Smithsonia viridiflora (Dalzell) C.J.Saldanha, J. View in CoL Bombay Nat. Hist. Soc. 71: 75. 1974.

An epiphytic orchid endemic to the Western Ghats. It can be recognized by its corymboseumbellate inflorescence (not exceeding the leaves), greenish-white flowers, and conical rounded fleshy spur. Like the preceding species, many workers treated this species under different genera. Cooke (1908) assigned the species to genus Sarcochilus (as Sarcochilus viridiflorus ) which became a later homonym ( non Hooker, 1890) and hence illegitimate. Santapau (1948) provided a replacement name, Sarcochilus dalzellianus , which was later transferred to Aerides Lour. by Garay (1972). Moreover, Pradhan (1979) transferred it to Loxoma but failed to cite the basionym, which made the combination invalid. Santapau and Kapadia (1966) had a similar opinion as Kuntze (1891) for treating this species in Gastrochilus but they erroneously cited it as Gastrochilus dalzellianus (Santapau) Santapau & Kapadia. However, Malaysian species of Gastrochilus are unique in having a wide sac, which is entirely replaced by a narrow spur in G. dalzellianus ( Holttum, 1960) .

Bokil et al. (2019) lectotypified Micropera viridiflora , but while doing so, they erroneously cited the locality as ‘Koyana valley, Mahabaleshwar, Satara District’ which appears to be copied from Cooke’s collection, possibly made in May 1892 (K001222283). Similarly, the isolectotype choice presented by Bokil et al. (2019) is also excluded here. The remaining collection of M. viridiflora by Dalzell housed at K (K001222284: with Stocks label ‘Orchideae no. 26’) may not be a single gathering.
