Parva, e fragmentis solum cognita; foliis ca. 2 dm. longis, vaginis brevibus, quam laminis viz latioribus, atro-castaneis , laminis anguste triangularibus, acuminacis, pungentibus, planis, ad 28 mm. latis, integerrimis, supra glabris lucidisque, subtus subdense punctulato-lepidotis, utrinque viridibus; scapo erecto, 6 mm. diametro, dense brunneo-puberulo; scapi vaginis anguste triangularibus, acuminatis, glabris, ad apicem versus incrassatis, supremis quam internodiis bene brevioribus; inflorescentia subdense tripinnatim paniculata, 25 cm. longa, 15 cm. diametro, bracteis primariis exceptis dense puberula; bracteis primariis eis scapi similibus, ad 18 mm. longis; ramis gracilibus, sublaxifloris; bracteis florigeris e late ovato acuminatis, quam ovariis subduplo brevioribus, tenuibus; floribus sessilibus, divergentibus vel patentibus; sepalis oblongoellipticis, obtuse carinatis cucullatisque, 4 mm. longis; petalis oblongo-ellipticis, obtusis, sepala subaequantibus, albis; staminibus liberis, inclusis; ovario 5-6 mm. longo, tereti, paulo supero; stylis liberis (Fig. 19, f-k). Type collected on ridge top, summit of Cerro Duida, Savanna Hills, Territorio Federal Amazonas, alt. 1025-1200 m., September 2, 1944, Julian A. Steyermark 58279. For comparison with other species see the key below. The following key will serve to relate the new species of Brocchinia, proposed in this paper, to my treatment in the Contributions from the Gray Herbarium 161: 30. 1946. 1. Ovary only one-third inferior; leaves and scape-bracts serrate. 1. Ovary wholly or almost wholly inferior. B, s errata. 2. Leaf-blades narrowly triangular or subtriangular, acute or acuminate. 3. Capsule trigonous. 4. Flowers sessile; petals orange B. Steyermarkii, 4. Flowers slenderly pedicellate. 5. Leaf-blades, scape-bracts and primary bracts of uniform texture; inflorescence bipinnate B, prismatic a. 5. Leaf-blades, scape-bracts and primary bracts with dark castaneous indurate involute apices; inflorescence tripinnate fl, melanacra, 3. Capsule terete. 6. Leaf-sheaths prominent, 20-25 cm. long, dark castaneous; inflorescence narrow B. ocuminata. 6. Leaf-sheaths inconspicuous, much smaller; inflorescence broad.

Leaf-blades ligulate, rounded and apiculate (no new species under this heading). Connellia caricifolia L. B. Smith, sp. nov. Caulescens, ramosa, florifera 17 cm. alta; caule ultra 1 dm. longo, 2-3 mm. diametro; foliis dense quaquaversis, 6 cm. longis, omnino inermibus, vaginis late ovatis, 2 cm. longis, glabris, sulcatis, laminis linearibus, 4 mm. latis, supra glabris, subtus perobscure punctulato-lepidotis, marginibus albis cartilagineis except is utrinque viridibus; scapo erecto, 2-2.5 mm. diametro, brunneo, lucido; scapi bracteis internodia superantibus sed scapum baud obtengentibus, late ovatis, lucidis, infimis caudatis; inflorescentia simplicissima, laxe perpauciflora, glabra; bracteis florigeris late ellipticis, apiculatis, ad 14 mm. longis, pedicellos graciles superantibus; floribus erectis; sepalis ellipticis, ca. 12 mm. longis, tenuibus; petalis 2 cm. longis, unguiculatis , roseis, lamina suborbiculari; staminibus styloque inclusis; ovario supero (Fig. 20, a-b). Type collected on exposed surface of morros, summit of Mount Roraima, on northwest portion north and northwest of Summit Camp, state of Boh'var, alt. 2620-2740 m., September 27, 1944, Julian A. Steyermark 58846. The flowers are very similar to those of C f Quelchii, also from Mount Roraima, but the leaves are weak, glabrous above and prominently white -margined where those of C. Quelchii are stiff, densely lanate above and essentially uniform in texture. With considerable misgiving I am restoring the genus Connellia, because it represents the least objectionable of several awkward choices. To include C. Augustae, C Quelchii and the two new species here proposed, in Puya, involves too much contradiction in the key to genera. The technical characters of capsule-dehiscence and seed-appendages place Connellia much closer to Lindmania than to P uya which it more closely resembles in habit. To reduce Connellia to Lindmania would be logical, especially in view of the intermediate position of Lindmania guianensis, but I hesitate to do so until it is possible to establish the validity of Lindmania as distinct from the earlier Cottendorfia. Lindmania guianensis has the placentae practically as reduced as in Cottendorfia, and the discovery of fruit of the latter may show that the rather doubtful distinction on ovule-appendage is equally untenable. Phylogenetically, Connellia appears to link Puya to Lindmania but to be closer to the latter.
