CEANOTHUS COLLINA. 



{Mountain Ceanothus.) 



NATURAL ORDER. 

 RHAMNByE. — (E. Brown, Gen. Rem. p. 22.) 



GENERIC CHARACTER. 



Ceanothus (Lin. gen. 267). Calyx 5-fidus campanulatus, post anthesin medio circumscissus, 

 basi sub fructu persistente, sub-adhserente. Petala 5 parva longe unguiculata fornicata rarius 0. 

 Stamina exserta, ante petala. Styli 2-3 ad medium coaliti. Bacca exsucca 3-locularis (rarius 

 2-4-loc), cocculis cbartaceis 1-spermis basi perviis latere interiore dehiscentibus. Semina ovata 

 sulco destituta. — Be Cand. Prod. vol. 2. p. 29. 



Calyx with five divisions bell-shaped, after flowering cut round in the middle, remaining at 

 the base under the fruit, somewhat adhering. Petals 5, small, longly clawed, arched, rarely 

 wanting. Stamens protruding, before the petals. Styles 2 to 3, joined at the middle. Berries 

 juiceless, 3-celled (rarely from 2 to 4), the papery cells one-seeded, bursting by openings at the 

 base on the interior. Seeds ovate, without a furrow. 



SPECIFIC CHARACTER. 



C. Collina (Douglas). Ramis decumbentibus teretibus sub-glabris ; foliis ovatis vel elliptico- 

 ovatis subviscosis glanduloso-serratis superne nitidis, subtus pilis adpressis 3 nerviis ; stipulis 

 setaceis ; paniculis axillaribus. 



Descr. — Branches drooping, round, somewhat smooth ; leaves ovate or elliptical-ovate, 

 somewhat clammy, glandular-serrated, upper surface shining, under surface covered with 

 appressed hairs, 3-nerved ; stipules awl-shaped ; panicles axillary. 



This is a low decumbent shrub, its trunk scarcely rising a foot from the 

 ground ; yet, being an evergreen, and perfectly hardy, it is a plant well worthy 

 of notice, and will make an interesting addition to the shrubbery. It flowers 

 freely ; the plant from which our drawing was made having flowered twice during 

 the past summer. We have not perceived any fruit at present, but probably that 

 will be produced (as by many other North American species) when the plant 

 becomes older. Although it cannot be considered showy, yet it may vie perhaps 

 with many of the hardy species at present in cultivation. We except, of course, 

 the truly beautiful species C. azurea; which, however, can scarcely be considered 

 hardy, having only succeeded (as far as we know) in sheltered situations. It 

 is moreover entitled to particular notice from the remarkable circumstances
