35. Calliandra glaziovii Taubert, Flora 71: 75. 1892.-"Habitat in Brasilia austro-orientali loco non indicato [supplied by Glaziou, 1905: 188: ‘Serra do Campanema [sic, properly Capanema, near 20°10'S, 43°40'W, MINAS.’], Glaziou n. 23640." — Holotypus, collected 18 Jun 1882 (fl), †B = F Neg. 12431- isotypi, K! = NY Neg. 19861, P (2 sheets)!.

C. bracteosa sensu Glaziou. 1905: 188 (Glaziou 13787, P!); non Bentham, 1846.

Shrubs of unknown stature with stout lignescent long-shoots and in each primary lf-axil a short-shoot thatched in dry striate stipules, the young stems, lf- axes, and peduncles pilose-pilosulous with fine white hairs to 0.4-1.1 mm, the lvs strongly bicolored, the firm plane lfts glossy dark-olivaceous and glabrous above, paler and appressed-pilose beneath, the dense many-fld capituliform racemes arising singly from a succession of brachyblasts, each subtended by a pair of efoliate stipules; phyllotaxy distichous. Stipules of primary lvs (excluding prominent lf-spur) lanceolate or triangular-acuminate 6-12 x 1.7-3.5(-4) mm, early dry papery, striately nerved, long persistent, those of brachyblasts similar but a trifle narrower. Lf- formula (i—)ii(—iii)/27—37; lf-stk of primary lvs 13-33 mm, the petiole 8-18 mm, at middle 0.9-1.5 mm diam, the one interpinnal segment (or the longer of 2) 8-15 mm, the ventral groove bridged at insertion of pinnae; rachis of longer pinnae 5.5-7.5 cm, the longer interfoliolar segments 1.2-2.1 mm; lft-pulvinules 0.2-0.25 x 0.5-0.6 mm; lfts gently decrescent along upper ¼ of rachis and close to its base, otherwise subequilong, the blades linear from slightly dilated obtu-sangulate base, either obtuse or apiculate, straight or nearly so, those near mid-rachis 9-12 x 1.8-2.6 mm, 4.3-5 times as long as wide; midrib forwardly displaced to divide blade 1:1.5-2, weakly pinnately branched, the 2 posterior primary nerves very short. Peduncles stout 8-25 mm, 1-2-bracteate near or above middle, the bract(s) lanceolate striate 2.5-4.5 mm, persistent; capitula ±20-40-fld, prior to anthesis globose, disregarding androecium becoming plumply ellipsoid, the calyces contiguous, the lowest fls subtended by a bract similar to that on peduncle, the rest ebracteate, all homomorphic; pedicels stout 0.9-1.5 x 0.9-1.2 mm; perianth 5-merous, the calyx striately ±20-nerved, minutely puberulent, the corolla externally nerveless, thinly appressed-silky, the tip of lobes barbellate; calyx deeply campanulate 4-4.5 x 2.4—3.2 mm, the broadly obtuse, apically convex teeth 0.8 1.1 mm; corolla 8.5-12.5 mm, the ovate lobes 2.5-4.2 x 1.7-3 mm; androecium 22-36-merous, (28-)32-42 mm, the stemonozone 2.4—3 mm, internally thickened, the tube 5-7.5 mm, the tassel red-purple; intrastaminal nectary 0; ovary sessile, at anthesis glabrous. Pod unknown.

In habitats as yet unknown, to be expected in scrub- woodland near 500 m, collected twice by Glaziou in 1882 in s.-e. Minas Gerais (near Ouro Preto and Mar d’Hespanha), not since seen. — Fl. I, VI, all capitula and all fls of each capitulum simultaneously expanding.

In the protologue Taubert compared C. glaziovii with C. abbreviata Bentham, but it appears more closely related to C. subspicata Bentham, which is similar in the thatched brachyblasts, bracteate peduncles, and many-flowered capituliform racemes. The distantly allopatric C. subspicata differs, however, in dorsally glabrous, not appressed-silky, leaflets and in white, not red-purple, androecium.
