Note — The only specimen mentioned by Miquel for M. macrophylla is: “ Java, tusschen struiken bij Tjikoja”. According to the first author this is the specimen Zollinger 1147. The Utrecht herbarium (now at L) holds a specimen labelled as Typus fragment. The only other information is on an older label saying in Miquel’s handwriting: “ Mucuna macrophylla M, Java ”. This fragment consist of a lateral leaflet of 19.5 by 13.5 cm, much larger than usually in M. macrophylla . Prain (1897b: 407) mentions the name M. junghuhniana in observations sub M. imbricata . It is unclear whether or not he meant to make a new combination. Burck (1893) mentions several localities for his species M. blumei : Java, Koeripan, prope Buitenzorg et Oengarang, Forbes in herb. Lugd. Bat. The first locality refers to Blume 771. The second and third localities to a Junghuhn collection (Junghuhn 193); the L duplicate of that collection consist of a piece of a branch and a leaf, the sheet bears three labels: one attached to fragment ‘Jul montis Rembang’ and two that refer to ‘Oengarang’, one with the months Mei, Jun., the other with the months April-Jun. The fourth locality probably refers to Forbes 1417, Lampongs, Kota-Djawa, the type of M. ovalis Baker f. This specimen was collected in Sumatra. For M. blumei the Blume specimen was selected as the lectotype. The twigs of older specimens tend to have a more appressed indumentum. Forbes 1417 (the type of M. ovalis ) has both pseudopanicles and very short pseudoracemes with only 1–2 brachyblasts. A Teysmann specimen (4492 HB), collected in ‘Lampongs’, probably also belongs here. The flower colour of Schmutz 4292 is given as blue (‘blaublühend’).
