§ Pseudokrynitzlda, Gray. 



K. racemosa. Eritrichium racemosum, Watson in Gray, Proc. Am. Acad, 

 xvii. 226; Krynitzkia ramosissima, Gray 1. c. xx. 277, in part, must re- 

 tain its specific name, which, for the plant described originally, can 

 hardly be considered inappropriate. 



The calyces are on pedicels as long as themselves, at 

 least, and the species is a suffrutescent Pseudokrynitzlda, 

 whose nutlets are light gray and muriculate, extremely un- 

 like those of the annual Eukrynitzkias, which I have distin- 

 guished on page 203, preceding. 



Convolvulus luteolus, Gray. 



It is this species, and not C. occidentalis, which has the 

 shrubby character described in Bot. Gaz. vii. 93. The 

 following is entirely distinct from it. 



Convolvulus fulcratus. 



Only a foot or two high, not shrubby, feebly, if at all 

 twining, soft-pubescent throughout : bracts foliaceous, and, 

 like the leaves, sagittate : corolla pale yellow : capsule and 

 seed not seen. C. luteolus, var. fulcratus, Gray, Bot. Cal. i. 

 534; Syn. Fl. ii. 216. 



Foothills of the Sierra, from the central parts of Califor- 

 nia down to the peninsula, where it has lately been col- 

 lected by Mr. Cleveland. Remarkably unlike the tall, 

 woody climber with perfectly glabrous foliage, and small, 

 almost subulate bracts; and there are no intermediate forms. 



Convolvulus macrostegius. 



Suffrutescent, the trailing or climbing stems, with their 

 herbaceous flowering branches 6 — 15 feet long: glabrous 

 throughout: leaves triangular-hastate, 2 — 3 inches long, and 

 as broad at base, on petioles of about the same length: ped- 

 uncles 6 — 8 inches long, usually 3-flowered, a pair of large, 

 loose membranaceo-foliaceous bracts inclosing all the buds, 

 the lateral flowers each similarly bracted within the outer
