 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. Among the genera of Polypodiacece having an indusium, one remarkable 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 sorts saccatis belong. — Brown.
