Plantae: Divisions
1. Mosses and liverworts :Division Bryophyte (bryophytes)

-No vascular tissue and therefore no roots or stems

-restricted to moist environments because they absorb water directly through the surface of the plant

Ferns and Fern Allies:

2. Division Psilophyta: Whisk Ferns Psilotum

-green branching stems with scale like appendages and round little

sporangia (structures in which spores develop)

Moa, Psilotum nudum

3. Division Lycophyta: Club Mosses, Lycopodium 'Wawae'iole' &


-Sporangia arranged in clusters at the ends of stems

-stems are covered with small overlapping scale like leaves

4. Division Spenophyta: Horse tails Equisetum

5. Division Pterophyta: Ferns Cybotium, Hapu'u, ETC

-Largest group of nonseeding plants

-Divided leaves are called Fronds

-spores are carried on the underside of the Fronds

-Fronds arise from underground stems called Rhizomes

-Fiddle heads are young fronds as they uncurl

-abundant during past ages and contributed significantly to our coal


Gymnosperms: Seeds naked at maturity and born in cones

  1. Division Coniferophyta

-includes Pine Spruce, Redwoods, Larches, Fir

-largest and oldest trees in the world

-No native Gymnosperms in Hawaii probably because the seeds are not

salt tolerant and are not carried my birds and are too big to blow here

-supply lumber, paper pulp, turpentine, rosin

Note: Pine nuts are the seeds of the Pinyon pine

Note: Juniper berries are used to make Gin

  1. Cycadophyta: variable sized shrubs that bear seeds in cones but have a palm like appearance. EX Sago Palm.

-not native to Hawaii

  1. Ginkgophyta: Only one surviving species; Gingko biloba

-fan shaped leaves

-was propagated in a Chinese monastery and is now adays only rarely found in the wild

-tolerant to air pollution

  1. Gnetophyta: small group of gymnosperms

-Ephedra spp is a dessert shrub that produces ephedrine (antihistimine)
Angiosperms: Flowering plants Most wide spread and diverse plants on earth. Over 250,000 known species

  1. Anthophyta
