ADVERTISEMENTS: In this article we will discuss about:- 1. Habit and Habitat of Selaginella: Selaginella shows considerable variation in size, symmetry and morphology. Innovations (comparing with the life cycle of land plants) are in red. To work effectively with a model species, it is important to understand its morphology, anatomy, and life cycle in detail. Selaginella apoda Phylum lycophyta; aka spike moss; small ground hugging horizontal growing seedless vascular plant that is heterosporous and forms strobili and has microphyll leaves. Journal article: Schulz C, Little DP, Stevenson DW, Bauer D, Moloney C, Stützel T: An overview of the morphology, anatomy, and life cycle of a new model species – the lycophyte Selaginella apoda (L.) Spring. spores are not as flammable as club mosses such as diphasiastrum. It grows in the form of dense soddy pillows, much like moss. Mostly they are herbaceous perennials, however, a few are annu­als (Selaginella pygmaea). Points of special note (for evolution toward land plants) 1. All three megaspores germinate into female gametophytes without leaving sporangium. Figure \(\PageIndex{5}\) Megasporangium of the meadow spike-moss, Selaginella apoda (from Lyon, 1901). Figure \(\PageIndex{6}\) Life cycle of heterosporic plant. In the case of S. apoda, the gametophytes grow quickly and have high fertilization success in warm nutrient enriched water.
