Description

90a.  Dalea elegans Gillies var. onobrychioides (Grisebach) Barneby

(Plate LXXXIX)

Primary cauline leaves mostly 3.5-5 cm long; spikes mostly 4-8 or (acc. Burkart, 1952, p. 253) up to 18 cm long; dorsal calyx-tooth mostly 1.6-2.4 mm long. — Collections: 10 (o).

Meadows and brushy mountain slopes, 2000-3000 m, e. slope of Andes in n.-w. Argentina (Tucuman, Salta, Jujuy) and extreme s.-e. Bolivia (Tarija).— Flowering January to March. —Representative: BOLIVIA. Tarua: Pearce in 1864 (K); Cardenas 4941 (US). ARGENTINA. Jujuy: Burkart & Troncoso 11,259 (US). Salta: Sleumer & Vervoorst 2792 (UC, US); T. Meyer 4839 (NY, UC); Lorentz & Hieronymus 537 (F, US, formerly B = Field Neg. 2038). Tucuman: Venturi 2916 (NY, UC, US), 3574 (F, US).

Dalea elegans Gill. var. onobrychioides (Grsb.) Barneby, stat. nov., based on D. onobrychioides (like sainfoin) Grsb., Abh. Wiss. Gotting. 19: 119 [Pl. Lorentz. 70]. 1874 — "210...Tucuman, in fruticetis jugi Cuesta de Siambon." — Holotypus not examined; Venturi 2916 from Cumbres de Anfama = approximate topotypus! — Parosela onobrychioides (Grsb.) Macbr., Field Mus., Bot. 4: 109. 1927.

Parosela eosina (eosin-stained, reddish) Macbr., Field Mus., Bot. 4: 109. 1927.— "BOLIVIA: Tucumilla, near Tarija, November 30, 1903, Fiebrig 2442." — Holotypus, GH! isotypi, F (2 sheets, dated Dec 30), K, US!— Dalea eosina (Macbr.) Macbr., Candollea 7: 222. 1937.

The holotypus of D. onobrychioides should be sought at GOET but the protologue is definitive. Grisebach sent to Hooker at Kew a part of Lorentz & Hieronymus 537 from Salta, identified as his species, and at the same time redescribed D. elegans, the only possible alternative, as D. stenophylla. The variety was collected first by Pearce, in Bolivia just north of the Argentine boundary (e. of Mecoya), in 1864.
