Mr. Bentham, who was the first to study the species, took the specimens for a de- 
formed Gaura, and commented on them as follows: ! 
“In all specimens there is the same semiarticulation and thickening of the flowering 
part of the branches so as to enclose the ovaria, which Chamisso and Schlechtendal 
observed in an allied Mexican species, and which appeared to them to justify the 
constituting a distinct genus under the name of Gongylocarpus. It is, however, 
much more probably the effect of some disease or parasite. I could not indeed, any 
more than the above quoted authors, discover any traces of fungus or insect, but the 
distortion of the ovaries, as well as of the more enlarged capsules and seeds which 
may be found still remaining in their hardened state in the old woody branches, 
show that this is not the healthy natural form of the plant. The flowers appear in all 
other respects perfect, and are evidently showy.”’

1. Burragea fruticulosa (Benth.) Donn. Smith & Rose. 
Gaura fruticulosa Benth. Bot. Voy. Sulph. 15. 1844. 
Gongylocarpus fruticulosus T. S. Brandeg. Proc. Calif. Acad. II. 2: 158. 1889. 
A low, bushy plant, 30 to 60 cm. high; young branches purple, covered with short, 
spreading, glandular (?) hairs; leaf branches often short and stunted, showing numerous 
closely set leaf scars; leaves numerous, often closely set, on vigorous branches more 
remote, linear, 2 mm. broad, entire, acute, slightly narrowed at base, not perceptibly 
veined, glandular-pubescent; calyx tube slender, 15 mm. long, the segments oblong, 
pointed, 7 mm. long, becoming reflexed; petals obovate, about 7 mm. long. 
TYPE LocaLity: Magdalena Bay, Lower California. 
Collected on Santa Margarita Island, Lower California, March 19, 1911, by J. N. 
Rose (no. 16284). 
Bentham evidently had both species of Burragea in his Gaura fruticulosa, for he says 
that some of the specimens are glabrous and others are pubescent. The pubescent 
form has been selected to serve as a type for Bentham’s species. Both species grow 
about Magdalena Bay, but, so far as observed, not together. . 
2. Burragea frutescens (Curran) Donn. Smith & Rose. 
Gongylocarpus frutescens Curran, Proc. Calif, Acad. II. 1: 231. 1888. 
A low, widely spreading shrub, rarely over 30 to 60 cm. high, glabrous throughout, 
with numerous short branches, the young ones dark purple; leaves alternate, narrowly 
oblanceolate, often 7 mm. broad, 3 cm. long, thickish, the midvein indistinct; calyx 
tube 2 to 2.5 cm. long, petals 12 mm. long; fruiting branches thick, 1 to 10 cm. long, 
turgid, purple, at first leafy but becoming naked. 
TYPE LOCALITY: Magdalena Bay, Lower California. 
Collected also on the shore of Santa Maria Bay, Magdalena Island, Lower California, 
March 18, 1911, by J. N. Rose (no. 16263). 
NOTE. 
While reading the final proof of this paper, our ajtention was called to two species, 
one with two varieties, just described by T. Loesencr in Fedde, Repertorium Spe- 
cierum Novarum Regni Vegetabilis, volume 12. These are based on the same collec- 
tions which we have studied and, being clearly synonyms, are so referred. Two 
names, H. hemsleyana and H. pedicellata, also are mentioned, but doubtless have not 
been published.
