capitate, ovate or conic stigmata. The species of this group, 
modifications in the form of the stigma ae the dehis- 
cence of the capsule furnish the basis for a further subdivision 
of the three principal groups. I will here only say, that _in

The following sections are preipanedi 
A. Cuscuta Group. 
1. Evcuscura. . Bivias nearly as long or longer and us thick or thicker 
than the filiform stigmata ; capsule regularly circumscissile. 
2s er _Subulat mi bese nearly ee capsule opening trans- 
without a regular jo tion. 
3. S seiaies. Subula te styles longer than the short subulate stigma- 
ta; capsule baccate. 
4. PacHYsTIGMA. “Cylindric or oblong stigmata thicker than the filiform 
styles ; capsule bursting transversely. 
B. Grammica Group. 
5. Everammica. Stigmata capitate ; capsule more or less irregularly cir- 
cumscissile. 
6. CristoGRamMica. Stigmata capitate; capsule baccate 
ye Lopoeriaus: Top of clavate styles lobed at the upper stigmatose sur- 
C. Monogya Group. 
MonocYnevia. Stigmata capitate or ovate, united, or distin:

See. 1. Hueuscuta. 
Styles filiform, terminating in filiform stigmata of the same 
length or shorter, rarely longer, and of the same thickness as 
the styles, or thinner rill 2 da end. Capsule regularly cir- 
cumscissile “3 a joint, the rab of cS haat being thickened. 
Usually all four seeds ripen; they are triangular, with an ob- 
bags & truncate base, the hilum forming a narrow perpendicu-
