celle des Leucoloma, on ne saurait 
rattacher ces échantillons qu’au D, Banksii. Du reste le D. rugosus 
n’a encore été trouvé qu’a la Nouvelle Hollande ; le seul échantillon 
connu aurait été donné par Dickson 4 Turner et par celui-ci 4
