nearly sessile, somewhat clustered ; calyx persistent, 4-5-cleft ; stigmas 3. — 

 Hook. ! ic. fl. i. 287. 



Texas, Drummond f — Branches rigid, flexuous, grayish. Leaves about 

 an inch long. Flowers in small axillary fascicles. Drupe the size of a 

 pepper-corn, on very short pedicels. — Very different from C. microphylla; 

 tJie leaves very much larger, and not cus])idate, the pedicels very short, &c. 



4. CEANOTHUS, p. 264-268. 



1. C. Americanus y. — Excl. syn. C. ovatus, Desf. 



2. C. ovalis, — To this belongs C. ovatus, Desf. ! which is the prior name, 

 but less appropriate, as the leaves are never ovate. 



5. C. velutinus (Hook. !) — Add var. 



0.1 leevigatus: leaves glabrous beneath. — C. Isevigatus, Hook.! fl. Bor.- 

 Am. 1. p. 125. (Nootka, Menzics !) This was omitted by accident. — The 

 following may stand between this and C. incanus. 



5 (a). C. sorediatus (Hook. & Arn.) : branches terete, verrucose with 

 resinous dots ; branchlets spreading, somewliat silky ; leaves elliptic-ovate, 

 obtuse, somewhat coriaceous, glandular-denticulate, 3-ribbed, glabrous above, 

 canescent beneath, silky on the veins ; clusters many-flowered, dense, 

 scarcely longer than the leaves (flowers blue). Hook. S^- Am.! hot. Beechey, 

 suppl. p. 328. 



California, Douglas ! — Ovary without lobes. 



12. C. divaricatus. — Add syn. Hook. Sf Am.! hot. Beechey, suppl. p. 

 328. — Branches terete, often pruinose ; panicles elongated and spicate-race- 

 mose, densely flowered. (California, Douglas ! and Snake Country, Mr. 

 Tolmie !) — Tlie specimens are much more complete than those of Mr. 

 Nuttall, and Hooker has properly amended the specific character. In some 

 cases the leaves are rather conspicuously serrulate. 



12 (a). C. integerrimus (Hook. & Arn.) : glabrous; branches somewhat 

 angled, slightly resinous-viscous ; leaves 3-ribbed, rather membranaceous, 

 oblong-elliptical, obtuse, entire, paler beneath ; panicles elongated, many- 

 flowered ; flowers glomerate, white. Hook. S^- Am. I. c. p. 329. 



California, Douglas! — Panicles very long and narrow. Plant entirely 

 glabrous, except the very youngest leaves or branches. Ovary without pro- 

 jecting lobes. Hook. 4* Am. 



14. C. cuneatus. — Vid. Hook. S^' Arn. I. c. for remarks in confirmation of 

 our own suggestions respecting this and the following species. (California,

19. C. papillosus. — Add syn. Hook. Sf Am. ! I. c. ; Hook. ic. pi. t. 272.
