This is perhaps nearest to Cyathea articulata, from which it differs in 
the narrower pinnae and closer venation and sori, as well as in the paleae. 
CYATHEA KINABALUENSIS sp. nov. 
Caudice erecto haud arborescente; stipite 75 cm alto vel al- 
tiore, deorsum atro-castaneo, ad pedem paleis rufo-stramineis 
anguste linearibus ciliatis 2 ad 2.5 cm longis dense vestito, 
sursum rhachique fuscis vel castaneis glabris vel minute et spar- 
sissime squamulatis; fronde 75 cm alta vel multo altiore; pinna 
apicale aliis simile; stipitulis pinnarum 5 ad 20 mm longis; 
pinnis majoribus inferioribus usque ad 25 cm longis et 4 cm 
latis, basi rotundatis vel oblique cuneatis, apicibus acuminatis 
vel caudatis, rectis vel falcatis, praecipue apices versus serratis, 
papyraceis, glabris; venis plerisque 3-furcatis et sine venis sim- 
plicibus interpositis; soris plerisque irregulariter biseriatis, a 
costa remotis, exindusiatis.

Most nearly related to Cyathea arthropoda, from which it differs in its 
darker axes and relatively narrower pinnae with more nearly parallel sides, 
as well as in the long paleae. 
Whoever is disposed to rename some of these species in Alsophila 
should have difficulty in overlooking the fact that they are nearly related 
to Cyathea Brunonis and C. capitata, but not at all nearly so to C. 
extensa (Forst.) Swtz. 
CYATHEA TOPPINGI! sp. nov. 
Rhachi fusco-purpurea, sub lente minute furfuracea; pinnis 
stipitulatis, sterile 35 cm longa, 9 cm lata, rhachi atropurpurea, 
superne velutina, alibi glabra vel glabrescente; pinnulis brevisti- 
pitulatis, 4.5 cm longis, 1 cm latis, acuminatis, basi truncatis, 
majoribus fere 4 ad costam pinnatifidis, costis nudis atropur- 
pureis, lobis proximis, obliquis, subacutis, ca. 2.5 mm latis, 
obscure crenulatis, subcoriaceis, inferne pallidis; venis utroque 
latere ca. 3, obliquis, simplicibus; pinna fertile angustiore, pin- 
nulis 20 ad 25 mm longis, vix 5 mm latis, crenatis; soris con- 
tiguis, nudis. 
Mount Kinabalu, Gurulau Spur, Topping 1824. 
In the small group with distinct fertile and sterile fronds or pinnae; 
distinguished from Cyathea dimorpha (Christ) by having the fertile pin- 
nules less cut than the sterile; and from C. Hewittii Copel. by the much 
smaller and more numerous lobes of the sterile pinnules; much less ob- 
viously related to C. glabra than is C. Hewittii. 
CYATHEA ELLIPTICA sp. nov. 
Adsunt basis et pars apicalis frondis; rhachi deorsum atro- 
fusca, 6 mm crassa, superne piloso-velutina, ibidem et praecipue
