Pig. 5. Publications in plant systematics. "Regional" are publication on areas like Europe, tropical Asia. Australia, "bocal" means a coverage of e.g. the Netherlands, Java, i< ifornia. Main groups are Algae, Mosses, Vascular plants, Angiosperms, etc. Small groups are orders, families, genera. Transitions between the types of publication are not sharp. 

Our m.ajor food, fiber, wood and ornamental plants belong to two main classes - the gymnosperms, represented mainly by the narrow-leaved, evergreen trees and angiosperms, usually broad-leaved, flowering plants. Angiosperms are divided into two subclasses the monocotyledons, which have an embryo with one cotyledon, and the dicotyledons, which have an embryo with two cotyledons. Dicots or C3 plants have different photosynthetic pathways as contrasted with monocots or C4 plants. We are utilizing a common monocot, corn, and two dicots, bean and hibiscus. 

And so on. The list is endless. Examine each case. Find that fishes nest within, or among, invertebrates humans, within apes animals, within plants angiosperms, within gymno-sperms and Greeks, alas, within barbarians. 

Unidentified Stimulators. Growth-inhibitory materials in, or secreted by, plants have for the most part been emphasized in this paper. However, root secretions of many plants also contain constituents required for the germination of seeds of angiospermous root parasites (Striga, Orobanche, Alectra, and Sopubia genera). This phenomenon has been reviewed by Brown (17). Striga asiatica was identified for the first time in the western hemisphere in 1956 in two... 

Aquaporins are central players in mammalian physiology, but are also important in microorganisms and plants. The number of AQPs in plants is quite high angiosperms species, for example, express approximately 35 different AQPs divided into four families on the basis of their sequence. Moreover, plant AQPs might be considered multifunctional channels for their different transport properties.

The two types of wood differ, however, in their nature and structure. The main structural characteristic of the hardwoods (which are botanically known as angiosperms, plants that flower to pollinate for seed reproduction) is that in their trunks or branches, the volume of wood taken up by dead cells, varies greatly, although it makes up an average of about 50% of the total volume. In softwoods (from the botanical group gymnosperms, which do not have flowers but use cones for seed reproduction) the dead cells are much more elongated and fibrous than in hardwoods, and the volume taken up by dead cells may represent over 90% of the total volume of the wood.
