Indigofera glandulosa J.C.Wendl.

In 1798 Wendland described I. glandulosa with the German name ‘Drüsige Indigo’. I asked Göttingen to search the Wendland collection for a specimen of his I. glandulosa , but I have not received any answer to this request. According to Sanjappa (1995) Wendland’s herbarium in Hanover was destroyed.

In 1803 Willdenow described an I. glandulosa with the same German name, contributing the epithet to Roxburgh. In the Willdenow herbarium, sub nr. 13891, there is a specimen collected by Rottler sent to Willdenow by Klein, annotated in Rottler’s handwriting with Indigofera glandulosa Roxb. This specimen was the base of Willdenow’s I. glandulosa as the sheet also contains comments in Willdenow’s handwriting.

As Wendland and Willdenow were describing the same species, indicating it with the same German name, I have selected the Rottler specimen from the Willdenow herbarium as the neotype of Wendland’s I. glandulosa . The synonymy becomes:

Indigofera glandulosa J.C.Wendl. (1798) 55; de Kort & G. Thijsse (1984) 119. — Indigofera glandulosa Roxb. ex Willd. (1803) 1227; Roxb. (1832) 380; Wight & Arn. (1834) 199; Backer & Bakh. f. (1964) 590. — Neotype (here designated): Rottler 750 (B, Hb. Willd. 13891), India, ‘ Mirittapadu’, 1794.

Indigofera hirsuta L.

In 1837 Blanco described Indigofera angustifolia . This species was renamed Indigofera tinctoria by Naves (1880). Both names are illegitimate. Merrill (1918) identified this plant as Indigofera hirsuta L. De Kort & Thijsse (1984) named Merrill’s representative specimen Spec . Blanc. 403 as the type of the names of Blanco and Naves. However, as no Blanco material of his I. angustifolia is known, they should have selected a neotype. As such I designate Merrill Spec . Blanc 403. In the synonymy of I. hirsuta it becomes:

Indigofera angustifolia Blanco (1837) 596, non L.; (1845) 403; (1879) 394; Merr. (1918) 79. — Indigofera tinctoria Náves (1880) t. 163, non L. — Neotype (here designated): Merrill Spec . Blanc. 403 (L; iso BM, K, US), Philippines, Luzon, Pangasian Prov., Umingan.

Indigofera linifolia (L.f.) Retz.

In 1841 Spanoghe described a new species Indigofera albicans based on ‘ Hallia glauca Zipp. ’. Zippelius wrote the name ‘ Hallia glauca’ on labels of several specimens he collected in Timor. One of these specimens bears a Spanoghe label ‘ Indigofera albicans ’, but lacks the indication that Zippelius collected it. As this specimen was seen and annotated by Spanoghe this collection (L 908.116-1306) is selected as the lectotype of I. albicans Span. In the synonymy of I. linifolia it should read:

Indigofera albicans Span. (1841) 190. — Lectotype (here designated): Anon (Zippelius?) s.n. (L, L 908.116 - 1306 ), Timor.

Indigofera tinctoria L.

In 1837 Blanco described Indigofera tinctoria Blanco , seemingly with no references to the earlier description of I. tinctoria by Linnaeus. According to Merrill (1918: 179) the Blanco species is identical with the Linnaean one. De Kort & Thijsse (1984: 136) followed Merrill (1918) and placed the Blanco name in the synonymy of I. tinctoria L. As the type of I. tinctoria Blanco they cited Merrill’s representative specimen Spec . Blanc. 826. However, this cannot be the type. As no Blanco material of his I. tinctoria is known they should have selected a neotype. Here I select as neotype of I. tinctoria Blanco Merrill Spec . Blanc 826. In the synonymy of I. tinctoria L. this becomes:
