2. L. spinosa, var. cladopappa, Gray ; a state with many of the stiff bristles 

 of the pappus bearing a few slender branches toward the base. 



Carson Valley, Lcmtnon, 1875. Specimens by other collectors from the same neighborhood do 

 not show this peculiarity of the pappus, hi which, as well as hi the rigidity, there is an approach 

 to C/uchulclpluz. 



Page 442. 123. LACTUCA. 



Lactoca Canadensis, Linn., was collected in a grain-field in Sierra Valley, in the summer of 

 1875. Being otherwise unknown west of the Rocky Mountains, it was probably a waif or chance- 

 comer.

* Capsule short, 2-celled, 2-valved at the top. 



1. Lobelia. Corolla with the more or less elongated tube split from top to bottom on the appar- 



ently upper side. Stamens free from the corolla. 



2. Palmereila. Corolla with along tube, which is entire at the summit; the stamens adnate 



to its upper part. 



3. Laurentia. ( lorolla with a rather long entire tube ; the stamens free from it, except perhaps 



at the very base. 



* * Capsule and ovary long and linear, one-celled, opening down the sides. 



4. Downingia. Corolla with a very short and entire tube. 

 Prefix no. 5 to Nemacladus. 



1. LOBELIA, Linn. 



Calyx 5-cleft, and with a short tube. Corolla with a straight tube split down t<> 

 the base on one (apparently the upper) sid| ; the two lubes on that sideereet or more 

 separated &om the three more united oils; all the petals sometimes inclined to 

 separate at tin- base. Anthers and all the'; pper pari of the filaments united around 

 the style : these inserted with the corolla] Stigma 2-lobed. Capsule 2-valved al 

 the top. Seeds very numerous and small — Chiefly herbs, id' wide geographic al 

 distribution ; with racemose or spicule lluwis, produced in summer. 



1. L. splendens, Willd. < Uabrous or I arly so : simple stem 2 or 3 fed higli : 

 leaves linear-lanceolate, glandular-denticuht : raceme naked, many-flowered ; tube 

 of the calyx hemispherical ; its lobes sleneerlv linear-subulate: corolla intense red, 

 an inch long; its lobes (in our plant) only Jill' the length of the tube : two of the 

 anthers strongly bearded at the tip. — Mori Berol. t. 86. 



Mountains northeast of San Diego, Cleveland, turner. Extends through Arizona to Texas and 

 Mexico, probably only in shaded and uieist or wctplaces. Much resembles the eastern /.. cardi-

 the wild Mexican specimens. 



2. PALMERELLA, Gray.

the lobes slenderly linear-subulate. Corolla vith its long and straight narrow-c\ lin 

 drieal tube, entire (al leas! the uppi i pai i il al ill lilated al the throal ; the-shorl
