PLATE No. CCXIX, is a curious Pteris forwarded from Ceylon by Mr. T. W. Beckett. I t is, I believe, a variety of my Pt. Otaria,
and seems intermediate between Pteris otaria and Pt. crenata—it is, I believe Pt. q u a d r i-a u r ita var. ludens of Mr. Thwaites’ enumeration
(C. P. 1351 and 3060) and Mr. Thwaites suggests th at it may be a hybrid.
C. Veins uniformly reticulated, without free included veinlets.
