Heller: plants of the Hawaiian islands. 817 



LORANTHACEAE. 



VISCUM L. Sp. PL 1023. 1753. 



All of the Hawaiian species belong to the section Aspiduxia, 

 which is leafless, and perhaps should represent a distinct 

 genus. 



Yiscum articulatum Bdrm. f. PI. Ind. 311. 1768. 



If true Viscum articulatum, or any other of the species men- 

 tioned in DcCandolle's Prodromus, occur in the Hawaiian Is- 

 lands, the species with flat and rather broad joints, which I 

 found growing only on JElaeocarpusbifidus and on the island of 

 Oahu, is apparently referable to it (2212). 



To this also must be referred two forms somewhat dissimilar 

 in habit, No. 2183, found growing on the "Ohia ha," or Eu- 

 genia sandwicensis, is erect, with slender branches, the joints 

 slightly contracting at the base, or of an equal width through- 

 out, the ultimate segments inclined to be pointed. Collected 

 on Konahuanui, Oahu, at an elevation of about 2700 feet. 



On the island of Kauai, on the main ridge west of the Hana- 

 pepe river, at about 3500 feet elevation, and on Kaholuamano 

 above Waimea, at 4000 feet, occurs a distinct form (2680), much 

 resembling V. attenuatum DC. The branches are lax, droop- 

 ing, spreading, and rather weak. The joints are elongated, 

 narrow, and of an almost even width throughout. The ulti- 

 mate segments are also somewhat pointed. It grew in dense 

 clusters on the branches of Elaeocarpus bifidus. On Kaholua- 

 mano it is quite common. The tendency to become disarticu- 

 lated while drying is very slight in this form. 



Viscum pendulum (Wawra). 



Vicum moniliforrm Blumb, var. p< ndula Wawka, Flora (II) 

 ;j 1:140. 187.3. 



The pendulous habit and large size at once distinguish this 

 from all the other forms. It seems to be Hillebrand's Viscum 

 articulatum var. beta. In the mature plants the joints are an 

 inch or more in width, and not contracted at the point of articu- 

 lation. In dried specimens, however, the joints shrink consider- 

 ably. Collected on Kaholumano, above Waimea, Kauai, at an 

 elevation of 4000 feet. It was noticed only on an apparently 

 undescribed species of Pelca. which grows near streams in the 

 forest. 



September to October (2810); from near the original local 

 ity, "Kauai, um Halemanu."
