Rev Nicholas J. Halpin (1790-1850)
By the year 1818, a total of twenty-five wild plants had been recorded in Co. Cavan. The next series, a major contribution, was again in the form of
annotations on a working flora. At this time [ca. 1825], James T. Mackay
was collecting records for Flora Hibernica (1836). It is likely that he sent
copies of his Catalogue of the indigenous plants found in Ireland (1825) to active amateur botanists throughout Ireland, seeking their help by annotating the copies with new records and returning them to him to incorporate the results in his new flora.
One of the recipients was Rev Nicholas J. Halpin, of Oldcastle, Co Meath (Reilly, 1995). Fortunately his annotated copy, the only one known to exist, was found in the library of the National Botanic Gardens, Dublin (Nelson pers. comm.). It contains one hundred and ninety one records from thirteen Irish counties, including fifty-eight from Cavan. Nine were first county records, including Neottia nidus-avis, found by Joseph Archibald, Lord Farnham’s gardener. Some were published in Flora Hibernica (1836).
Halpin was born in Portarlington in 1790. After a successful academic
career at Trinity College, Dublin, he took Holy Orders and was given the
curacy of Oldcastle, Co. Meath, near the county border with Cavan. He
explored the rich enclosed grounds of Farnham and other demesnes north
of Cavan town, visited friends at Mount Nugent and his brother Charles, a
medical doctor and botanist, who lived in Cavan town. Dr Charles Halpin
worked in Cork before he came to live in Cavan and corresponded with his
brother Nicholas. His letters contained botanical records collected by him
in Cork, which Nicholas included in his annotations. One, Coronopus
didymus, is credited to Charles Halpin in Flora Hibernica (1836).
Halpin’s botanical predecessors searched the wild untended areas of Cavan for unrecorded plants. An analysis of Halpin’s records show that the
majority were found within demesnes or the grounds of private residences. Of his fifty-eight Cavan records: twenty-six were found in Farnham
Demesne, seven at Arley Cottage (a substantial dwelling at Lough Sheelan
owned by the Farnham family), two at the Deer Park, Virginia (the
residence of the Earl of Bective), two at the See House, Kilmore (the
residence of the Bishop of Kilmore) and four at or near Churches. Halpin’s
Cavan records include: Lathraea squamaria, Listera ovata, Ophioglossum vulgatum, Platanthera bifolia, Potamogeton lucens, and Sagittaria sagittifolia.
