Hooker Sp. Fil. 5 : 73, t. ,285 B. Collectio Lobbii e speciebus duabus 
similibus composita videtur, quarum T. Brooksii a T. Labrusca (teste 
icone Hookeri) paleis basalibus latioribus, fronde minore angustiore, 
integriore, obscuriore, glabra, soris plus elongatis distincta. 
Bidi, on limestone, Brooks 26a. 
Brooks sends also T. Labrusca, No. 26; plate 109 A, with the following note: 
“I can not agree that these two specimens are the same, P. Labrusca. They 
commonly occur on the limestone, and often together. They are always distinct. 
Even very young plants show the same differences in form and texture.” 
Asplenium Brooksii Copel. spec. nova. Plate XX. B. 
Stipitibus confertis, validis, brevibus (1-2 cm longis), paleis angustis 
usque ad 3.5 mm longis sparsis plerisque adpressis, vestitis; fronde ca. 
80 cm alta, 10 cm lata, rufo-viride, infra pilis minutis tematis vestita : 
vix aliter ab A. amboinense Willd. diversum. 
Bau, Sarawak, Brooks 25, 1909. 
Near A. amboinense, but larger and broader, with fewer and smaller scales 
at the base, spores (in my specimens) more spiny, and distinguished especially 
by the pubescence of fine, short hairs, borne in threes with a common base. The 
sori fall slightly short of the margin, but some-of them reach the costa. Dedicated 
to its discoverer, Mr. C. J. Brooks.
