 A common and very polymorphous species, which runs into the following principal 

 but indejinite varieties. 



Var. puniceus, willi red or scarlet flowers on mostly slender peduncles : lobes 

 of the corolla simj)ly obcordate or eniarginate, or sometimes irregularly toothed : 

 calyx glabrous. — Diplacus puniceus, Nutt. 1. c.; Hook. Eot. Mag. t. 3G65. J), 

 glutinusus, var. puiiiceuti, Uenth. in DC 



Vur. linearis, witii red-brown or sulmon-coloreil llowors on very short pedun- 

 cles: calyx commonly pubescent: leaves linear and with nearly entire soon revolute 

 margins, more rigid. — M. linearis, lienth. Scioph. Ind. 27. Diplacns leiAanthus, 

 Nutt. 1. c. 



Var. brachypus, with salmon-colored flowers of pretty large size (fully 2 inches 

 long), on very aliort peduncles : calyx viscid-pubescent or villous : leaves linear- 

 lanceolate, entire or nearly so. — Diplacus lonyijiorus, Nutt. 1. c.

 ornanientul in luillivation, especially .;h ii green-liouse plant : llowering almost tlirou^'h the year. 

 Kven in tlio wild state it exliiliits a great diversity of colors ; but it seems imiiossiWc to distin- 

 guish the loniis as sjieeies. The last variety eolJeeted by Coulter (No. &M), near Santa Barbara 

 by Nutlall, and a form of it, eonue.;tiii<; with ordinary .")/. yluiinusus, in San J-uis Oliispo Co., 

 by Brewer. 



§ 4. Corolla iiriih short and included proper tube: calyx ivith plaited-carinate salient 

 angles, 5-toothed, the strong nerve traversing the teeth: style glabrous: stigma 

 2-lippe(l, the li]is, ovate or roundish and equal : placentit remaining united in 

 the axis of the capsule, or dividing merely at top (in M. rubellus sometimes 

 completely) ; the. thin and often membranaceous valves tardily separating from 

 the axis : annual or perennial herbs. — MlMULUS proper. 



* Large-flowered : corolla 1 |^o 2 inches long, red or rose-color, with cylindrical tube 

 and throat longer than the limb : calyx oblong-prismatic ; the short teeth nearly 

 equal : anthers hairy or nearly glabrous in the same species : peduncles elongated : 

 seeds ivith a loose dull epidermis wrinkled lengthwise : leaves several-nerved f rum the 

 base : root perennial. 



12. M. cardinalis, Dougl. Villous with viscid hairs: leaves ovate and the 

 upper often connate, the lower commonly obovate-lanceolate, all erosely dentate : 

 corolla scarlet, witli tube hardly exceeding the calyx ; the limb remarkably oblique, 

 the upper lip nearly erect with the lobes turned back, the lower reflexed : stamens 

 projecting. — l.indl. in Ilort. Trans, ii. 70, t. 3 ; J)rit. Fl. Gard. ser. 2, t. 358 ;

Common along water-couises throughout the State and in Oregon ; much prized in cultivation. 

 Capsule oblong, tluu-chartaceous when dry ; the valves tardily separating from the placenta- 

 bearing a.xis. 



13. M. Le"wisii, Pur.sh. More slender than the foregoing, greener, minutely 

 somewhat viscid-pubescent : leaves from oblong-ovate to hmceolato, merely denticu- 

 late : corolla rose-red or jialer (the throat spotted witli yellow) ; its tube longer than^ 

 the calyx ; the roundish lobes all si)reading : stamens included. — Pursh, Fl. ii.
