CuscuTA Veatchii. Stems slender, branching; scales few 

 and small: flowers few in the clusters, small: calyx narrow- 

 ly campanulate at base, wdth ovate-lanceolate lobes: corolla 

 3 mm. long, twice as long as the calyx, its slender lobes, as 

 w^ell as those of the latter denticulate on the margin and 

 somewhat reflexed-spreading: filaments shorter than the 

 stamens, attached just below the sinus; appendages broad, 

 nearly as long as the tube, fimbriate above: styles 2, short, 

 stout, unequal; stigmas globular; ovules 4. only one appar- 

 ently ever maturing: seed globular; embryo large, solid, 

 globose, minutely tessellated, with a terete curved append- 

 age (radicle ?) scarcely longer than the diameter of the 

 globular portion; albumen apparently none. — Ubi, San 

 Enrique, Santa Maria. 



This very remarkable species of Cuscuta grows upon 

 Vtaiclua discolor, and in the interior, where the tree is taller, 

 frequently covers the whole top with a mass of yellow. As 

 the parasite was often 6-8 feet from the ground, with 

 no intermediate growth, it did not seem that it had germi- 

 nated in the usual way on the earth. Perhaps the very 

 unusual formation of the seed may be intended to furnish 

 support to the infant plant in beginning its growth in 

 a crotch of the tree or a fold of the cracking bark. The 

 specimens were just coming iiito flower, and the descrip- 

 tion of the seed is drawn from such as could be obtained 

 from a dried and persisting tangle of the previous year's 

 grow^th. 



Nicotiana ipomopsifloea Dunal " Tabaco de coyote." — 

 San Gregorio.
