Glasnevin Botanic Gardens

Summer has hit Dublin with a vengeance and I am really enjoying the sunshine and long nights.....it doesn't get dark till around 9.30 or 10pm, so you can manage to fit so much more into a day.
On Monday I had an appointment to view items in the Glasnevin Botanic Gardens Herbarium which I had already identified months ago. Many herbaria simply do not have the manpower or resources to accommodate random requests to view their collections, so one has to have both the knowledge of the collection itself and the ability to work independently within that environment to gain access. Lucky for me I have some cred...haha....after this I will call myself "the seaweed whisperer" ...all will be revealed....

Like the Herbarium at TCD, Glasnevin Herbarium was furnished with gorgeous old wooden cabinets and drawers, although most of the collection itself is kept in a steel compactus. Items I had requested were waiting for me, but I was also given free range to the unincorporated material which, to my mind, holds the greater interest because it is material that is not broken up into taxa and distributed within the scientific working collection. For me, this is where I can find untold stories, mysteries and give rein to my inner supersleuth.

The Herbarium

My primary object of interest was a 19th century album of Irish seaweeds collected by William Sawers, a collecting companion of my focal collector, Charles Morrison. I have documented approximately 15 Morrison albums now, and this album would enable me to pinpoint specific collection locations and times that they collected together. Comparison of handwriting on duplicate specimens will enable me to accurately interpret an album I will be viewing during my residency at the Ulster Museum Herbarium in a few weeks time. I have planned everything down to the nth degree for this trip as it is a once in a lifetime opportunity to get the final clues needed for me to finish writing  a paper and focus on new artistic work for an exhibition next January.

Sawers Seaweed Album

Here are a few examples of Sawer's album. Incredibly, there was also a letter attached from a botanist written  in 1952 who was also trying to determine the same things I was - the differentiation between Sawers and Morrison collections! Unfortunately she has passed, but I wish I could go back in time to discuss my findings with her.

Looking familiar, same but different!

The wonderful thing about life is it always throws you up something you don't expect, and on this trip so far there have been two collections which have not had information about them on file, but which I have managed to find provenance for, or add substantially to that knowledge. One collection was at TCD, and the other here at Glasnevin.

Encounter Bay Seaweed folio

In a listing of holdings there was an item called "Encounter Bay seaweeds" - no other information.
I had asked to view it but initially thought it must be a Jessie Hussey collection. Jessie Hussey was an Australian seaweed collector of some regard in the 19th century who lived at Port Elliot in SA and collected in Encounter Bay. She was a respected collector for Von Mueller and Agardh, the Swedish phycologist.  I followed her footsteps last year, collecting at Encounter Bay, and introducing my husband's young nephew to the joys of mounting seaweeds and beach fossicking.

One of the many Plocamium specimens from Encounter Bay

This huge folio of over 90 mounted specimens was definitely not her style - there were no collection locations or dates and the specimens were very repetitive - very much an amateur collection, yet impressive in its size ( each sheet was 75cm in length)  and expensively bound. I carefully sorted through each fragile specimen. This was no easy task as many of these collections are either covered in soot or dust or, even more insidious, chemicals for preservation. This means that it is necessary to keep washing your hands at regular intervals....tiresome, time-consuming, but not negotiable. As I was sorting through the specimens, one of the pages had a name on it - the only one in the whole folio. It was Hon. G. Hawker....wow...who was that??? The Keeper and I had no idea but a quick internet search by me found that the Honorable G. Hawker had been  a prominant and well-loved politician in the SA Assembly from 1858. He arrived from the UK in 1840 with a Bachelor of Arts from Trinity College, Cambridge, and went into sheep farming. At the time of his death he was one of the oldest JP's of the district, and was one of the longest serving member of the SA Parliament in history. I didn't find any direct refernce to seaweed collecting as a hobby, but it's early days yet and I haven't finished with the Hon. Hawker yet! More sleuthing abounds........
