REMARKS

Richard (1847) provided a description for the name Blumea dregeanoides and thereby validated it. In that publication he gave a reference to Blumea dregeanoides C.H. Schultz in pl. Schimp. Abyss., sect. II, 633 et 1297. The reference goes to a printed herbarium label of a series of exsiccata distributed on the occasion of “ Schimperi Iter Abyssinicum ” (section secunda): prope Aguar ( Abyssinia: Ethiopia), 8 April 1839. This series was distributed to numerous herbaria.

After a thorough searching in different herbaria around the world, we found 24 sheets; BR(2), HEID(1), P(5), M(1), S(2), MO(1), TUB(4), US (2), W(1), CAL (2). In most of these herbarium sheets printed label contains an abbreviation ‘u. i. 1842 ’. The ‘u.i.’ refers to “ Unio Itineraria ”, also known as the “Botanische Reiseverein”, which was a 19th- century joint stock corporation, formed solely to send botanists on expeditions to gather herbarium specimens. Schimper, Georg Wilhelm (1804?, Mannheim-1878, Adoa, Abyssinia) was the Reiseverein's most important, most expensive, and, aside from Welwitsch, most difficult wanderer ( Wörz 2007).

In protologue, Richard also added that the species is very polymorphic, some samples likely annuals are only one to two inches tall, while others are perennials with stems sometimes reaching two feet or more. In all the 24 retrieved sheets the different forms are recognized. Richard mentioned four localities in protologue; Chire (Quartin-Dillon), Choa and Techeleukote (Antoine Petit), Wogera (Schimper 1297)and near Ferrokoba (Schimper633). As all the found 24 sheets of B.dregeanoides are syntypes after Art.9.6 of Shenzhen Code, lectotypification was necessary according to Art. 9.3. After dissolution of Unio itineraria most of the collections of Schimper went directly to P. The sheet P033041 is well preserved and thus chosen as the lectotype of the name Blumea dregeanoides .
