minate, 2} inches long, 1}—13 inches broad, subcoriaceous, slightly 
glossy above, a little paler and with prominent veins beneath, the

long, calyx teeth acuminate ; corolla 2 inch long, three times the length

the throat; lobes 4, the three ventral subequal, the dorsal broader 
emarginate; filaments bearded below; the rudiment one third to one

minate valves at last bifid: seeds separated by hairs. — ‘Tamasop? 
Cafion, San Luis Potosi, June, 1891 (n. 5086). This is an anomalous 
species, sharing almost equally the characters of Pentstemon and 
Russelia. However, its angled stem, short rudimentary stamen, 
cylindrical corolla tube, and the capillary structures between the seeds, 
show apparently a stronger affinity to the latter genus. 
CASTILLEIA PALLIDA, Kunth. var.? ancusTATA. <A span high: 
leaves simple, linear: floral bracts lance-linear, acute: flowers pale 
yellow. — Grassy slopes near Patzcuaro, Michoacan, July, 1892 (n.

Pepicutaris EBURNATA. Rhizome short, knotty: stem erect

pubescent ; of the upper cauline leaves short or none: spike simple, 
more than a foot in length; bracts lance-linear, callous-denticulate
