Ophioglossum rubellum Welw. Pusillum; totum colore 
rubro vel dilute cupreo tinetum; folia quotannis 2, altero 
plerumque sterili proferens. Lamina spathulato-obovata, ovata 
aut suborbiculata, 5—10 mm. longa, obtusa vel brevissime 
apiculata, supra opaca minutissime verruculosa, subtus laevi- 
gata, petiolo plerumque paulo breviori insidens, ecostata, 
nervo mediano tenui venarum maculis interioribus majoribus 
utrinque c. 3, exterioribus minoribus pluribus 2—3 seriatis. 
Venarum maculae majores passim divisae et ramis liberis 
divergentibus appendiculatae, maculae minores, simplices parce 
appendiculatae vel vacuae. Stomata in utraque pagina. 
Epidermidis superioris cellulae polygonales. latitudine parum 
longiores, inferioris magis elongatae et subflexuosae. Spica 
ad basin vel paulo infra basin laminae emergens, longe 
pedunculata (pedunculo cum spica 17—40 mm.) breviter 
apiculata, sporangiis utrinque 6—10. Angola. (Welw.) 
Selaginella subcordata A. Br. Surculi erecti, humiles, 
3—5 centim. alti, laxe pinnatim vel subpyramidatim ramosi, 
Caulis tenuis subflexuosus, pleurotropus, dorso aetate convexus. 
Radices tenerrimae. Folia inde a basi dimorpha, remota, 
rigidiuscula : lateralia postica, ereeto-vel horizontaliter patentia, 
late ovata, oblique subceordata, breviter ceuspidata, evidenter 
marginata et remote denticulata, margine anteriore versus 
basin breviter ciliata, axillaria lateralibus similia, sed 
paulo majora et aequaliter cordata; intermedia triplo vel 
quadruplo minora, ovata, basi subattenuata et suboblique 
inserta, in aristam aequilongam patulam excurrentia, parce 
et breviter eiliato-dentieulata. Fructificatio ignota, verisimi- 
liter platystachya. Sierra Leone. (Welw.) 
Selanınelle tenerrima A. Br. Surculi erecti humiles 
(4—6 centim. alti) gradatim decrescendo laxe ramosi, ramis 
patulis. Caulis tenerrimus flexuosus, pleurotrope rotundato- 
tetragonus, pallide. flavescens. Folia undique dimorpha et 
remota flaccida, pallide viridia, diaphana; lateralia postica, 
subhorizontaliter patula, late lanceolata et leniter extrorsum 
falcata, subinaequilatera, antice paulum latiora acuminata 
basi paullum attenuata, tenuissime marginata, denticulis in 
margine anteriore 12—15, infimis paululum elongatis, in 
margine posteriore minoribus et versus basin evanescentibus 
instructa. Folia intermedia triplo minora, lateraliter inserta, 
ovato-oblonga, basi obliqua in aristam aequilongam lateraliter 
arcuato-patulam excurrentia, carinata, utringue denticulis 
ra instructa. Spicae ramulos terminantes eosque latitu- 
ine aequantes, superficie planae, pectinatae. Bracteae hetero- 
' morphae; superficiales una cum carina late alata e basi oblique 
ovata lanceolatae, acutae, denticulatae, versus basin pauci-
