Email: [email protected] (Manuscript received 25 October 2010; accepted 1 June 2011) ABSTRACT: The lectotypification of Bauhinia ornata Kurz var. kerrii (Gagnep.) K. Larsen & S.S. Larsen based on Kerr 1740 (K) presently stands good though there is a collection of Kerr 1740 at P where Francois Gagnepain’s types are supposed to be present. KEY WORDS: Leguminosae, Caesalpinioideae, Bauhinia ornata var. kerrii, typification. TAXONOMIC TREATMENT Gagnep. cited ‘Siam: Doi-sootep, 840 m. alt.; grande liane ligneuse, à fleurs blanches et anthères roses, dans la jungle verte près d’un cours d’eau, n◦ 1740 [Kerr]’ Typification of Bauhinia ornata var. kerrii along with the morphological description. The In the present communication, a thorough review of collection data ‘SIAM: Chiengmai. Doi Sootep, 840 m., the typification of Bauhinia ornata Kurz var. kerrii 1.iv.11 / 1.4.11, large woody climber, flowers white, (Gagnep.) K. Larsen & S.S.

KERR 1740’ of the specimen available at P (Fig. 1) Larsen and Larsen (1980: 208) treated Bauhinia matches with the protologue. However, I have noticed kerrii Gagnep. as a variety of B. ornata Kurz, i.e. B. that the measurement of the leaves, inflorescence, ornata Kurz var. kerrii (Gagnep.) K. Larsen & S.S. petals, stamens and style of the P specimen do not fully Larsen and cited ‘TYPE: Kerr 1740, Thaïlande, K’. match with those given in the protologue. In the Larsen and Larsen (1980a: 41) gave the type details of protologue (Gagnepain, 1912: 173), the relevant B. kerrii as ‘Kerr 1740. Thailand: Chiang Mai, Doi measurement is given as follows: Folia 9-13 cm. longa, Suthep (Lecto- K)’ but from Stafleu and Cowan, TL2 1: 8-12 cm. lata; petiolo 4-9 cm. longo; inflorescentia tota 904. 1976, I came to know that Francois Gagnepain’s types are at P. Through ‘colhelper’ I requested for the 13 cm. longa; petala 2 cm. longa, 7-10 mm‘cm.’ lata; relevant specimens at P because there might be a stylus 14 mm. longus whereas in the P specimen the specimen that qualifies as holotype or there might be leaves are 6.2-13.4 × 5.5-11.7 cm; petiole 3-8.8 cm syntypes which are to be given priority for designating a long; inflorescence 8.5-16 cm long (the longest is c. 13 lectotype under Art. 9.10 (McNeill et al., 2006). cm if the curved axis of the inflorescence is not I received the image of a specimen at P (bar code followed); petals 1.4 -2 × 0.5-1 cm and the style ranges no.
