 thin texture, IV2 to 2 lines long, borne in loose racemose panicles; calyx very .short, 

 forming a shallowly lobed saucer at base of corolla, the lobes broadly triangular- 

 ovate, more or less acute; tube of corolla gradually widening upwards, deeply 

 campanulate, lobes short, shorter than the tube, erect or slightly spreading, with 

 inflexed acute tips; scales large, fringed; anthers not purple; capsule ovate or sub- 

 globose, thickened at the apex and somewhat pointed, enclosed by the distended 

 corolla. 



Native of South America, spreading almost throughout the world in seed of 

 Medicago sativa : occurring in California at scattered localities, 10 to 2000 feet.

6. C. arvensis Beyrich. Field Dodder. Stems rather fine, pale; flowers small, 

 occasionally with lenticel-like glands, sessile or nearly so in dense globose clusters 

 1/2 inch thick; calyx-lobes obtuse, broad, about equaling tube of the corolla; corolla 

 1 line long, with acuminate lobes and short broad tube, in age remaining at base of 

 capsule; scales often exceeding the tube and deeply fringed; capsule depressed- 

 globose, with a distinct central pit; seeds 2 or 4. 



Mostly moist or wet stations, 10 to 3500 feet : widely distributed and found in 

 all continents. In our region it is common on Xanthium canadense and Trifolium 

 pratense. Apr. -Sept. 



Tax. note. — The name Cuscuta arvensis Beyrich (Engelm. in Gray, Man. ed. 2, 336,- — 1859) 

 would appear to have been as well published as names of numerous other early species which are 

 still accepted. That Engelmaun included with it his C. pentagona, now regarded as distinct, does 

 not invalidate C. arvensis according to common practice. There are very many old or Linnean 

 species whose names still hold, even though the original group has been subject to subsequent 

 segregation. Eugelmann's Cuscuta arvensis as a name is not revertible, because the Cuscuta ar- 

 vensis published in Hooker's Flora Boreali-Americana (2:77, — 1840) is a nomen nudum. If a 

 nomen nudum is of no effect (since without description), then logically it is as if never published. 

 It is, therefore, illogical to treat the name in Hooker's Flora as of no effect, and at the same time 

 having effect, namely, that it has the power to run against a later homonym. Therefore, t!ie name 

 C. campestris Yuncker is not used here. So far as Beyrich is concerned, he himself never pub- 

 lished C. arvensis and his herbarium use of the name for a specimen of another species (to which 

 appeal has been made) is of no moment under the International Eules. No part of the decision 

 in determining the identity and proper name of a species has ever legally rested on an herbarium 

 specimen under any section of the International Rules of Nomenclature. Which means, in this 

 case, that a specimen or a manuscript herbarium record cannot be used to cancel a printed pub- 

 lished description in whole or in part.
