ceolees (tres-rareruent ovales), pointues deiitelees, glabres anx deux faces. 

 PauicT;les simples on pins ou moins rameuses, laches, subthja-sifoiines, 

 raccoiircies, glabres. — Sons-arbrisseau haut de 1 a 2 pieds. Tiges roiigeatres, 

 tres-glabres, ordinairemeiit rainetises. Fenilles d'uu vert gai, un peu 

 hiisantes eu dessns: celles des rameaux lateraux longues d'environ 2 

 polices, sur 6 lignes de large; celles des tiges quelquefois larges d'unpouce. 

 Fleurs blanches, on, roses on blauchatres, phis petites que dans les especes 

 precedeutes. Fruit semblable a celui du Ceanot glahre. — Cette espece, 

 sans doute indigene dans les Etats-Unis, se cultive assez souveut dans les 

 jardius. Les varietes a fleurs roses ou bleufttres, encore peu repandues, 

 nieritent toute I'attention des amateurs, car elles sont d'un fort bel effet. 

 Elles ont ete obteuues par MM. Baumanu a Boll wilier, de graines du type 

 del'espece.— Spach. Hist. Nat. des Veget, ii, 460 (1834). 



Ceanoihus Neumannl. Tausch Dendr. ex. -boh. exs. : foliis ovatis serrul- 

 atis 3-nerviis sub-pubescentibus, thyrsis axillari-terminalibus subcorym- 

 bosis, in corymbum densum congestis, capsulis congestis rugosis 3-carina- 

 tis (majoribiis). — In hortis promiscuus cum C. americauo L. obveuit, qui 

 diflfert thyrsis oblongis in paniculam dispositis, capsulis lasvibus multo 

 miuoribus non subulato carinatis. In botauicis indefesso et amicissimo 

 Neumann primam hujus speciei cognitionem debeo. — Flora, xxi, 1838, 738. 



Ceanothiis collinus. In the nursery of Messrs. Low & Co. this pretty 

 species is at present blooming. * » * jts ovate deeply furrowed and 

 serrated leaves are of a very symmetrical character and the flowers, which 

 appear in terminal thyrses like those of C. azureiis. are pure white. — 

 Paxton Mag. of Bot. vi, 140 (1839). 



Ceanothus j^allidus ; caule arborescente ramis ramulisque j^ubescentibus 

 teretibus, foliis triplinerviis ovalibus serratis supra glabris nitidis subtiis 

 viridibus pubescentibus, floribus thyrsoideo-iianiculatis: pedicellis capi- 

 tato-corymbosis pilosis. — This plant occurs in the gardens under the 

 )iame of Ceanothus ovatus and thyrsiflorus, from both which it is certainly 

 distinct. The first is a mere variety of Ceanothus Americanus, and the 

 latter is a Calif ornian tree with deep-blue flowers and very strongly angu- 

 lar branches. It approaches more nearly to the lovely C. azureits, but its 

 leaves are green, not hoary beneath, and the flowers are smaller as well as 

 much paler. If it were probable that such a thing would happen, this 

 might be suspected to be a cross between C. azureus and Americanus. — 

 It is a beautiful shrub and much hardier than Ceanothus azureus; during 

 the summer and autumn mouths it flowers freely, if trained to a wall with 

 a south aspect. — It strikes readily from cuttings of the half-ripened wood 

 during autumn, and grows well in any soil, if not too poor or too wet. 

 The accompanying figure [flowers pale lilac] was taken from a plant in 

 the garden of the Horticultural Society, which was presented by the 

 Messrs. Baumanns, of Bollviller, tinder the name of Ceanothus ovatus. — 

 Lindley, in Bot. Eeg., vol. xxvi, 20, pi. 20 (1840).
