mm. Stylus 4.4-4.7 mm longus. Capsula 1.2-1.5 cm longa loculicida. Semen 

 immaturum 3 x 2.5 mm complanatum marginibus processis corneis rubris ca. 1 

 mm longis dense vestitis. 



HOLOTYPE: Herb with bright red-orange rootstalk, scape apically .brown- 

 orange, perianth basally orange-red and apically white, locally frequent in open 

 savanna of west headland 5 km southwest of cumbre camp, Cerro de la Neblina, 

 Terr. Amazonas, Venezuela, elev. 1900 m, Jan. 6, 1954, Maguire, Wurdack, & 

 Bunting 37108 (NY). Paratype: Rootstalk and inflorescence orange-red, perianth 

 white basally orange, fruit orange-brown, occasional in savanna along west es- 

 carpment 1-3 km north of cumbre camp, Cerro de la Neblina, elev. 1800 m, Jan. 

 10, 1954, Maguire, Wurdack, & Bunting 37222. 



The closest relative of Pyrrorhiza seems to be Scbiekia, which differs in 

 having much smaller flowers with a definitely zygomorphic perianth, one large and 

 two small stamens in the inner cycle, two staminodia in the outer cycle, four 

 (3-5 according to Pax) ovules per locule, a capitulate stigma, and smooth seeds. 



Schiekia orinocensis (H.B.K.) Meissn. subsp. savannarum Maguire & Wurdack, 

 subsp. nov. 



Debilis (ad 40 cm altis) foliis pedunculi reductis, foliis basalibus 3-6 mm 

 latis. 



HOLOTYPE: Fls cream-white, the upper three tepals with basal orange streak, 

 occasional in Savanna No. 1, northwest base of Cerro Yapacana, Terr. Amazonas, 

 Venezuela, elev. 150 m, Dec 31, 1950, Maguire, Cowan, & Wurdack 30496 (NY). 

 Paratypes: Same locality, Nov. 20, 1953, Maguire, Wurdack, & Bunting 36618; 

 Savanna No. 3, northwest base of Cerro Yapacana, elev. 150 m, Dec. 31, 1950, 

 Maguire, Cowan, & Wurdack 30471; Sabana de Moyo on south bank of Rio Ventuari 

 15 km above mouth, Terr. Amazonas, Venezuela, elev. 150 m, May 5, 1954, /. S. 

 Level 37. BRITISH GUIANA: Sand Creek, Rupununi River, Sept., 1948, Wilson- 

 Browne 160; Kwaimatta, Rupununi River, Oct. 1888, Jenman 5164 and idem, Oct, 

 1889, Jenman 5728. Brazil: Rio Caracarahy, Rio Branco, Amazonas, 21-IX-1943, 

 Ducke 1320. 



Subsp. orinocensis has leaves 9-25 mm wide; the scape leaves show much 

 less reduction; and the plant generally is much more robusto 



Dr. Lourteig kindly forwarded from Paris a life-size sketch of Humboldt & 

 Bonpland 843 (Wachendorfia orinocensis H.B.K.), collected on Isla Pararuma, 

 Rio Orinoco, Estado Bolivar, Venezuela. Judging from this drawing, the type of 

 the typical subspecies is rather intermediate between lax woodland forms and 

 the savanna subspecies. However, it tends more toward the woodland collections. 

 The following Terr. Amazonas, Venezuela, collections agree quite well with the 

 Humboldt & Bonpland collection: Maguire 29268, from the Rio Atabapo 15 km 

 above San Fernando de Atabapo, Oct. 17, 1950, and Steyermark 58439, from rock 

 outcrops below the mouth of the Rio Sanariapo, Sept. 18, 1944. The Brazilian 

 and British Guianan specimens cited under subsp. savannarum tend somewhat 

 toward the typical subspecies; a more extreme tending is shown by Tate 20 from 

 Frechal, vicinity of Mt. Roraima, Sept. 6, 1927. 



The woodland form with quite broad leaves is shown in such collections as 

 Spruce 2111 from San Gabriel da Cachoeira, Rio Negro, Brazil and the following 

 Terr. Amazonas, Venezuela, specimens: Maguire & Wurdack 34551 from the wood- 

 land between Savanna No. 3 and the gold mine camp, northwest base of Cerro 

 Yapacana, elev. 150 m, Mar. 17, 1953, and Maguire, Wurdack, & Bunting 37678 

 from scrub forest on Laja Pamoni, Rio Casiquiare at mouth of Cano Pamoni, 

 elev. 130 m, Feb. 12, 1954. Only two marked ecotypes seem involved in the
