The mechanism of the dwarf male formation in the three isosporous Leucobrya
we have studied seems to be similar to that in isosporous Macro- mitria (Une
1985a). The male spore of isosporous species has the potential capacity to
develop ...

Fossil Plants: A Text-Book for Students of Botany and Geology
The strobili were isosporous and consisted of a central axis bearing verticils of
distally expanded sporophylls with sporangia, as in Equisetum. The genus
Equisetites might be included in this family, but it must be admitted that we know
next to ...

Phytography as a Fine Art
With respect to the occurrence of micro- and megaspores we may distinguish
heterosporous forms, whilst those forms having only spores of one shape are
called isosporous. S. No. 94. (cf. S. No. 79). Polarity of base and apex in spores.

Geological Survey Professional Paper
The great range in size of spores of Dicrospora is comparable to that exhibited by
spores of Calamospora S. W. & B. which is allied with some of the isosporous-
heterosporous articulate groups. However, there is no evidence, other than the ...

Genomics of Chloroplasts and Mitochondria
The mitochondrial genome of a first isosporous lycophyte (Huperzia, Yin-Long
Qiu, pers. comm. and see previous chapter) and the comparisons of hetero- and
isosporous monilophyte mtDNAs will clearly shed more light on these ...

Nuclear Cytology in Relation to Development
In the isosporous species (e.g. isos- porous ferns, horsetails), the spores give rise
to minute free-living monoecious gametophytes (prothalli). From the fertilized egg
adiploid embryo is formed, which further develops into the leafy plant ...
Evolutionary development shows a transition from isosporous to heterosporous
forms. Clubmosses probably evolved from Asteraryfon-like forms of the
Psilophytatae; there are various similarities between the two classes, especially
in the ...
Leafless or with small leaves ; sporangia terminal, not on leaves ; isosporous.
Lycopodiinae. Leaves small ; sporangia solitary on the upper surface of the
sporophyll ; isosporous or heterosporous ; spermatozoids bi-ciliate. (Orders ...

A Text-book of General Botany
The Leptosporangiatae, as in the previous division, comprise two series : A,
Isosporous ; B, Heterosporous. A. Isosporous Leptosporangiatae. The isosporous
Leptosporangiatae comprise six families : 1. Osmundaceae. This small family
forms ...
