44: LYCOPODIACEAE. 2. Phyllojlossum. 



2. L. carolinianum, L. Stems often subterranean, sending up simple erect fertile 

 branches (sometimes called peduncles) ; leaves linear-lanceolate, about 3 mm. long, all 

 more or less spreading ; spikes terminating the fertile branches ; bracts spreading, ovate- 

 acuminate, minutely serrulate. 



Peaty swamps about Mount Compass and Square Waterhole. 



3. L. laterale, R. Br. Stems often subterranean, with ascending divided branches, 

 which are longer and less rigid than in the 2 preceding species ; leaves almost subulate, 

 more or less spreading, 4-6 mm. long ; spikes lateral about 1 cm. long ; bracts brownish, 

 ovate-acuminate. 



Peaty soil at Mount Lofty ; Square Waterhole ; Kangaroo Island. 



2. PHYLLOGLOSSUM, Kuntze. 



(Greek phyllon, leaf ; glossa, tongue.) 



1. Ph. Drummondii, Kunze. Dwarf plant, rising from a tuber produced during the 



previous year, with 1-3 horizontal roots close to the base of the 1-8 linear radical leaves, 



which are about 1 cm. long ; peduncle about twice as long, bearing a short cylindrical 



spike ; bracts broad, acuminate, shortly exceeding the reniform spore-cases. 



Growing in soil which is swampy in winter, National Park, Belair, and other places in 

 the Mount Lofty Range ; near Glenelg River, South-East. 



Family 10.— SELAGINELLACEAE. 



Spore-cases of 2 kinds (macrosporangia and microsporangia), solitary, sessile in the 

 same spike in the axils of the bracts ; macrosporangia containing usually 4 macrospores 

 and opening by 4 valves ; microsporangia opening by 2 valves with numerous micro- 

 spores ; spore-cases in terminal spikes ; leaves small, arranged in 4 rows, with a minute 

 ligule. 



1. SELAGINELLA, Beauv. 



(Diminutive of Selago, the Latin name of a plant believed to be Lycopodium Selago, 



the Fir Clubmoss.) 



1. S. Preissiana, Spring. A small flaccid annual, with a few erect or ascending stems, 

 simple or forked, 2-7 cm. long, leafy throughout ; leaves lanceolate, about 2 mm. long ; 

 spikes occupying the greater part of the stem or branches, the leaf-like bracts rather 

 broader than the leaves. 



Near marshes and creeks in the Mount Lofty Ranges ; Kangaroo Island ; South- East. 



S. uliginosa, Spring, has not yet been found in our State, although it grows as near to 

 it as Portland, Victoria. It is distinguished from the preceding by its perennial rhizome, 

 from which arise rigid branches with many distichous lateral branchlets and rigid leave*. 



Family 11— ISOETACEAE. 



Spore-cases brown and almost coriaceous (in our species), of 2 kinds, the macrosporangia 

 solitary at the base of the outer leaves, containing numerous macrospores, the micro- 

 sporangia solitary, at the base of the inner leaves, containing minute and still more 

 numerous microspores ; the sporangia of many species covered by a membranous velum ; 

 leaves with a minute ligule above th*> sporangium. 



1. ISOETES, L. 



(Greek isos, alike ; etos, year : because the submerged species remain the same throughout 



the year.) 



1. I. Drummondii, A. Br. Quillwort. Small plant with a short 3-lobed rootstock ; 

 leaves radical, filiform, 2-7 cm. long, perforated by 4 longitudinal air-passages, abruptly 

 dilated at base ; velum absent ; macrospores globular, tuberculate. 



In soil which is swampy in winter, but not submerged, National Park, Belair ; 

 Teatree Gully ; Victor Harbor ; Echunga. 



Division 2— SPERMATOPHYTA. 



The Spermatophytes, or Seedplants (also known as Phanerogams or Flowering Plants) 

 have complete or incomplete flowers, sometimes only consisting of stamens and ovules, 

 and effect reproduction by means of pollen-grains (microspores). These fertilise the 

 egg-cell in the embryo-sac (macrospore), which is in its turn enclosed in the nucellus of 

 the ovule (macrosporangium). The ovule ripens into a seed containing the embryo or 

 young plant.
