M. visciDA, Gray in Bot. Whippl. (Pacif. R. R. Exped. 4) p. 66, 

 in Ives, Colorado Exped. Bot. p. 19. — In addition to the imperfect 

 specimens gathered by CouUer, Bigelow, Newberry, &c., we now have 

 it with both fine flowers and mature fruit, collected by Dr. J. G. 

 Cooper, February 18, 1861, in a gravelly ravine at Fort Mohave. 

 The specimens mostly do not exceed a span in heiglit ; but it is noted 

 that the plant attains the height of two feet. The flower is fully an 

 inch and a half in length. As already stated, I suspect Antirrhimun 

 confertijlorum, Benth., may be founded upon an imperfect specimen of 

 this remarkable plant ; yet the flowers are not subsessile, nor the 

 calyx-segments shorter than the tube of the corolla. 



ToNELLA COLLTNSIOIDES, Nutt., taken up by Benth. in DC. Prodr. 

 10, p. 593, as Collinsia tenella, — having solitary ovules, corolla scarcely 

 gibbous at the base and with an open limb, with the sinuses between 

 the two lateral and the lower (explanate) segment rather deeper than 

 on the posterior side, — may fairly claim the generic rank. Bolander 

 collected it in Mendocino County. 



Collinsia Torreyi: caule tenello ramosissimo superne cum pedi- 

 cellis calyceque glandulosis ; foliis glabris linearibus subdenticulatis 

 basi attenuatis, floralibus superioribus minimis vel obsoletis ; pedicellis 

 quasi verticillato-racemosis calyce duplo longioribus ; calycis segmentis 

 lanceolato-oblongis obtusis coroUfe labiis ina^quilongis plus diraidio 

 brevioribus. — Mariposa, Big-tree Grove, and near Donner Lake, Dr. 

 Torrey. At Clark's Ranch, Bolander. A span high, the cauline 

 leaves 1^ inches long. Verticillastri 4-6-flowered, mostly in a naked 

 raceme. Corolla blue, about as large as in C parvijiora, but the 

 calyx very much shorter, only about one third the length of the lower 

 lip, which moderately exceeds the upper. I name it for the earlier 

 discoverer, that it may be one of the permanent memorials of our oldest 

 active botanist's visit to California, and to the " Mammoth Grove," in 

 the shade of which this delicate little plant grows. 



Collinsia coryjibosa, Hortul. (I know not the origin of the name, 

 which is less appropriate than capitata.wovAd. be), a depressed species, 

 with rounded leaves, almost capitate inflorescence, broad calyx-lobes, 

 and extremely short upper lip of corolla, was collected by Bolander on 

 the coast at Fort Bragg, Humboldt Co. 



Collinsia solitaria, Kellogg, in Proceed. Acad. Calif. 2, p. 10. 

 Depauperate specimens collected by Prof. Brewer, in April, in Marin 

 Co., remarkable for their ovate calyx-lohes, equalling the broad tube of
