 cuneata; folia intermedia erecta, appressa; intermedia ramulorum 

 ultimorum imbricata, parallela, fere recta, obovato-oblonga, maxima

 rotundato-cuneata. Spicae brèves, ca 4 — 5 mm latae, platystichae, 

 resupinatae; sporophylla trimorpha, lateralia (antica) ascendentia, 

 lanceolata, breviter mucronulato-acuminata, plus minusve carinata

 intermedia inferiora (macrosporangiorum) ovata, valde inaequilatera, 

 breviter cuspidata, ca 31/2 mm longa, latere exteriore angustissima, 

 apicem versas sensim angustata, latere interiore latissima, apice 

 obtusa et prope cuspidem emarginata, marginibus ciliolato-denti-

 culata, maxima ca 2^/4 mm longa; macrosporae albidae vel pallide 

 flavidae, laeves; microsporae coacervatim accumulataealbido-flavidae 

 vel pallide aurantiacae, fere cerebriformes, i. e. dense tuberculato- 

 verrucosae, verrucis connatis rugas confertas flexuosas vel irre- 

 gulariter moniliformes formantibus. 



The classification of this species is not quite certain the 

 description being taken from an incomplète spécimen. Very distinct 

 by its trimorphous sporophylla, the microspores densely rugulose 

 with connected tuberculiform projections giving them a nearly 

 brain-shaped aspect— Hieronymus thinks this to be very similar 

 to S. lanceolata Warb., from Gelehes.
