Despite the importance of species discovery, the processes including collecting, recognizing, and describing new species are poorly understood. Data are presented for flowering plants, measuring quantitatively the lag between the date a specimen of a new species was collected for the first time and when it was subsequently described and published. The data from our sample of new species published between 1970 and 2010 show that only 16% were described within five years of being collected for… 

Figures from this paper

Author inflation masks global capacity for species discovery in flowering plants.
TLDR
A comprehensive dataset from The International Plant Names Index of new species of flowering plant published between 1970 and 2011 shows that, on average, 1855 new species have been described annually since 1970.
A revision of Canarium L. (Burseraceae) in Madagascar
TLDR
The number of accepted species in the genus Canarium is increased by 33% worldwide and Madagascar is established as a primary center of diversity for the genus.
Assessing the Relevance of Herbarium Collections as Tools for Conservation Biology
TLDR
This paper assesses the potential of herbarium collections on conservation biology, by providing exemplary studies that use herbaria specimens, grouped into four categories: based on occurrence data, such as studies about plant extinction or introduction, or those focused on modelling their ecological niche.
8 The Role of Herbaria and Culture Collections
TLDR
The role of fungal herbaria and culture collections as sources of reference material for scientists studying fungal biology and systematics is explained and the main principles of cryopreservation and freeze drying are explained.
A plea for modern botanical collections to include DNA-friendly material.
Three Edaphic-Endemic Ceanothus (Rhamnaceae) New to Science
TLDR
Three new taxa of Ceanothus are described, two initially noted among existing collections, and another discovered during botanical exploration in San Diego County, which are edaphic micro-endemics found only in the southern California Floristic Province, California.
The number of known plants species in the world and its annual increase
TLDR
Phytotaxa is currently contributing more than a quarter of the ca 2000 species that are described every year, showing that it has become a major contributor to the dissemination of new species discovery, but the rate of discovery is slowing down.
21 years of shelf life between discovery and description of new species
Dr. Roberto Miguel Klein Herbarium (FURB), Blumenau, Southern Brazil
TLDR
The collection of the FURB herbarium, its collection area and type specimens, as well as its projects and contributions to the flora of the Subtropical Atlantic Forest are presented.
Influence of biological and social-historical variables on the time taken to describe an angiosperm.
TLDR
Results support four recommendations to hasten discovery of new species including preferential collecting of plants below 2.6 m, at least in the Cerrado; access to undetermined material in herbaria; fieldwork in areas where narrow-endemic species occur; and fieldwork by knowledgeable botanists followed by descriptive activity by the same.

Discovering the plant world
The last fifty years have been a time of accelerated plant collection, especially in the tropics. However, this is a race against time since the destruction of natural habitats has also increased
Two new species of Licania (Chrysobalanaceae)
TLDR
L. corniculata is unique in Chrysobalanaceae in the pair of stalked glands near the lamina base and is described from near Pucallpa in Peru where it was found in a transect carried out in the Sira mountains.
Taxonomic Novelties from North America north of Mexico: A 20-Year Vascular Plant Diversity Baseline
A survey of the literature and the Gray Herbarium Card and Kew indices was performed to determine the number of taxa new to science published in North America north of Mexico from 1975 through 1994.
NEW SPECIES AND NOTES ON NEOTROPICAL CHRYSOBALANACEAE
TLDR
Six new species of Neotropical Chrysobalanaceae are described, from five different countries, which range collectively from Honduras to Bolivia and Brazil.
The taxonomy and biology of Stenosiphonium Nees (Acanthaceae)
TLDR
There is evidence to suggest that all three species of Stenosiphonium are plietesial which may explain the paucity of herbarium collections of both S. setosum and S. wightii.
How many species of flowering plants are there?
TLDR
A model is applied that explicitly incorporates taxonomic effort over time to estimate the number of as-yet-unknown species, and asks taxonomic experts their opinions on how many species are likely to be missing, on a family-by-family basis.
New and reassessed species of Strobilanthes (Acanthaceae) in the flora of China
TLDR
Several problems in Strobilanthes Blume (Acanthaceae: Ruelliae) are clarified as a result of collaboration between Chinese and western botanists and new combinations are made for four species as the authors recognize only a single genus, St Robilanthes within the Strobilanthinae as defined by Bremekamp.

Summary. The species of Strobilanthes from East Asia with a paniculate inflorescence form a readily identifiable cluster of species, which reaches its greatest diversity on the Indonesian Island of
New genera and species of Chrysobalanaceae from Malesia and Oceania
TLDR
Two new genera of Chrysobalanaceae are described; both are quite as distinct as others of the family and have been overlooked by undue emphasis placed on the single character of a bilocular ovary.
New Taxa and Notes on Neotropical Chrysobalanaceae
TLDR
Seven new species and one new subspecies of Neotropical Chrysobalanaceae are described and the first collection this century of Couepia bondarii Prance is reported; it is the first to have a precise locality.
