# List of botanists by author abbreviation (H)

This is an incomplete list of botanists by their author abbreviation, which is designed for citation with the botanical names or works that they have published. This list follows that established by Brummitt & Powell (1992). Use of that list is recommended by Rec. 46A Note 1 of the International Code of Nomenclature for algae, fungi, and plants. The list is kept up to date online at The International Plant Names Index and Index Fungorum.
In some cases an "author abbreviation" consists of a full surname, while in other cases the surname is abbreviated and/or accompanied by one or more initials. There is no space between the initials and the surname (or its abbreviation).

#### Order of entries

The list here is maintained strictly in order of the alphabetic characters in the abbreviation; thus "A.B.Jacks." appears under "A" not "J", and is located as if the characters were "ABJACKS". Capitalization is ignored as are all non-alphabetic characters such as "." and space. Diacritical marks are also ignored, so that, e.g., "ü" is treated as if it were "u".

#### Navigation

Because of its length, the list is split across separate pages. All alphabetic sections can be accessed from the short table of contents; the vertical bars show the page divisions. Searching will only find an entry within a page.

## A–G

| Contents: | A | B | C | D | E F | G | H | I J | K L | M | N O | P | Q R | S | T U V | W X Y Z |
To find entries for A–G, use the table of contents above.
