039087D9FF95927AFF78FB175CEAFA19.taxon	biology_ecology	PHENOLOGY. — From herbarium specimens, flowers have been recorded from April through November (except in August) and fruits have been recorded all the year. ECOLOGY. — The epithet is very well fitting the ecology of this species usually living on rocks (saxicolous) and especially the cracks of the rocks (chasmophyte), Fig. 2 C. However, Dendrobium petrophilum is also able to grow at the base of trees and shrubs (but not truly epiphytic, Fig. 2 D) where it can get some shelter from the harsh natural environmental conditions (extreme drought, strong prevailing wind, full sun, rocks with no or little soil) encountered in this type of “ acidic maquis ” (Fig. 2 A) which is very different from the typical New Caledonian “ ultramafic maquis ”. The bedrock is a siliceous schist and its derived soil (if any) is a kind of ferric acrisol (Latham 1975). Some other species like Codia microphylla Vieill. ex Guillaumin, Homalium buxifolium Däniker, Leichhardtia oubatchensis, Phyllanthus golonensis M. Schmid and Tristaniopsis ninndoensis J. W. Dawson are well adapted to this type of maquis.	en	Pignal, Marc, Laudereau, Christian, Gâteblé, Gildas, Laudereau, Pierre-Louis (2022): Dendrobium petrophilum (Kraenzl.) Garay ex N.

039087D9FF95927AFF78FB175CEAFA19.taxon	conservation	CONSERVATION STATUS. — A first IUCN assessment was made on 29 January 2016 by the local Red List Authority (RLA Endemia) which proposed the species as Data Deficient (DD) because of too much taxonomic uncertainty. This assessment has been published in 2020 on the IUCN Red List Portal (Butin et al. 2020 a). Since, the species has been rediscovered in 2018 in the type locality (locus classicus) by two of the authors of this note, and in other places by other people, since then, we have been able to clarify its taxonomic status. A second IUCN assessment by the RLA Endemia took place on 20 November 2020 and proposed the species as EN B 1 ab (iii, v) + 2 ab (iii, v). We fully agree with this proposed status because of the very high fire threat. According to some observations (D. Fleurot pers. comm.), after a rapid fire event, the pseudobulbs are drying out and can be observed several years after the event (Fig. 2 D). In addition, the species is protected in the Province Nord (Northern province).	en	Pignal, Marc, Laudereau, Christian, Gâteblé, Gildas, Laudereau, Pierre-Louis (2022): Dendrobium petrophilum (Kraenzl.)

039087D9FF95927AFF78FB175CEAFA19.taxon	discussion	NOTES In 1972, H. S. MacKee collected a sterile orchid at Arama (MacKee 25584, Monts Ninndo, P 00115081) and apparently sent some pseudobulbs of it to P for greenhouse cultivation, presumably because MacKee was thinking this orchid was interesting and worthwhile further ex situ examination and flowering. At P, the first author did not find any record of its cultivation and flowering in the archives of Service des Cultures. Hallé (1974, mss. in herb) identified this specimen as D. multilobatum Guillaumin and later, synonymized this name under D. oppositifolium in his New Caledonian flora of Orchidaceae (Hallé 1977: 122). Another interesting and related specimen (MacKee 21630) was collected fertile in 1970 and a plant was sent to Paris Museum greenhouses where it flowered on 30 May 1974. Hallé collected the inflorescence of it at P and added it to the original specimen (P 00115083). Because the original specimen was also initially determined as D. multilobatum by Hallé, we have checked in detail the flowers of the cultivated specimen (that are slightly smaller than the ones of the in situ plant) to confirm labels of MacKee 21630 and 25584 have not been mixed in P greenhouses. We conclude both the in situ and ex situ flowers belong to D. oppositifolium so labels were most probably not mixed. It is to be noted that many New Caledonian orchids and particularly Dendrobium have been exported to P and other Europeans institutions and nurseries for ex situ cultivation (Gâteblé 2015: 24 - 27, 294).	en	Pignal, Marc, Laudereau, Christian, Gâteblé, Gildas, Laudereau, Pierre-Louis (2022): Dendrobium petrophilum (Kraenzl.)

039087D9FF979277FF20FA365FDFFE04.taxon	biology_ecology	ECOLOGY. — This species lives as an epiphyte on trees, usually in rainforests, forest edges and sometimes in more open vegetation conditions (Araucaria spp.) at higher altitudes. Most of the observations and specimens are from open or low forests ranging from 200 to 1200 m above sea level. Because Dendrobium oppositifolium seems to favour semi-shaded conditions, it has been rarely observed in dense rainforests where it might occur within the difficult to access canopy of the large and highest trees.	en	Pignal, Marc, Laudereau, Christian, Gâteblé, Gildas, Laudereau, Pierre-Louis (2022): Dendrobium petrophilum (Kraenzl.)

039087D9FF979277FF20FA365FDFFE04.taxon	conservation	CONSERVATION STATUS. — It is a common endemic species distributed from the South to the North of mainland Grande Terre and even on Île des Pins [Isle of Pines]. Even if some plants and populations are threatened by anthropogenic fires and by illegal removal (the species is protected in the Northern province) from plant and orchid hunters, the species is globally not threatened. It has been successfully cultivated in Paris museum greenhouses as well as by local orchid growers, but remains very difficult to maintain. We agree with the RLA Endemia assessment made on 29 January 2016 (Butin et al. 2020 b) classifying the species as Least Concern (LC).	en	Pignal, Marc, Laudereau, Christian, Gâteblé, Gildas, Laudereau, Pierre-Louis (2022): Dendrobium petrophilum (Kraenzl.)
