Mindanao, Lanao, Camp Keithley, 800 m. s. m., Clemens 112. 



Near A. contaminans Wall., but different in the numerous, dark, stout spines 

 and small frond; distinguished from A. latcbrosa Ilk., by the absence of scales 

 among the sori. 



CYATHEA Sm. 



Cyathea caudata (J. Sm.) Copeland. (Alsophila caudata J. Sm. in Hooker's 

 Journal of Botany 3 (1841) 419; Species Filicutn 9: 52.) Indusium mem- 

 branous, disappearing completely. 



Luzon, Cuming 267; Province of Benguct, Bagnio, Elmer 5867; Province 

 of Bataan, Mount Mariveles, Whitford 320, Merrill 3195, Elmer 6809, Top- 

 ping 366. 



Cuming's plant was distinguished by Hooker chiefly by the long-caudate 

 tips of the pinnules; in this respect, none of our plants are equally conspicuous, 

 thoxigh the tendency is evident. It is variable also in the serrateuess of the 

 segment*. 1 am altogether unable to distinguish the specimens with an indusium 

 from those which have lost it. 

 Cyathea christii Copeland n. sp. 



Caudiee 3-4 m. alto, 7 cm. crasso, apice basibusque stipitmn paleis 

 duris sordidis brunneis setaceis 15 mm. longis vestitis; stipitibus indu- 

 mento minuto deciduo vestitis, aculcis Bparsifl 1-2 mm. longis asperatis; 

 fronde 1.5-2 m. longa, tripinnatifida ; rhacbi infra glabrescentc subas- 

 pera, supra fusca brevi-pubescente ; pinnis innniis diminutis deflexis, 

 medialibus horizontalibus, 50 cm. longis, 12-14 cm. latis, acuminatis; 

 pinnulis 7 cm. longis, 15 mm. latis, serrato-caudatis, fere ad coatam in 

 segmentis lineari-oblongis denticulatis satis remotis plerumque obtusis 

 divisis, venis infra sparsim et minute paleaceis, aliter glabris, tenui- 

 eoriaceis, supra atro-viridibus, infra pallidis; venulis fcrtilibus furcatis, 

 sterilibus furcatis vel simplicibus ; soris costalibus ; indusiis fragilibus. 



Mindanao, Davao, Monte Apo, 1,800 m. s. m., Copeland 1141. 



A relative of C. caudata (J. Sm.) Cope!., and of C. spinulosa Wallich, more 

 delicate in form than either, and rather more pubescent. 



In the same locality is another new species distinguished by bearing large, thin 

 palm on the midribs of the pinnules. The material at hand, Dc Vote and Hoover 

 326, is not sufficient for a good description. 



TRICHOMANESSm. 



Trichomanes merrillii Copeland n. sp. 



Rhizomate erecto, valido; stipitibus confertis, 10-15 cm. altis, 1.5 nun. 

 missis, pilis rigidis atro-rubis 1-2 mm. longis vestitis; fronde 15-20 cm. 

 alta, 5-6 cm. lata, acuta, bipinnata; rhacbi tereta, pilosa ; pinnis patenti- 

 horizontalibus, 3-3.5 cm. longis, 7 mm. latis, obtusis; pinnulis acros- 

 copicis majoribus, 9 mm. longis, 5 mm. latis, in segmentis setaceis pro- 

 funda dissectis, glabris, coriaceis, atro-viridibus; urceolis supra axillas 

 segmentorum acroseopieorum pinnarum, deflexis, biangulatis, limbis 

 paullo dilatatis, receptaculis exsertis 5 mm. longis. (Tab. 1.) 



Palawan, Puerto Princesa, 500 m. s. m., Merrill 716. 



A plant with quite the aspect of T. javanicum, but much more dissected.
