STEREODONTEAE 
_Ectropothecium singapurense Dixon sp. nov. 
Dioicum. E robustioribus generis, habitu E. bwuitenzorgii 
et E. Dixoni Fleisch. simile; caules elongati, densissime pinnatim 
ramosi, ramis 5-7 mm. longis, crassiusculis, haud complanaiis. 
Folia confertissima, fortiter falcata vel hamata, magna, circa 2 
mm. longa, ad basin I mm. fere lata, leniter plicata; e basi lata 
subdeltoidea in acumen subulatum falcatum subintegrum vel 
tenuiter denticulatum angustata, margine prope apicem plerum- 
que leniter anguste reflexo; ecostata. Cellulae pro folii magni- 
tudine parvae, breviusculae, angustissimae, basin versus paullo 
latiores, infimae tantum hyalinae, tenues, aias decurrentes con- 
spicuas, majusculas instruentes.

One of a group of closely allied species, differing, however,

much longer, smooth cells, and more strongly toothed leaves. 
E. goliathense Fleisch. from New Guinea has longer branches 
and much larger cells. E£. —— differs entirely in the 
basal areolation.
