Phoradendron Tiuallagense Ule, Verhandl. Bot. Verein Prov. Branden- 

 burg, vol. 48. p. 158. 1906. 



Cymosely dichotomous, the moderately long slender branches there- 

 fore with cataphyls on all joints, dioecious?. Internodes moderate (2x 

 40-60 mm.), striate rather than granular, nearly terete but somewhat 

 dilated below the nodes. Cataphyls a single nearly basal pair, triangular, 

 pointed. Leaves ovate-lanceolate, mucronately acuminate to very obtuse, 

 2-2.5x5-6 cm., cuneately subsessile. Spikes solitary, short (10, scarcely 

 lengthening to 30 mm.), with about 4 short joints 4-flowered about the 

 middle when pistillate; peduncle scarcely 2 mm. long. Fruit white, 

 elongated, granular-roughened, 2x4 mm. : sepals erect, somewhat parted.

PHORADENDRON LAXIFLORUM Ule. 



Phoradendron laxiflorum Ule, Verhandl. Bot. Verein Prov. Brandenburg, 

 vol. 48. p. 158. 1906. 



More or less pseudodichotomous or exceptionally cymosely forked, the 

 long slender branches with varying cataphyls, dioecious?. Internodes 

 rather long (2x30-70 mm.), granular, nearly terete but somewhat dilated 

 below the nodes. Cataphyls typically a single nearly basal pair, excep- 

 tionally 3 pairs, and on one shoot absent from two internodes, triangular, 

 keeled and pointed. Leaves ovate-lanceolate, aristately acuminate, 2.5-3x 

 5-7 cm., rather abruptly wing-petioled for scarcely 5 mm. Spikes soli- 

 tary, rather long (25, lengthening to 40-50 mm.), with about 5 very slen- 

 der joints some 10 mm. long 2-flowered near the top when pistillate: 

 peduncle some 3 mm. long, with a pair of scales toward the base. Fruit 

 (immature) subellipsoid, nearly smooth, 3x5 mm. : sepals erect, nearly 

 meeting. Plate 236.

55. CYMOSAE. 



Leaves often comparatively large, drying thin and distinctly pal- 

 mately fine-nerved. Shoots ancipital or terete. Branching cymosely 

 dichotomous, each internode being succeeded by a spike and 2 axillary 

 branches, so that all joints are really basal and hence with 1 or usually 2 

 pairs of cataphyls. Flowers mostly in 6 series. Fruit round, nearly
