NUMBER OF SPECIES RECOGNIZED

DISTRIBUTION

Tropical Asia and Autralasia.

SPECIES EXCLUDED FROM COELOSPERMUM 1. Coelospermum barbatum Span. – Linnaea 15: 318 (1841) = Gynochthodes coriacea Blume, Bijdragen tot de Flora van Nederlandsch Indië 16: 993 (Oct. 1826 - Nov. 1827).

2. Coelospermum gmelinii Miq. – Annales Musei Lugduno-Batavi 3: 62 (1867) = Archangelica gmelinii DC, Prodomus Systematis Naturalis IV : 170 (1830).

REMARKS

We favor the orthographic variant Coelospermum (from coelo -, meaning with a hole in Greek) over the original spelling Caelospermum , as the author himself made the correction in his Flora javae ( Blume 1828). Brummitt &Taylor (1990) consider that the spelling corrected by the original author should be followed. The synonymy was already established by Razafimandimbison et al. (2009: 885) for Pogonolobus .

DUBIOUS SPECIES

1. Coelospermum ahernianum Elmer. – Leaflets of Philippine Botany 41: 3 (1906).

Remarks

We agree with Johansson (1988) that Coelospermum ahernianum does not belong to Coelospermum , because it does not have the characteristics of the genus as delimited here.

2. Coelospermum fragrans (Montrouz.) Baill.ex Guillaumin. – Annales de l’Institut botanico-géologique colonial de Marseille 2: 168 (1911); Figuierea fragrans Montrouz., Mémoires de l’Académie royale des Sciences, Belles-Lettres et Arts de Lyon, Section des Sciences 10: 220 (1860).

Remarks

Johansson (1988: 289) argued that this species is possibly conspecific with C. monticolum Baill. ex Guillaumin , as this latter is the only species of Coelospermum known from the type locality of C. fragrans (Île Art) . We are unable to verify this because we could not trace the type specimen of C. fragrans . The location of Montrouzier material was moved from the “Faculté de Pharmacie” to LYJB. However, the type specimen of C. fragrans is missing at LYJB and LY.

3. Coelospermum nigrescens (K.Krause) Guillaumin. – Archives de Botanique de Caen III (5): 41 (1929); Olostyla nigrescens K.Krause. – Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pfanzengeographie 39: 167 (1908).

Remarks

Johnsson (1988: 291) argued that this species is possibly conspecific with either C. balansanum Baill. or C. crassifolium J.T.Johanss. However , we were unable to trace the type specimen of O. nigrescens , which was presumably preserved at B herbarium.
