The first column below contains seed-bearing genera from Stearn and other sources as listed, excluding those names that no longer appear in more modern works, such as Plants of the World by Maarten J. M. Christenhusz (lead author), Michael F. Fay and Mark W. Chase. [4]
This is the case for tree-based implementations, one representative being the <map> container of C++. [16] The order of enumeration is key-independent and is instead based on the order of insertion. This is the case for the "ordered dictionary" in .NET Framework, the LinkedHashMap of Java and Python. [17] [18] [19] The latter is more common.

The second name is referred to botanically as the specific epithet. Note that the two names together (not just the second name) constitute the species name. bipinnate
This method of Dictionary-Based Machine translation explores a different paradigm from systems such as LMT. An example-based machine translation system is supplied with only a "sentence-aligned bilingual corpus". [3] Using this data the translating program generates a "word-for-word bilingual dictionary" [3] which is used for further translation.
