TL;DR: A review of the distribution and fossil record of LyGodium in New Zealand, South America and Antarctica suggests that the genus was widely distributed in high latitudes by the Paleocene, if the dispersed spores attributed to Cyathidites splendens are from Lygodium, and that the L. microphyllum clade appeared by the early Eocene.

TL;DR: Lygodium hazaricum a climbing fern was collected from Nandiar valley western Himalayas during 2016 and is a new contribution to the fern flora of Pakistan.
Abstract: Lygodium hazaricum a climbing fern was collected from Nandiar valley western Himalayas during 2016. The rhizome is widely creeping, dichotomously branched and densely clothed with dark brown hairs. The epidermal layer of rhizome is covered with dark brown hairs, which is sheeting at base and acute at tip. Roots arise opposite to fronds and root branches are bulbous. Rachis is with solid oval protostele. The cells of phloem are smaller than xylem cells. The sporangia are 600 μm long and 500 μm wide, globular in cross section. Sporangium is very short stalked and placed horizontally. The mature sporangium has upto 256 spores. Spores are subtriangular. Sporangium also contains few red spores. L. hazaricum is used for the treatment of diarrhea, dysentery and hepatitis. It is a new contribution to the fern flora of Pakistan.

TL;DR: This is the second report of a stem-boring pyraloid larva with a unique, cup-like modification of the anal segment in China, and the larval morphology is compared with that of the previously described S. aranea Solis and Yen.
Abstract: Siamusotima disrupta Solis, n. sp., is a stem-boring musotimine from China. It was discovered in the stems of several Lygodium Sw. species (Lygodiaceae) during exploration for biological control agents of Lygodium microphyllum (Cav.) R. Br., the Old World climbing fern. This is the second report of a stem-boring pyraloid larva with a unique, cup-like modification of the anal segment. The larval morphology of S. disrupta is compared with that of the previously described S. aranea Solis and Yen. Observations on life history are presented; the adult has not been captured in the wild.
