Ensete schweinfurthii

Ensete schweinfurthii (K. M. Schumann & O. Warburg ex K. M. Schumann in A. Engler et al (eds.) Das Pflanzenreich. Engelmann, Leipzig, 1900 - . 4, 45 : 14 (1912)) E. E. Cheesman, Kew Bulletin 2 (2): 103 (1947).

Accepted name Ensete ventricosum (F. M. J. Welwitsch) E. E. Cheesman, Kew Bulletin 2 (2): 101 (1947) and R. E. D. Baker & N. W. Simmonds, Kew Bulletin 8 (3): 405 (1953) with correction in Kew Bulletin 8 (4): 574 (1953).
Synonyms 1. a. Musa schweinfurthii K. M. Schumann & O. Warburg ex K. M. Schumann in A. Engler et al (eds.) Das Pflanzenreich. Engelmann, Leipzig, 1900 - . 4, 45 : 14 (1912). (sometimes abbreviated to [1. b.] Musa schweinfurthii K. M. Schumann) but not [1. c.] M. schweinfurthii of Hutchinson & Dalziel FWTA ed. 1., 2 (2): 328 (1936) which is Ensete gilletii.

2. Musa chevalieri F. Gagnepain, Bull. Soc. Bot. France 55 Mem. 8: 87 (1908)

3. Musa martretiana A. J. B. Chevalier, Bull. Soc. Acclim. Paris: 79 (1907) nomen, and in Rev. Bot. Appl. 14: 507 (1934) but not M. martreti A. J. B. Chevalier ex Tribune Hortic. 3: 38 (1908) nomen nudum and likely err. typ. for M. martretiana.

4. Musa riperti A. J. B. Chevalier, Expl. Bot. Afr. Occ. FranÁ. 1: 632 (1920) nomen.

Authorities The source for the accepted name is Baker and Simmonds 1953 as corrected (see below).

The sources of the synonyms are as follows:

1. a. is from Cheesman 1947a, 1. b. is from Lock 1993, 1. c. is from Hepper 1968.
2. is from Cheesman 1947a ex Hutchinson & Dalziel 1936 but this is a mistake, see below.
3. & 4. are from Cheesman 1947a ex Hutchinson & Dalziel 1936 but Baker & Simmonds 1953: 409 reject these taxa as nomen nudum.

The World Checklist of Monocotyledons gives Ensete schweinfurthii (K.Schum. & Warb.) Cheesman, Kew Bull. 2: 103 (1947 publ. 1948) (synonym Musa schweinfurthii K.Schum. & Warb. in H.G.A.Engler (ed.), Pflanzenr., IV, 45: 14 (1900)) as a synonym of Ensete ventricosum (Welw.) Cheesman, Kew Bull. 2: 101 (1947 publ. 1948) which is given as the accepted name.

Distribution South-east Sudan.
Description See Ensete ventricosum for a description of this polymorphic species.

See Musa schweinfurthii for a description of the type.

Comments Cheesman created Ensete schweinfurthii as a new combination (number 11 out of 25) in a brief note in his 1947 paper reviving the genus Ensete. Cheesman revived one and created 24 new Ensete species in that paper but acknowledged that field study might reveal synonymy. Baker and Simmonds' 1953 review of the genus Ensete in Africa radically reduced the number of species either reducing or rejecting most of Cheesman's African Ensete. Baker and Simmonds' original paper reduced Ensete schweinfurthii to a synonym of Ensete edule. However, when it was noticed that, via Musa ventricosa, Ensete ventricosum took priority over Ensete edule by three years a substantial correction appeared in the following issue of Kew Bulletin that reduced Ensete schweinfurthii to a synonym of Ensete ventricosum (please refer to R. E. D. Baker & N. W. Simmonds, Kew Bulletin 8 (4): 574 (1953)).

The synonymy of this plant is a little complicated. The original description of Musa schweinfurthii by Schumann was rather poor but according to Baker & Simmonds 1953 "the large leaf in Herb. Kew strongly suggests [E. ventricosum]." This is not exactly a ringing endorsement of the identity of the plant but for the time being it is taken as adequate. The type species, Musa schweinfurthii was confused with Musa gilletii De Wildeman by Hutchinson and Dalziel who were apparently misled by comments of Chevalier. This led to Musa chevalieri wrongly being brought into synonymy. Hutchinson and Dalziel also listed Musa martretiana and Musa riperti as synonyms of the type but these names were later rejected as nomen nudum by Baker & Simmonds.

The reference by Lock 1993 to E. schweinfurthii (Schweinf.) Cheesman in K. B. 2: 103 (1948) should be changed to Ensete schweinfurthii (K. M. Schumann & O. Warburg) E. E. Cheesman. Please follow the link to Lock 1993 (via Bibliography) for more comments about this item.
