…#1: Triceratium forresterii

“…before his eyes someone reads a book that,
as his later bibliographical researches prove, does not exist…”

Specimens are like books. Some are plentiful, others rare. Others, still, disappear…maybe they never existed at all.

Frederick Samuel Charles Reed died on the 25th March 1995 in Christchurch, Canterbury, New Zealand, 11 days after his 86th birthday. Reed developed an early interest in fossil diatoms but never published much on this activity.

Late in his life (in 1991, when he was 82!) he produced an atlas of diatoms for the New Zealand Geological Survey publication ‘The Oamaru Diatomite’. His atlas was a series of images of diatom valves: 279 in all, 27 of them attributed to species in the genus Triceratium.

Missing from those 27 names was Triceratium forresterii. An odd omission, as Reed had named that species himself in an extraordinarily brief one page note in the Proceedings of the Royal Society of New Zealand for 1947 (his account was delivered to that society on October 2nd, 1946). He didn’t mention Triceratium forresterii in his 1958 summary of the diatoms of Oamaru published in The Microscope either. That’s surprising too. After all, most of us have a certain amount of pride in discovering something new.

“Triceratium forresterii Reed x 35”

Unbeknownst to Reed, when he was assembling the details for his Oamaru atlas another two were occupied with a similar task. Desikachary and Sreelatha were preparing their own account of the diatoms of Oamaru, which ended up a massive 330 page book with 145 plates having more images than is easy to calculate. And they did include a reference to Reed’s Triceratium forresterii. They noticed a problem with the name: Jean Clodius [Joannes Albert] Tempère (1847—1926) had beaten Reed to it. Back in 1890, for a few specimens also found in the Oamaru (Williams Bluff) deposits, Tempère gave a completely different species the name Triceratium forresterii. To solve the problem of having two species with the same name, Desikachary and Sreelatha simply gave Reed’s Triceratium forresterii a new name. The diatom Reed named was to bear his own name, poetic justice of sorts: it became Tricertium reedi. But what did Desikachary and Sreelatha make of Reed’s diatom, what did they think it to be? They didn’t; they couldn’t tell: “…this taxon has not been recorded in the present investigation” (Desikachary and Sreelatha 1989, p. 264). They didn’t find it so they simply reproduced Reed’s original drawing (Desikachary and Sreelatha 1989, pl. 143, fig. 9) and left it at that.

Hunting for examples of Reed’s Triceratium forresterii, his own Tricertium reedi, has not been fruitful. None seem to be present in the Natural History Museum’s collection, which is a bit of a surprise, but two specimens emerged from elsewhere. The first, the most significant, come from the New Zealand collection Reed left, the type – the original – specimen (CHR 617491: Allan Herbarium, Landcare Research, New Zealand; as noted above, Reed delivered his report October 2nd, 1946; the slide is dated 17th August 1946); the other is in the California Academy of Sciences diatom collection, a specimen from the Seychelles, from DODO expedition dredgings. Now, Oamaru and the Seychelles – geographically, not exactly neighbours. Reed’s Triceratium forresterii is obviously not a Triceratium in any accepted sense. So: What is it? Well, other might have ideas on that. Are there more species related to whatever Reed’s Triceratium forresterii is? No doubt. Where did they come from? Well, that would be nice to know. But, even so, it does exist…

As it happens, a search for Tempère’s Triceratium forresterii is equally mystifying, yielding few good examples. In Albert Mann’s account of the Marine diatoms of the Philippines (more on that later), he offers a description of another new species, one of his own Biddulphia cycloides. Here Mann mentions Triceratium forresterii (he attributes the name to Pantocsek rather than Tempère but corrects this minor error in the errata). Triceratium forresterii, Biddulphia cycloides, round and round it goes…until the next time…


Sue Gibb (CHR), Sarah Mansfield (CAS) and Jean DeMouthe (CAS) made this possible.

To Begin...

“…a cat that walks by himself,
tenaciously unhousebroken and very unsafe for children…”

“What would Goethe say to the view from this window,
the wintry, ill-lit street,
he with his recurring pleasures, fruits, and flowers?”

Why? Why do this? The fact that there are puzzles and connections, and connections between puzzles, and puzzles between connections, some starting in silence – from a whisper to a scream (“the power of persuasion is no match for anticipation”) – others deafeningly silent.

Inspiration: Thomas Radcliffe Comber (1837—1902). I’ve come across his work a few times now in connection with my studies on diatoms, the unicellular photosynthetic organisms I’ve devoted quite a bit of my life to. I was asked a question about three names of diatom species that Thomas Comber was supposed to have been responsible for, to have created, bought into being: Neidium dubitatum, Neidium iridis var. rhodana and Nitzschia moissacensis. The electronic online Catalogue of Diatom Names at the California Academy of Sciences, presumably following the earlier printed version by Sam VanLandingham, cites as the source of these three names the publication ‘Comber 1901’. Comber published two items in 1901: a contribution to the Catalogue of African Plants Collected by Dr. Friedrich Welwitsch in 1853-1861; and a contribution to the Fauna, flora & geology of the Clyde area; both are,more or less, lists of diatom species, just the names and a few details. Neither of these publications includes any of the three names above. The names have all but vanished. A puzzle.

At the same time I was looking into Comber’s lost names, I was reading Anatole Broyard’s Kafka was the Rage, his memoir of 1940s Greenwich Village, New York City. It has been said that Coleman Silk, the ‘hero’ of Philip Roth’s novel The Human Stain, was based upon Broyard. This is not so. Broyard’s Kafka was the Rage is entertaining for a number of reasons but there was this story, a tale of the opening of a bottle of wine. The bottle resisted opening and, after several attempts, with a final hefty yank of the corkscrew:

“I pulled very gradually, gently at first, then more strongly. Nothing happened. The cork didn’t budge. I couldn’t imagine why not—it wasn’t as if this was an ancient bottle of wine that had been sealed by time itself. To get a better purchase, I put the bottle on the floor between my feet.

What came next still seems incredible to me. Sometimes I think it didn’t actually happen, that my memory is playing tricks. But it did happen: Before my eyes, I saw the corkscrew slowly emerge from the cork. It didn’t break off; the cork didn’t crumble. The screw simply straightened out, so that I was holding in my hand something that resembled an ice pick.”

Can this be true? Could it really have happened? A different kind of puzzle – maybe one too odd and ancient to investigate?
Is there any connection between Anatole Broyard and Thomas Comber, 1940s Greenwich Village and the study of diatoms? Do you see the connection(s)? You will. In time. But for now, the connection is simple: Me.

What will follow in subsequent posts is a series of vignettes, a series of essays centred around a particular diatom, with connections and puzzles, some simple, others not, some puzzles solved, others not, some puzzles to which I really should know the solution, others no one can hope to…or maybe…

I can’t explain Broyard’s corkscrew but I can help with Comber’s names:

A quick look at an earlier printed catalogue of diatom names, the one published by Frederick William Mills during the 1930s, An index to the genera and species of the Diatomaceae and their synonyms, provides the solution. Mills included the three lost Comber names – Neidium dubitatum, Neidium iridis var. rhodana and Nitzschia moissacensis but attributed them to someone called ‘Combere’. There is no such person. ‘Combere’ was subsequently interpreted as an error for Thomas Comber, when in fact it was an error for an entirely different person: Joseph Comère (1854—1932), a pharmacist and phycologist who occasionally dabbled in diatom studies. Hunting around I eventually found this article by Comère: ‘Documents pour l’étude des diatomées d’eau douce’, published in a commemorative issue of Nuova Notarisia, celebrating their 40 years of publishing (1886—1925). Here is where the names can be found:

Neidium dubitatum (Héribaud) Comère and Neidium iridis var. rhodana (Brun) Comère on page 69; Nitzschia moissacensis (Heribaud) Comère on page 87.

A fictitious person – ‘Combere’ – becomes a real person – Comber, but the wrong real person; who becomes the right real person: Comère. All with the switch of a b for an e. Comber – the real person – will return shortly.

There will be (there are) items of relevance for the future scattered around (“the power of persuasion is no match for anticipation”)…Easter eggs as silica valves: “Only Connect” (E. M. Forster, 1910). More clues that (than) you need…

The solution to the three lost names was easy to solve…the rest, what follows, well…let’s see…
