Description
PLATE LXXIX Dalea coerulea (Linnaeus f.) Schinz & Thellung, prototype of a group of potentially fruticose, tropical-montane daleas with expanded leaflets and bicolored flowers, the ample banner white and gland-sprinkled distally but colored at base like the wings and keel, vivid blue or less often purple. The range of D. coerulea, when adult a shrub 1.5 -3 (exceptionally 5) m tall, extends at middle elevations along the Andes, mostly on the east slope, from Cordillera Oriental in Norte de Santander, Colombia, s. to Cuzco in Peru. Northward from Chachapoyas in Peru the species is represented by var. coerulea, relatively small-flowered, and southward through Peru by a large-flowered var. longispicata (Ulbrich) Barneby, with keel-blades ±6-8 mm long and proportionately massive spikes of calyces. Among Andean daleas, D. coerulea and D. ayavacensis (Pl. LXXX) alone have elongate, aristiform and plumose calyx-teeth; the locally sympatric D. ayavacensis differs in the linear glands traversing the length of the intercostal panels of the calyx. — Habit × 1; the rest × 5. var. coerulea: 1) top of flowering branchlet; 2) stipules; 3) segment of leaf-rachis, showing spiculiform intrapetiolular glands; 4) flower (from Colombia); 5) calyces + bract (both from Ecuador); 6) banner, ventral and profile views; 7) androecium; 8) pods. var. longispicata: 9) flower.
