Heterophyllum, Monostelicae, a^ Caulescentes.— A spécimen from 

 Amboyna, cultivated in the Buitenzorg Gardens, agrées very well 

 with Cesati's diagnosis.- It differs from S. caulescens Simng 

 principally by its larger shoots, hairy stems, more decompound 

 fronds and smaller leaves. In the numerous spikes examined 

 I could not find any trace of a macrosporangium..— The spécifie 

 name is transferred because of the earlier S. minutifolia Spring,
