NOTES AND OBSERVATIONS ON INDIAN PLANTS. 543 



The beautiful ramification of the veins, and their union, 

 from which the sorus originates in Matonia, is not alto- 

 gether peculiar to it. A.mong the genera of Polypodiacece 

 having an indusium, one remai-kable example occurs in a 

 genus as yet undescribed {Hypoderris) , which with an 

 indusium not materially different from that of Woodsia, 

 has exactly the habit of Aspidium trifoliatum ; while of 

 those genera of Polypodiacece which are without an indu- 

 sium, the same kind of vascularity is found in an extensive 

 and very natural section of Polypodium, to which Polypo- 

 dium phymatodes and the greater number of those species 

 soris saccatis belong. — Brown.
