150 FIELDIANA: BOTANY, VOLUME 28 ad 25 cm. longis, ad apicera versus minute tuberculatis; bracteis florigeris elliptic is, apiculatis, 5 mm. longis, quam pedicellis multo brevioribus; floribus patentibus, saepe secundis; pedicellis 1 cm. longis, gracilibus, tuberculatis; sepalis anguste triangularibus, ad 27 mm. longis, ecarinatis, subcoriaceis, densissime grosseque tuberculatis; petalis delapsis solum cognitis, linearibus, 5 cm. longis, nudis; staminibus verisirailiter inclusis; ovario 4/5 supero; ovulis caudatis (Fig. 22, c). Type collected along dry grassy slopes following quebrada, between Beguilla and Mucuchachi', state of Me'rida, alt. 1065-2430 m., May 4, 1944, Julian A. Steyermark 56297. Pitcairnia tuberculata is strongly reminiscent of P. echinata but has naked petals, much smaller sepals and floral bracts and much more complex indument on the sepals. The indument of P. tuberculata consists of rods so sculptured as to be dendritic in form. On account of the naked petals, P. tuberculata would fall close to P. ferruginea in the key in the Pflanzenreich, but the latter has merely stellate indument and poorly demarcated leaf-sheaths. Tillandsia lacera L. B. Smith, sp. nov. Acaulis, florifera 27 cm. alta; foliis mukis, dense rosulatis, erectis, 12-20 cm. longis, utrinque dense adpresseque lepidotis, vaginis late ovatis vel suborbicularibus, atro-castaneis, laminis anguste triangularibus, long acuminatis, 2-3 cm. latis, cinereolepidotis; scapo erecto, gracili; scapi vaginis dense imbricatis, ellipticis, dense lepidotis, infimis foliaceo-laminatis, alteris late rotundatis dein abrupte lineari-caudatis vel apiculatis, ex sicco chartaceis; inflorescentia dense bipinnatim paniculata, breviter cylindrica, 7 cm. longa, 3.5 cm. diametro; bracteis primariis eis supremis scapi similibus, erectis, bases steriles spicarum subaequantibus, spicis e basi sterili nuda erecta divergentibus, dense 4-6-floris, oblongis, acutis, complanatis, 20 mm. longis, 8 mm. latis; bracteis florigeris dense imbricatis, lanceolatis, subcucullatis, 9 mm. longis, sepala paulo superantibus, obtuse carinatis, chartaceis, nervatis, dense adpresseque cinereo-lepidotis; floribus subsessilibus; sepalis liberis, lanceolatis, late acutis, 8 mm. longis, carinatis, nervatis, glabris; petalis 13 mm. longis, auriculis binis praeditis, laminis oblongis, late rotundatis, valde laceratis, fulgide lilacinis, stamina styloque superantibus (Fig. 22, d-f). collected in^thickets along quebrada, above Betania, at base of Paramo de Tama', state of Tachira, alt. 2285-2430 m., July 14, 1944, Julian A. Steyermark 57282. On account of its lacerate auricled petals, Tillandsia lacera is obviously related to T. heterandra, but it differs in its abruptly caudate upper scape-bracts, denser inflorescence, and short spikes with naked sterile bases.
BOTANICAL EXPLORATION IN VENEZUELA - I 151 Tillandsia rubra R. & P. var. reducta L. B. Smith, var. nov. Differt planta minore, 6-10 dm. alta; inflorescentia simplex vel e spica terminal! normal! et lateralibus abortivis formata. Type collected on southeastern portion of base of Carrao-tepui, state of Bolivar, alt. 1460-1615 m., December 4-5, 1944, Julian A. Steyermark 60851 (inflorescence simple); epiphyte on lower part of tree trunk. Also collected on ridge shoulder between Quebrada de Morro and Quebrada Cortijo, by boundary line Lara-Trujillo, above Humocaro Bajo, state of Trujillo, alt. 2600-2800 m., February 6, 1944, Steyermark 55334 (cotype, with inflorescence with aborted lateral branches); epiphyte in crotches of shrub. Tillandsia (Pseudo-Catopsis) stenoglossa L. B. Smith, sp. nov. Acaulis, florifera 3 dm. alta; foliis paucis, subbulbose rosulatis, 26 cm. longis, scapum superantibus, utrinque dense punctulatolepidotis, vivo omnino roseis (ISteyermark), exterioribus valde reductis, vaginis late ovatis, ad 10 cm. longis, laminis anguste lingulatis, 16 mm. latis, apice late acutis apiculatisque, planis; scapo erecto, gracillimo, mox glabro; scapi bracteis oblongis, parvis, remotis, cinereo-lepidotis; inflorescentia erecta, laxe bipinnatim paniculata, 10 cm. longa, spars is sime cinereo-lepidota; bracteis primariis eis scapi similibus, bases breves steriles ramorum paulo superantibus; spicis secunde patentibus, laxe florigeris, 5 cm. longis, 1 cm. latis; rhachi flexuosa, gracili, angulata; bracteis florigeris ovatis, acutis, ecarinatis, quam sepalis distincte brevioribus, fere laevibus; floribus valde divergentibus, nullo modo secundis; sepalis liberis, obovatis, asymmetricis, 5 mm. longis, laevibus (Fig. 23, g-h). Type collected in Bonne tia roraimae forest on southwest-facing shoulder, Ptari-tepui', bordering swamp, state of Bolivar, alt. 2000- 2200 m., November 2, 1944, Julian A. Steyermark 59775. In my key in the Contributions from the Gray Herbarium, 89: 16, this species would fall next to Tillandsia parviflora and T guana eas tens is. It differs from both of them in its ligulate leaf-blades and from 7. guanacastensis in its lax spikes.
