Dipcadi ursulae Blatt., View in CoL

J. Bombay Nat. Hist. Soc. 32: 735. 1928.

Lectotype (designated here): INDIA, Maharashtra, Tableland of Panchgani, Satara district, August 1925, Blatter P 74 ( BLAT Acc. No. 89500 !) . Fig. 1b View Fig

Notes: Blatter (1928) in the protologue of Dipcadi ursulae cited Blatter No. P74 as the type and gave the locality as “In grass on Tableland of Panchgani, W. Ghats of Bombay Presidency, 4,400 ft. Flowered about middle of August 1925 ”. Three relevant sheets of Blatter P74 could be located at BLAT (BLAT89498!, BLAT89499! and BLAT89500!). In addition, herbarium labels are attached to these sheets in the bottom right corner which are cross labelled as P74A (BLAT89500), P74B (BLAT89499) and P74C (BLAT89498). However, a detailed examination of the hand writing revealed that these labels were not written by Blatter, but by Dr. M.R. Almeida at a later date. All these sheets bear field tickets in the bottom left corner in the handwriting of Father E. Blatter. The field ticket on sheet BLAT89498 is labelled “ Dipcadi sp. nov., Panchgani, Aug 25” in the handwriting of Blatter but without a collection number. The field ticket on sheet BLAT89499 is labelled “ Dipcadi sp. nov., P74” but without the collection locality. The field ticket on sheet BLAT89500 is labelled “ Dipcadi sp. nov., P74, Panchgani, Tableland” in the handwriting of Blatter. These sheets cannot be considered to be part of the same gathering because Blatter’s original information varied from one sheet to the next, hence necessitates the selection of a lectotype. However, only two sheets (BLAT89499 and BLAT89500) have the original collection numbers cited by Blatter in the protologue and are therefore deemed to be syntypes (Art.9.6 and 40 of ICN, Turland et al., 2018).

Each of these two sheets bears more than one specimen, either with flowering plants alone or only flowering or fruiting scapes. Apparently, all these specimens are from the same type locality (as mentioned above), collected during August 1925. No specific date is mentioned in any of these herbarium sheets. Among the two sheets, BLAT89500 About BLAT is designated here as the lectotype (if not holotype) of D. ursulae .
