CRESSA L. Sp. PI. 223 (1753). 



Cressa aphylla n. sp. 



From an apparently perennial root ; low, about six inches high, slender, dif- 

 fusely branched from the base ; whole plant covered with scales and 

 appressed hairs ; leafless, each branch subtended by an ovate, acute 

 or acutish bract or scale, smaller ones scattered along the naked 

 branches and at the base of each flowering pedicel ; flowers on very 

 short pedicels ; calyx bibracteolate, the bracts appressed, lanceolate 

 or ovate lanceolate, barely half the length of the calyx ; calyx-teeth 

 oblong-lanceolate, equalling the tube of the corolla; corolla small, 

 yellowish white, its lobes ovate or triangular-lanceolate, pubescent 

 externally, especially at the tip, with white silky hairs; stamens and 

 styles exserted ; upper part of ovary pubescent with white silky 

 hairs. 



A handsome little plant, remarkable for its absence of proper leaves. 

 Ashy in color, due to the scale-like covering and pubescence on the 

 stems. Found on the "Flats" at Corpus Christi, on the east side oi 

 the San Antonio and Aransas Pass Railroad, a short distance beyond the 

 freight station. In March, when the plants were only an inch or two 

 high, they were found infested with a fungus, Aecidium Cressae.

CUSCUTA L. Sp. PI. 124 (1753). 

 Cuscuta arvensis Beyrich; Hook. Fl. Bor. Am. 2: 77 (1834), as 

 synonym. 



In sand on the beach at the Oso, on Lycium Carotinianum, Lepidium 

 Virginicum, and other low plants, growing in a thick, tangled mass. 

 April 12 ("1549), type locality, "N. W. America." 



PHLOX L. Sp. PI. 151 (i753)- 

 Phlox Drummondii Hook. Bot. Mag. 3441 (18 ). 



In rich soil about Kerrville, especially in damp places. A plant col- 

 lected in sand along Nueces Bay, called P. Drummondii villosissima is 

 apparently only a form of the species. When growing directly in the 

 sand it was weak procumbent, with stems almost two feet long and viscid 

 pubescent, but plants growing only a few feet distant in sod, were erect, 

 only three or four inches high and much less pubescent (1435).
