NOTE

The typification of Lagerstroemia calyculata is somewhat problematic as Kurz mentions in his protologue only ‘Martaban’ ( Burma). The only Kurz collections from Burma of Lagerstroemia calyculata known to us are in Calcutta (Kurz 1344 / 6, reads ‘Pegu’ [fide Furtado & Srisuko 1969]) and in Munich (Kurz 1344, reads ‘Karen Country and Hills. Tonkyeghat, Pellowa Zaik’, [2 duplicate-sheets, M-0146394, M-0146395]).
