“…This model of gametophyte development has already been cited by other authors for the genus Thelypteris (Pérez-García et al 1994). By contrast, other studies in the same genus have reported the Aspidium type as prothallial development (Pérez-García & Mendoza-Ruiz 2004;de León et al 2008;Mishra et al 2019).…”

“…The germination pattern for both species corresponds to the Vittaria type (Nayar & Kaur 1968, 1971, which is characterized by the first rhizoid and the first prothallial cell emerging perpendicularly one to each other. This is one of the most typical germination patterns in leptosporangiate ferns (Nayar & Kaur 1968, 1971 and has already been reported for other species in the family Thelypteridaceae (Huckaby & Raghavan 1981;Sen 1981;de León et al 2008;Mishra et al 2019). The process of development of the gametophyte corresponds to the Drynaria type (Nayar & Kaur 1969, 1971, in which an apical meristematic cell being differentiated after a spatulate nonmeristic thallus is formed by divisions of the anterior cell of the germ filament.…”

“…As for the sexual organs, archegonia have the typical appearance of leptosporangiate ferns (de León et al 2008). The antheridia have a distribution close to the notch, which had already been shown in other works (Tigerschiöld 1989(Tigerschiöld , 1990Mishra et al 2019). In the case of C. subpubescens, the antheridia, on the one hand, developed in gametophytes that already had archegonia, meaning that they are bisexual prothallus; on the other hand, amorphous gametophytes were observed, small with antheridia from day 45 after germination.…”

“…The morphological and sexual characters of gametophytes have been traditionally studied (Atkinson & Stokey 1964;Nayar & Kaur 1971;Atkinson 1973;Raghavan 1989), in particular in the family Thelypteridaceae, works have been made mainly on the genera Thelypteris Schmidel and Macrothelypteris (H. Itô) Ching (Atkison 1971;Tigerschiöld 1989;Watkins & Farrar 2005;de León et al 2008;Mishra et al 2019), but also from other genera of the family such as Amauropelta Kunze Pneumatopteris Nakai, Sphaerostephanos J.Sm. (Tigerschiöld 1989) Despite all these descriptive works on gametophytes in general and in the family Thelypteridaceae, the gametophytes of Amblovenatum immersum and Christella subpubescens are unknown to science.…”

The gametophytic generation of Amblovenatum immersum and Christella subpubescens (Thelypteridaceae), including spore germination, morphological development of the gametophytes, major vegetative features and reproduction strategies, was studied. For both species, the spore germination was of the Vittaria type and the developmental pattern was of the Drynaria type. Adult gametophytes were cordate and hairy, with unicellular and secretory hairs located in the margins and both the ventral and dorsal surfaces of the prothalli. C. subpubescens has another type of acicular hairs only in the margin of the prothallus. Gametangia were of the normal type described for leptosporangiate ferns. In A. immersum all the gametophytes were female. In C. subpubescens the gametophytes produced at first instance female gametangia and then became bisexual with time. Antheridiogen activity was observed in both species, suggested by the presence of small young ameristic gametophytes with antheridia surrounding well-developed female ones.

Christella kendujharensis S.K. Behera & S.K. Barik (family: Thelypteridaceae) is a critically endangered fern endemic to India. We developed its mass propagation protocol through in vitro spore culture in a liquid suspended medium for germination of gametophytes that produced sporophytes subsequently. The spores were monolete, reniform (mean length 36.49 ± 3.6 × breadth 25.67 ± 4.2 μm) to spheroidal with fimbriate and broad‐winged perispore. The maximum germination was in the Parker's and Thompson's (P&TV) medium with 0.1 mg L−1 thiamin, 0.1 mg L−1 riboflavin, 0.1 mg L−1 biotin, 0.1 mg L−1 pyridoxin, 0.5 mg L−1 nicotinic acid, 100 mg L−1 myoinositol, 0.01 mg L−1 folic acid, and 3 mg L−1 glycine. Spore germination was Vittaria type and gametophyte development was Aspidium type. The cordate gametophyte developed archegonia on the 38th day and antheridia on the 42nd day of spore sowing. Both isolate and composite cultures developed sporophytes indicating the presence of intra‐gametophytic selfing. Based on the maximum number of regenerated gametophytes, two combinations, that is, (i) 2 mg L−1 kinetin, and 0.01 mg L−1 2,4‐dichlorophenoxyacetic acid, and (ii) 0.1 mg L−1 naphthaleneacetic acid and 2 mg L−1 kinetin in P&TV media were recommended for mass propagation of C. kendujharensis.
