View the The C.B. Trinius Herbarium Catalog (in pdf format).

The C. B. Trinius Gramineae Herbarium (LE) is a historically important collection containing some 8,000 sheets including more than 1,200 types specimens. This catalogue lists each sheet in the Trinius (1778-1844) herbarium. The sheets are listed in the order in which we found them in May of 1994. The preserved order of tribes, genera and species is essentially that of Trinius himself, although over the years a few specimens have been added or moved, and perhaps some removed. Each line begins with the name of the species on the folder in which the specimen is located. The names on the folders (often in Trinius' hand) apparently correspond to taxa recognized by Trinius, and the folders contain specimens, often types, which he considered elements of those taxa. The folder name is followed by a left bracket and the presumed (by us) correct author of that species as determined by cross-checking in Index to Grass Species (Chase & Niles, 1962). The number after the first colon represents the file folder number, followed by a period, the sequential sheet number within the folder, and a second colon. Each sheet has been numbered so that the order may be retained.

The whole herbarium has been photographed by the International Documentation Company (IDC), and our numbers will be visible in each photograph and indexed with the microfiche numbers. Following the numbers are notes on each specimen's identification, origin, type status, etc. All specimens were checked in Trinius's original publications and Index to Grass Species (ibid.) to see if they were part of the original collection of the species named on the folder. If a specimen was of a type of a second taxon, presumably placed in synonymy by Trinius, that taxon is named here along with the abbreviation for the kind of type. Identifying types is relatively straight forward for some taxa, but not so for many others. We did not attempt to check all specimens for type status, except as they corresponded to the name on the folder or other Trinius names within. Any further checking was dependent on our individual dispositions for (or success in) tracking down a name or type. Thus, there are likely to be many non-Trinius types still hidden in the collection.

Inserted names of Soreng, Annable, and Peterson bracketing series of names in the list of taxa (beginning and end), are the names of the persons who examined that series of folders. If there was more than one specimen on a sheet, then these were lettered on the sheet only if this order was important for our record keeping. Small figures and full illustrations were common in the collection, and are often the preparatory drawings for published plates. The specimens from which they were drawn are in many cases also present in the collection and many were specifically annotated as "mihi" by Trinius. We generally accepted such specimens as Holotypes.

Many thanks are due the curators of LE, especially Dmitry Geltman for technical assistance and support, and Andrej Bobrov for insights into the history, calligraphy, and secondary literature needed to interpret the collection, and to the James Smithson Society for funding of the larger project of which this was a part. Any errors, perceived or otherwise, are ours.
