Adenocaulon chilense E.F. Poeppig ex C.F. Lessing

Adenocaulon chilense E.F. Poeppig ex C.F. Lessing, Linnaea 6: 107-108. 1831.

Type material.

Chile. Antuco, [Dec 1828], E.F. Poeppig 225, diar. 755. [Holotype most likely at B and destroyed; Lectotype here designated as W* (W1889-0050720); isolectotypes: G00495616*, HAL0110867*, M0029893*, P02505554*, W0064359*, & W0064360*]. Vegter (1983) listed the date of the field trip as 1827-1829 and she listed additional possible locations of herbarium material as: B, BR, CGE, F, FI-W, GOET, K, KIEL, L, LE, LZ, MO, NY, OXF, PR, PRC, US, WRSL.

Lessing’s descriptions seem to be based on specimens that he examined at B. They were most likely collected by B staff/associates or sent to B as a gift/exchange. The Compositae herbarium at B was destroyed during WWII ( Hiepko 1987) so when duplicates can be found they are designated as lectotypes. Lessing participated in two series of papers about Compositae in the journal Linnaea. The title of Lessing’s first series of papers in Linnaea was Synanthereis Herbarii Regii Berolinensis ( Lessing 1929, 1830a, 1830b, 1930c). The second series included two papers by Lessing (1831a, 1831b), the latter of which included the type description of Adenocaulon chilense . These two articles were part of a larger series entitled De plantis in expeditione speculatoria Romanzoffiana observatis disserere pergunt AD. de Chamisso et D. de Schlechtendal, and although Chamisso’s original collections were no doubt at LE and Schlechtendal’s at HAL they both probably sent duplicates to B and it is likely that Lessing worked from the duplicate material. Interestingly the “Romanzoffiana” treatment is part of a larger series of papers that began in volume 1 of Linnaea ( Chamisso 1826). In his preface Chamisso (1826) says that the exploratory expeditions were supported by Count de Romanzoff the Imperial Chancellor in 1815, hence the name of the article. The preface mentions other collectors but does not mention Poeppig. Poeppig’s original set is supposed to be at W ( Vegter 1983) and it is likely that a duplicate was sent to B. There are two collections at W (E. Vitek, pers. comm.) and one has been selected as the lectotype.

There is some confusion as to the collecting number: on many specimens there are two numbers, the number of the printed labels differing somewhat from the “diario” numbers that are often handwritten. As a result, some records for this particular collection have the number 755 but others list 255 (likewise JSTOR-GP entries list one or the other). Some specimens clearly have both 755 & 225 printed on the labels and others do not. It is possible that the collecting number is 755 as it appears handwritten on the lectotype (and on the printed lables as "diar. 755") and other type material has 255 printed on the labels and this may be a species number. Vitek (pers. comm.) provided an example of how the collecting number might be cited and we have followed that.

Adenocaulon lechleri C.H. Schultz Bipontinus, Flora 38: 113. 1855. Type material. Chile. Ad portum Port Famine, s.d. [1850-1853], W. Lechler 1245 [Holotype: P02505548* ex Herb. Sch. Bip.; isotypes, BR0000005630134*, G00222157*, G00222158*, G00222159*, GH00000617*, M0029894*, M0029895*, NY00158067*, P02505546*, P02505547*, P03313093*]. On JSTOR-GP there is specimen from K from Herbarium Hookerianum collected by Lechler (s.n.) but with a date of 20 January 1854 and a different location. This is not believed to be type material. Chaudhri et al. (1972) gave the dates of this trip as 1850-1853.

Boerhavia nudicaulis R.A. Philippi, Linnaea 29: 37. 1857. Type material. Chile. Chillán, 1 Dec 1855, P. Germain s.n [Holotype: SGO000001680*; isotypes: G00414903*; K000500419!. K000500419 is not listed as a type in JSTOR-GP and the date printed on the label is '1856 et 1857", but it has the correct location and was originally identified as Boerhavia nudicaulis so it is probably an isotype.]

According to Lanjouw and Stafleu (1957), Germain was in Chile 1854-1890 and they indicated that there may be additional specimens at BM, F, FI, P, W and Philippi types may be at BAF (no reply).
