Life forms: (1) Phanerophyte, (2; 3) Chamaephyte, (4) Hemicryptophyte, (5; 6) Geophyte, (7) Helophyte, (8; 9) Hydrophyte. Therophyte and epiphyte are not shown. The Raunkiær system is a system for categorizing plants using life-form categories, devised by Danish botanist Christen C. Raunkiær and later extended by various authors.
A PDF file is organized using ASCII characters, except for certain elements that may have binary content. The file starts with a header containing a magic number (as a readable string) and the version of the format, for example %PDF-1.7. The format is a subset of a COS ("Carousel" Object Structure) format. [24]
The NEXUS format also allows the storage of data that can facilitate analyses, such as sets of characters or taxa. Many popular phylogenetic programs, including PAUP*, [2] MrBayes, [3] Mesquite, [4] MacClade, [5] and SplitsTree, [6] use this format. Nexus file names typically have the extension .nxs or .nex.

Plantago lanceolata is common in Europe, including Britain. [5] It is widespread throughout the British Isles, but scarce on the most acidic soils (pH < 4.5). It is present and widespread in the Americas and Australia as an introduced species.
The formation of woody tissue is an example of secondary growth, a change in existing tissues, in contrast to primary growth that creates new tissues, such as the elongating tip of a plant shoot. The process of wood formation ( lignification ) is commonest in the spermatophytes (seed bearing plants) and has evolved independently a number of times.
