Hymenophyllum veronicoides C. Chr. sp. nov. 



Parva, stipite setiformi, tereti, glabro, atrofusco, 2 cm 

 longo. Lamina lanceolata, 4 cm longa, vix 1 cm basi lata, 

 glabra, fusca, tripinnatifida. Rachi sursum anguste alata. 

 Pinnis 15-jugis, deltoideis, 4 — 5 mm longis, costa alata; 

 pinnulis inferioribus subpinnatifidis, superioribus furcatis; 

 segmeulis ultimis obtusis vel leviter emarginatis, sub 1 mm 

 longis, plus minusve convolutis. Soris ad tertiam partem 

 superiorem frondis aggregatis, 3 — 4 pro pinna; iudusiis 

 duplo vel triplo quam segmente fructifère latioribus, valvis 

 rotundis. 



This uew species seems to be very distinct. The whole 

 leaf resembles strikingly a fruiting plant of some small 

 annual species of Veronica, because the large somewhat 

 inflated indusia are crowded at the upper third of the leaf 

 as are the capsules of Veronica. The narrow leafy parts of 

 the segments are rolled over the thick medial vein. The 

 dried plant is of the same characteristic brown colour as 

 H. fumarioides. 



Madagascar: Région floristique du Centre. Massif de 

 Manongarivo, vers 1400 mètres d'altitude. Bois secs. Au 

 pied des troncs dans les endroits obscurs. H. Perrier de la 

 Bâthie, n» 7775. 



Another spécimen, n" 7774, from quite the same locality 

 is no doubt belonging hère; it is in size, colour and crowded 

 sori like the type, but the lamina is narrowed downwards 

 and the leafy parts of the segments as well the wing 

 to the rachis are broader and ail rolled over the vascular 

 parts.
