Lagerstroemia subcostata Koehne

Lagerstroemia subcostata Koehne (1883) 20; Backer (1964) 255; Furtado & Srisuko (1969) 281,f. 35a,35b:a;T.C. Huang (1993) 876,pl.435;H.N.Qin & S.A. Graham (2007) 281;H.N.Qin et al.(2008)f.300:1–5. — Lectotype (here designated): Oldham 119 / 2 (holo GH GH00099295 photo seen), China, Taiwan.

Notes — 1. Lagerstroemia subcostata from China (and Taiwan) was included in the Flora of Java ( Backer 1964) as locally cultivated, but we think it is only sporadically grown in botanic gardens. The flowers are recorded as fragrant. From Malesia we have seen only Schuurman 134 (L, flowers), cultivated in the botanic garden at Bogor, and Steiner 1811­A (= PNH 40084) (L, fruit), cultivated in Los Baños.

2. Both L. subcostata and L. indica have a narrow annulus in the throat of the calyx tube, a character shared with some more Chinese species.
