Dicotyledon plantlet Young castor oil plant showing its prominent two embryonic leaves (), which differ from the adult leaves. The dicotyledons, also known as dicots (or, more rarely, dicotyls), [2] are one of the two groups into which all the flowering plants (angiosperms) were formerly divided.
The Major Vegetation Subgroups were defined for the purposes of finer scale mapping and regional analyses. Version 6.0 contains 85 subgroups. In version 3.1 (approximately 2007), the Major Vegetation Subgroups were: Cool temperate rainforest; Tropical or sub-tropical rainforest

Maize (Zea mays, Poaceae) is the most widely cultivated C 4 plant.[1]In botany, C 4 carbon fixation is one of three known methods of photosynthesis used by plants. C 4 plants increase their photosynthetic efficiency by reducing or suppressing photorespiration, which mainly occurs under low atmospheric CO 2 concentration, high light, high temperature, drought, and salinity.
The Archaeplastida (or kingdom Plantae sensu lato "in a broad sense"; pronounced / ɑːr k ɪ ˈ p l æ s t ɪ d ə /) are a major group of eukaryotes, comprising the photoautotrophic red algae (Rhodophyta), green algae, land plants, and the minor group glaucophytes. [6]

The plant morphologist goes further, and discovers that the spines of cactus also share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany.
The family Euphorbiaceae is the fifth-largest flowering plant family [8] and has about 7,500 species [9] organised into 300 genera, [8] 37 tribes, and three subfamilies: Acalyphoideae, [8] Crotonoideae and Euphorbioideae. [10]
