NEW SPECIES AND NEW COMBINATIONS IN PAROSELA. 
I have published in previous numbers of the series “ two short pa- 
pers containing many species. There is still a considerable number 
of the so-called Daleas which have not been transferred to Parosela, 
of which some are not known to me. The following list represents 
species which either are new or are old species which I have recently 
studied and believe to belong to Parosela. 
Through the kindness of Col. D. Prain, Director of the Royal 
Botanic Gardens, Kew, and Mr. W. Botting Hemsley I have obtained 
fragments from seven types of Dalea belonging to the Kew Her- 
barium, all but one being of species described by Mr. Hemsley himself. 
Three of these not already transferred to Parosela are here placed 
under that name. 
Parosela anthonyi (Brandeg.) Rose. 
Dalea anthony Brandeg. Erythea 7: 2. 1899. 
Parosela campylostachya Rose, sp. nov. 
Perhaps annual; branches glabrous or nearly so, bearing prominent glands; leaf- 
lets 21 to 45, glabrous, 2 to 3 mm. long, the margins revolute, bearing large glands 
beneath, glandless above; racemes short-peduncled, many-flowered; calyx 10-ribbed, 
glabrous without, bearing | or rarely 2 large glands between the ribs; teeth short 
and broad, hairy within; petals purplish. 
Collected by Dr. C. G. Pringle near Cieneguilla, Oaxaca, November 1, 1894 (no, 
5657). 
Type U. 8. National Herbarium no. 305786. 
This species was originally distributed under the name Dalea nutans, to which it is 
not closely related. It is very near Parosela lasiostoma Rose, but has more numerous 
and smaller leaflets, these more inclined to be revolute. 
Parosela capitata (S. Wats.) Rose. 
Dalea capitata 8. Wats. Proc. Am. Acad. 25: 146. 1890. 
Parosela crassifolia (Hemsl.) Rose. 
Dalea crassifolia Hemsl. Biol. Centr. Am. 1: 238. 1880. 
Parosela hospes Rose, sp. nov. : 
A slender shrub 2 to 3 meters high; branches slender, perfectly glabrous, more 
or less purplish; leaves glabrous throughout; leaflets 5 to 7, oblong to spatulate, 
retuse, sometimes simply rounded at apex, 6 to 10 mm. long, the under surface cov- 
ered with glands, the upper surface simply pitted; inflorescence a weak terminal 
raceme 5 to 6 cm. long; bracts broadly ovate, acute, glabrous, very glandular; 
pedicels short but distinct; calyx tube short, 2 to 3 mm. long, at first very silky 
without, the teeth oval and ciliate, the lower tooth a little longer; petals creamy 
white to pale rose color; stamens 10; ovary somewhat hairy, containing 2 ovules. 
Collected by C. G. Pringle in the Sierra Madre above Monterey, in 1888 (no. 1904, 
type) and 1903 (no, 11417); also by Dr. E. Palmer in the Caracol Mountains, Coahuila, 
in 1880 (no. 210). 
Type U. 8. National Museum no. 24351. 
Dr. 8. Watson in reporting on Dr. FE. Palmer’s plants of 1880 calls this plant a 
variety of Dalea frutescens, but does not give ita name. It differs strikingly from that 
species in several respects. The flowers are in racemes instead of spikes, the calyx
