CHARACTERS OF TRIBES AND GENERA. 



Grevelle, t. 62. In some Fijian specimens the sori are 

 scattered over the disk, being- round or oval, and compital 

 on the anastomoses of the veins, which may be considered 

 an abnormal condition consequent on local influences. 



Sp. T. blechnoides, Sw. (T. pteroides, ScU. Fil., t. 6, B) 

 T. obtusa, Hook. Ic. PL t. 994. 



OBS. This is described as having fronds only 1| to 2 

 inches long, and is probably only a young state of T. blech- 

 noides. They are natives of Borneo, Malay, Philippine and 

 Fiji islands. 



68. ANTROPHYUM, Kaulf. (1824). 



Hook. Sp. Fil. ; Hemionitis sp., Linn, and auct. 

 Polytoenium, Desv. 



Vernation uniserial, sarmentum, short, squamose. Fronds 

 contiguous csespitose, simple, linear-lanceolate, or oblong- 

 elliptical, or subrotund, smooth, coriaceous, with or without 

 a defined mid-rib. Veins uniform, reticulated. Receptacles 

 discal, immersed, forming grooves in which the sporangia 

 are seated. Sori reticulated or interrupted. 



Type. AntropJiijum plantagineum, Kaulf. 



Illust. Hook, and Bauer. Gen. Fil., 1. 109 A. ; Moore Ind. 

 Fil., p. 16, A., 44, A., 45, A. ; J. Sm. Ferns, Brit, and 

 For., fig. 55 ; Hook. Syn. Fil., t. 6, fig. 55. 



OBS. The general aspect and mode of growth indicates 

 the affinity of this genus to be with Vittaria, from which 

 it is technically distinguished by its reticulate venation. 

 Representatives of this genus are widely distributed 

 throughout the tropics, being found in the islands of the 

 Pacific and Indian Oceans, the continent of Asia, the West 

 Indian Islands, Tropical America and Mauritius, and have 

 also lately been found in West Tropical Africa.
