BOTANICAL EXPLORATION IN VENEZUELA - I 143 Guzmania confinis L. B. Smith, sp. nov. Acaulis, florifera ad 5 dm. alta; foliis strictis, dense rosulatis, ad 23 cm. longis, viridibus (ISteyermark), vaginis ellipticis, lamina fere aequantibus, utrinque punctulato-lepidotis, laminis anguste triangularibus, 23 mm. latis, subtus obscure punctulato-lepidotis, supra densissime cinereo-lepidotis, margine revolutis; scapo erecto, gracili; scapi vaginis subfoliaceis, densissime imbricatis, purpureis; inflorescentia dense bipinnatim paniculata, cylindrica; bracteis primariis eis scapi similibus sed gradatim brevioribus, infimis flores multo superantibus; ramis subabortivis, flores 3 subfasciculatim gerentibus; bracteis florigeris suborbicularibus, 5 mm. longis, quam sepala multo brevioribus, membranaceis, sparse lepidotis; sepalis oblongis, late obtusis, 10 mm. longis, ad 6 mm. connatis, membranaceis, sparse lepidotis; petalis 20 mm. longis, alte conglutinatis, nudis, albis, laminis ellipticis; staminibus styloque inclusis; capsula cylindrica, rostrata, 2 cm. longa (Fig. 22, a-b). Type collected on limestone outcrops of Paramo de Tama, near Colombian-Venezuelan boundary, state of Tachira, alt. 3045-3475 m., July 15, 1944 , Julian A. Steyermark 57380; terrestrial, the common dominant type, forming dense colonies. Guzmania confinis is much more conspicuously lepidote on the upper surface of its leaves and bracts than on the lower, a character shared by G. palustris, but not by its other near relatives, G. Mosquerae and G. crypto nth a. Guzmania palustris has a much stouter habit and broader leaves and bracts than G. confinis and its flowers are about twice as large. Mez has placed such species with highly connate sepals in Thecophyllum, but in every instance that I have been able to check, the corolla proves them to be typical of Guzmania. Guzmania retusa L. B. Smith, sp. nov. Acaulis; foliis suberectis, 5 dm. longis, inflorescentiam superantibus, utrinque minute obscureque punctulato-lepidotis, vaginis magnis sed baud distinctis, laminis lingulatis, 6 cm. latis, apice late rotundatis et retuso-apiculatis, subtus pallide purpureis, supra purpureo-maculatis, margine anguste purpureis; scapo erecto, gracili; scapi bracteis erectis, dense imbricatis, ellipticis, apiculatis, punctulato-lepidotis; inflorescentia simplicissima, dense ellipsoidea, 4.5 cm. longa, 2 cm. diametro, apicem usque fertili; bracteis florigeris orbicularibus, leviter convexis, 2 cm. diametro, sepala superantibus, coriaceis, lucidis, punctulato-lepidotis, nervatis vel fere laevibus; floribus subsessilibus; sepalis ellipticis, 13 mm. longis, aequaliter ad 5 mm. connatis, carinatis, coriaceis, apice sparse lepidotis; petalis 23 mm. longis, flavis, laminis late ellipticis; staminibus styloque inclusis (Fig. 23, a-c). Type collected on lower south-facing slopes between Rio Karuai and first ridge above Rio Karuai, Ptari-tepuT, state of Bolivar, alt. 1220 m., November 28, 1944, Julian A. Steyermark 60677; terrestrial. I hesitate to describe a species from two specimens coming from
