98 MR. D. OLIVER ON THE LORANTHACE E. 
The L. diversifolius, Benth. Pl. Hartweg. 63, I am at a loss to 
know what to do with, unless I leave it here for the present. Each 
flower has a small subcupulate bract, which is sometimes reduced 
to a mere ring. 
b. Flores in corymbos v. paniculas cymosas vel racemos compo- 
sitos terminales v. axillares, raro in racemos simplices v. spicas 
dispositi, in speciebus paucis solitarii v. geminati axillares, 
sepius 1-3 unc. longi. 
§ 4. Psittacanthus, Mart., et Tristeryz, Mart. Reg. Flora, 1830, 
15. 17. 
The Eastern species with basifixed anthers included in Tristerys 
and Psittacanthus by Martius are, of course, excluded. As the 
cupule supporting the flower in Psittacanthus, Mart., in many, if 
not in all, cases appears to result from the coalescence of three 
organs, viz. the bract and two bracteoles, I am not able to make 
a separate section of his T'isteryz, in which the bracts are free or 
only partially connate. Loranthus aphyllus of Mr. Miers is very 
near to L. tetrandrus, R. & P., the only species retained in Tri- 
steryz by Blume. The petals are at length usually free. 
-Hab. Mexico, Central America, West Indies, Brazil, Uruguay, 
and Western S. America to Chili. 
III. Flores * subternatim dispositi totidemque bracteis suffulti." 
a. Flores sessiles aut raro subsessiles, sæpius parvi. 
§ 5. Struthanthus, Mart. Reg. Flora, 1830, 102. 
Flowers in terminal or axillary racemes or racemose panicles, 
seldom over 4, rarely 4 in. long. (Euloranthus § Protostelides, 
DC. Passowia, Karst. in Bot. Zeit. 1852, 305.) 
Hab. W. Indies, Panama, Mexico, Guiana, Venezuela, Brazil, 
Uruguay, and Western S. America to Chili. 
b. Flores subternatim dispositi, pedicellati vel centrali sessili, 
singuli 1-bracteati, bractea calycem frequenter superante plus 
minus foliacea raro 0. (Flores in speciebus paucis in racemis 
terminalibus subterni v. alterni bractea cucullari calycem 
sspe superante.) 
§ 6. Tuguana. 
Including the ‘ Oscillanthere Taguane’ of M. DeCandolle, 
referred to Struthanthus by Blume, and Gaiadendron of Don, Gen. 
Syst. iii. 431. They seem to form a distinct natural group with 
terminal inflorescence and rather large flowers.
