| Jagels and Garner observed the variation in callose deposition in the ligules of Selaginella. |
| The spores are of two kinds, as in selaginella, but the macrosporangia contain numerous macrospores. |
| Nearest to the water the primeval garden began with ferns and creeping selaginella. |
| An example of a new species he discovered on his Abacos expedition is the lycophyte Selaginella bracei Hieron. |
| Selaginella tarda differs from S. sertata in that the plants are smaller and lacking flagelliform shoots, the leaves are denticulate, and the median leaves are not peltate. |
| In the second genus, Miadesmia, the seed-bearing plant was herbaceous, and much like a recent selaginella. |
