These most primitive seed plants can help us understand the ancient origins of how branches are formed in all land plants. At this summer’s Botany 2009 conference, I presented new studies of cycad branching. Cycads branch dichotomously: a single vascular cyl- inder becomes two equal vascular (wood) cylinders. In contrast, flow- ering plants and conifers make many branches from buds stored where the leaf meets the stem. The collections at Montgomery Botanical Center made this recent work possible.

Equisetopsida Horsetails date from the Devonian period (416 to 359 million years ago) in earth’s history where they were trees up to 110 feet in height and helped to form the coal deposits of the Carboniferous period. Only one genus has survived to modern times (Equisetum). Horsetails Horsetails (Equisetum) have jointed stems with whorls of thin narrow leaves. In the sporophyte stage, they have a sterile and fertile form. Th ey produce only one type of spore. While the gametophytes produced from the spores appear to be plentiful, the successful reproduction of the sporophyte form is low with most Horsetails reproducing vegetatively. Lycopodiopsida Lycopodiopsida includes the clubmosses (Dendrolycopodium, Diphasiastrum, Lycopodiella, Lycopodium , Spinulum) and Fir-mosses (Huperzia) Clubmosses Clubmosses are evergreen plants that produce only microspores that develop into a gametophyte capable of producing both sperm and egg cells. Club-mosses can produce the spores either in leaf axils or at the top of their stems. Th e spore capsules form in a cone-like structures (strobili) at the top of the plants.

We found 46 of the 358 described cycad species had at least one element reported to date. The only genus that was missing from the data was Microcycas. Many of the species reports contained concentrations of one to several macronutrients and no other elements. The cycad leaves contained greater nitrogen and phosphorus concentrations than the reported means for plants throughout the world. Magnesium was identified as the macronutrient that has been least studied.

  • Identification of Conifer Trees in Iowa This Publication Is Designed to Help Identify the Most Common Trees Found in Iowa
    Identification of Conifer Trees in Iowa This publication is designed to help identify the most common trees found in Iowa. It is based on vegetative characteristics including leaves, fruit, and bark. It is neither complete nor without possible oversights. Separate species are grouped by similar characteristics, mainly based on type and arrangement of leaves. These groups are; awl- or scale- like needles; single needles, flattened with rounded tips; single needles, square in cross section, with pointed tips; and needles in bundles or fasticles of two or more. Remember, vegetative character- istics are quite variable; use more than one specimen for comparison. Awl- or scale-like needles Juniperus Virginiana Eastern Red Cedar Leaves are dark green; leaves are both awl- and scale-like; cone is dark blue and berry-like. Thuja occidentalis Northern White Cedar Leaves are flattened and only of the scale type; cones have 4-6 scales; foliage is light green. Juniperus communis Common Juniper Leaves are awl shaped; cone is dark blue and berry-like. Pm-1383 | May 1996 Single needles, flattened with rounded tips Pseudotsuga menziesii Douglas Fir Needles occur on raised pegs; 3/4-11/4 inches in length; cones have 3-pointed bracts between the cone scales.

  • Scouring-Rush Horsetail Scientific Name: Equisetum Hyemale Order
    Common Name: Scouring-rush Horsetail Scientific Name: Equisetum hyemale Order: Equisetales Family: Equisetaceae Wetland Plant Status: Facultative Ecology & Description Scouring-rush horsetail is an evergreen, perennial plant that completes a growing season in two years. At maturity, scouring-rush horsetail usually averages 3 feet in height but can be range anywhere from 2 to 5 feet. It can survive in a variety of environments. One single plant can spread 6 feet in diameter. It has cylindrical stems that averages a third of an inch in diameter. Noticeably spotted are the jointed unions that are located down the plant. The stems are hollow and don’t branch off into additional stems. Also, scouring- rush horsetail has rough ridges that run longitudinal along the stem. Although not covered in leaves, tiny leaves are joined together around the stem which then forms a black or green band, or sheath at each individual joint on the stem. This plant has an enormous root system that can reach 6 feet deep and propagates in two ways: rhizomes and spores. Incredibly, due to the fact that this plant is not full of leaves, it is forced to photosynthesize through the stem rather than leaves. Habitat Scouring-rush horsetail is highly tolerant of tough conditions. It can survive and thrive in full sun or part shade and can successfully grow in a variety of soil types. It can also grow in moderate to wet soils, and can survive in up to 4 inches of water. Distribution Scouring-rush horsetail can be found throughout the United States, Eurasia, and Canada.
