BOTANICAL EXPLORATION IN VENEZUELA - I 141 The following key summarizes the distinctions discussed above: 1. Seeds broad, a late; capsule primarily loculicidal; petals strongly spirally twisted together after anthesis Puya 1. Seeds narrow, caudate or apiculate; capsule septicidal (unknown in Cottendorfia) or sometimes about equally both; petals not twisted together after anthesis. 2. Seeds or ovules merely apiculate; placentae basal. Cottendorfia 2. Seeds long-caudate; placentae usually extending almost the height of the cell. 3. Petals white, colorless, separate after anthesis; sepals not over 5 mm. long, thin, flat; plants slender. Lindmania 3. Petals brightly colored, more or less massed together after anthesis but not twisted; sepals larger and firmer; plants relatively robust Connellia Connellia nutans L. B. Smith, sp. nov. Dense aggregata, plus minusve caulescens (?), planta fructifera metralis vel ultra; foliis multis, caulem quaquaverse denseque vestientibus, ca. 3 dm. longis, vaginis amplis, basi medioque integris, dissite perobscureque punctulatis, brunneis, lucidis, laminis anguste triangularibus, a cumin at is, ad 3 cm. latis, basi extrema dentibus ad 2 mm. longis dense armatis alibi integris, infimis delapsis; scapo decurvato, 14 mm. diametro, scapi bracteis erectis, dense imbricatis, subfoliaceis sed omnino inermibus; inflorescentia bipinnatim paniculata, 2-7 dm. longa, 8-12 cm. diametro, subthyrsoidea, glabra; bracteis primariis e late ovato acuminatis; ramis strictis, gracilibus, floriferis brevibus sed fructiferis ad 18 cm. longis et bracteas multo superantibus; bracteis florigeris oblongo-lanceolatis, 17 mm. longis f brunneis, tenuibus; pedicellis gracillimis, 10 mm. longis; sepalis ellipticis, obtusis, 14 mm. longis, carinatis, brunneis, lucidis; petalis bene unguiculatis roseis, lamina suborbiculari; staminibus styloque inclusis; ovario supero; seminibus caudatis (Fig. 20c-f). Type collected along base of east-facing high sandstone bluffs, Ptari-tepuf, state of Bolivar, alt. 2410-2450 m., November 7, 1944, Julian A. Steyermark 59933', common type on bluffs, in dense mats. The flower and seed of Connellia nutans closely resemble those of C Augustae, but the deflexed inflorescence of the former quickly distinguishes it. Also even in fruit the branches of C.Augustae are very short. Steyermark 59611, from south-facing high sandstone bluffs, Ptari-tepui, October 30, 1944, alt. 2400-2410 m.. is sterile, but so closely resembles the type of C. nutans that it seems very likely that it is the same species.
