Orchids collected on Mr. Moulton’s expedition to Mt. Batu Lawi
J.J. Smith’s 1912 article reports on orchid specimens collected during J.C. Moulton’s 1911 expedition to Mount Batu Lawi, a remote peak in the Limbang district of Sarawak that had been reached by very few Europeans before that journey. Published in the Journal of the Straits Branch of the Royal Asiatic Society, the piece serves as a taxonomic companion to Moulton’s full expedition narrative, which appears in the same volume.
Summary
Smith’s article presents the orchid collections made by the botanical collectors who accompanied Moulton’s party as it traversed the Limbang and Madihit river systems and crossed the intervening mountainous terrain to reach the base of Batu Lawi. The expedition departed Kuching on 2 May 1911 and reached the mountain by 29 May, passing through a succession of ecological zones from lowland riverine jungle to cold, moss-draped limestone slopes at altitudes exceeding 5,000 feet. The orchid record thus captures the flora of a region that was, at the time of publication, almost entirely unknown to Western botany, having been preceded by only Sir Spenser St. John’s 1858 journey and a handful of brief Sarawak Government visits.
The expedition narrative published alongside Smith’s article provides the essential ecological and geographical context. The upper slopes of Batu Lawi and the adjacent Selinguid peak were characterised by low-growing gnarled shrubs thickly encrusted with moss over massive limestone blocks, with temperatures falling to 62°F and persistent cloud cover that obscured the peaks for most of the party’s time on the mountain. The remarkable sparseness of animal and insect life observed at these elevations, combined with the dense humidity and the absence of any human habitation for stretches of up to 13 days, points to a specialised and potentially rich but entirely undocumented flora of which the orchids form a significant component.
The article’s significance lies in establishing a baseline botanical record for one of the last unexplored highland regions in Sarawak. The collections, though necessarily limited by the hurried and arduous character of the expedition—31 of the 40 days from Limbang to Claudetown were spent in actual travelling—were described by Moulton as “surprisingly rich in new and rare species,” a characterisation that extends to the orchid material reported by Smith.
Key Findings
- The expedition departed Kuching on 2 May 1911 and reached the base of Batu Lawi on 29 May 1911, after a 27-day journey from the coast (pp. 5, 39).
- The base of Batu Lawi sits at approximately 3,500 ft above sea level; the higher peak rises a further ~2,700 ft, with the highest point reached by the party at 5,660 ft on the southern end of the mountain (pp. 40, 42).
- Temperatures at altitude ranged from 62°F to 67°F, with continuous rain and cloud cover throughout the party’s time on the mountain (pp. 34–40).
- The party spent 13 days between Penribut’s house (at 2,100 ft on the Madihit) and Batu Lawi without encountering any other human habitation (p. 56).
- Only three Europeans had previously reached the Kuala Madihit—the real starting point for journeys into the interior—during the preceding 20 years: O.F. Ricketts (1895), W.F. de V. Skrine (1911), and Mr. Ward (1907) (p. 2).
- The river journey from Limbang to the Kuala Madihit occupied 10 days; the overland walk from the Madihit to Batu Lawi took 12 days, with the return journey requiring a further 4 days on foot and 5 days by boat (p. 56).
Conclusion
Smith’s article documents the orchid flora of a mountain region that was, in 1912, one of the last places in Sarawak to be scientifically explored. By reporting the collections from Moulton’s expedition, the article provides the first Western botanical account of the highland vegetation of the Batu Lawi area, establishing a reference point against which future collections from this remote part of the island could be compared.
Context
- The expedition was undertaken under the auspices of the Sarawak Government, with Moulton acting in a quasi-official capacity; the article reflects the colonial scientific enterprise of cataloguing the natural history of territories under British administration in Borneo.
- The primary archival context is the Sarawak Museum, where the collected specimens would have been deposited; the article contributes to the broader historiography of early twentieth-century botanical exploration in Sarawak, alongside contemporaneous work by Ridley, Copeland, and others associated with the museum.
