brevioribus corolla lutea vix brevioribus ; galea recta tubo cequilonga, 

 labio brevissiino. — On the Mohave Desert, S. E. California, May 18, 

 1882, Prinyle. Remarkable for the anterior and posterior calyx- 

 lobes. 



ORTnocARPUS IMBRICATUS, Torr. in Watson. Bot. King, 458, is a 

 good species and was very wrongly referred to 0. (enuifolius, Benth. 

 in Syn. Fl. 300. It was characterized on poor specimens, which 

 seemed to have a minutely uncinate ti[) to the galea ; this, however, 

 the numerous specimens now in hand do not have.* 



CoUDYLANTHUS Pringlei. Adenostejia/iutL'r Ti-trastemones oUgo-

 also in the foliage) is e.xhibited by no. 3255 coll. Spruce on the Oronoco, distrilj- 

 uted by Bcntliani as " Z>. elomjatu," but its calyx appears to be quite glabrous. 



* * Corolla-tube quite glabrous : stem very slender : leaves all narrow linear to 



filiform. 



B. Mexicana, Ilcnisl. Bot. Biol. Ccntr.-Ain. ii. 457. Rather tall : tube of the 

 corolla rather conspicuously exsertod ; the expanded limb a third to a halt inch 

 broad: calyx-teeth slender-subulate, in fruit spreading. — N. W. Jlcxico, See- 

 mnnn. Mexico, Jlartwe;/, 100 (referred to />. lil/io^pirmifolia, in Benth. PI. Ilartw., 

 and by Ilemsley) ; Orizaba, Botteri, 583, 794, form with smaller corolla. 



B. DiSTicn,\, IIBK. Nov. Gen. & Spec, ii .340, ex char. Very slender: leaves 

 mostly filiform: flowers small: tube of corolla less exsertetl : calyx-teeth 

 shorter, triangular-subulate, erect or little spreading in fruit. B. tinctoria, 

 Bertol. Fl Guatcmai. 42G ? — S. ]\Iexico, (Jliiishrcfj/d, 82C0. The original habitat 

 Santa Fe de Bogota? The plant here taken for this species was coUectetl in 

 that district by Ilolton, 585; also Venezuela, Fcndlcr, 848. 



* The three species of the first division of true Onhocarpus, in Syn. Fl. N. 

 Amer., are better characterized as follows : — 



•*- Corolla and bracts rose-purple or purplish ; the latter whollj' chartaceo- 



scarious and reticulated in age. 

 O. iMHRiCATUS, Torr. 1. c. Usually slender and branched from the base; 

 stem and leaves minutely puberulent : the rounded bracts either naked or 

 sparsely ciliate at base, entire or usually with a single pair of short small lobes : 

 calyx very short, its broad lobes with a pair of short and small subulate teeth: 

 corolla hardly half inch long; lip and galea of equal length ; the latter usually 

 quite destittUe of uncinate apex : anther-cells oval. — 0. lennlfolius maiidy. Gray, 

 Bot. Calif i.*577, partly, Syn. Fl., mainly. — Common in the mountains of the 

 northern part of California and adjacent part of Oregon.
