Abstract. Alansmia, a new genus of grammitid ferns is described and combinations
are made for the 26 species known to belong to it. Alansmia is supported by five
morphological synapomorphies: setae present on the rhizomes, cells of the rhizome
scales turgid, both surfaces of the rhizome scales ciliate, laminae membranaceous, and
sporangial capsules setose. Other diagnostic characters include pendent fronds with
indeterminate growth, concolorous, orange to castaneous rhizome scales with ciliate
or sometimes glandular margins, hydathodes often cretaceous, and setae simple,
paired or stellate. The group also exhibits the uncommon characteristic of producing
both trilete and apparently monolete spores, sometimes on the same plant. New
combinations are made for Alansmia alfaroi, A. bradeana, A. canescens, A. concinna,
A. contacta, A. cultrata, A. dependens, A. diaphana, A. elastica, A. glandulifera, A.
heteromorpha, A. immixta, A. kirkii, A. lanigera, A. laxa, A. longa, A. monosora, A.
reclinata, A. semilunaris, A. senilis, A. smithii, A. spathulata, A. stella var. stella,
A. stella var. flava, A. turrialbae, A. variabilis, A. xanthotrichia. Lectotypifications
are made for Alansmia concina, A. variabilis, Polypodium ciliare, P. flexile, and
P. ovalescens. The genus is named in honor of pteridologist Alan R. Smith.

Polyphyly among genera of grammitid ferns has necessitated several nomenclatural innovations. The genus Galactodenia is
here described to accommodate two species that were previously placed in Terpsichore, G. delicatula and G. subscabra, and three new species
that are here described, G. pumila, G. parriseae, and G. vareschii. In recent phylogenetic studies, the two previously described species form a
clade sister to the clade of Lellingeria, Melpomene, and Stenogrammitis, and are not closely related to either Terpsichore or Alansmia, two genera
that they have been previously considered close to. Galactodenia can be diagnosed by having concolorous rhizome scales, monomorphic
fronds with non-calcareous hydathodes, and hairs that are simple and 2-celled or 1-furcate and 3-celled with large translucent clavate glands
that produce a viscid exudate. Most species of Galactodenia are found in montane forests from southern Mexico and the West Indies to Bolivia,
from 2,000\–4,000 m. One exception to this is G. pumila, which is known only from isolated granite inselbergs at 1,500 m, in southwestern
Venezuela. All five species are illustrated, and a distribution map and a key are provided.
