4. Cr. Aparine, l.iim. Stem weak and spvoadiiig : leaves mostly in eij^hts, 

 liiioar-ul)laiic(H)iali) ; tliu mav[j[ius, midrili, ami angles of tlie branches anneil witli 

 snreailing or retrorsc spinuloso bristles : peihnuiles elongated, 1 — 2-llo\vered : corolla 

 greenisli-whito : Iriiit rather large. 



Moist grounds, apparently throughout the State, and without doubt a native plant ; but only 

 in the smaller form (var. minor, llook.) : the leaves barely an inch or thereabouts in lengtli, 

 whereas in the ordinary eastern and European plants they are of twice that length, and the liiiil 

 larger.

5. Gr. aspeiTimuni, ^Imy. J)iiriisely much branched, weak: the branches 

 slender, minutely and retrorsely spinulose : leaves in sixes, lanceolate or the lower 

 oblanceolate verging to oblong, tipped -with a slender cuspidate point, smooth ami 

 shining both sides, the margins and midrib beneath thickly and retrorsely spinu- 

 lose-ciiiate : llowers numerous, in naked cymes tenninating the branchlets : pedun- 

 cles and pedicels lilil'orm : lobes of the ap[)arently greenish-whito corolla ovate and 

 ucuto : immature fruit muricate granulate. — I'l. Feudl. GO, ^ I'l. Wright, ii. ()7. 

 (New Mexico and Arizona.) 



Var. asperulum: leaves thinner, ilidler, all nu)re lanceolate, their margins and 

 midrib nuu;h less strongly ciliate, the bristles soujetimes obscure and not retrorse : 

 peduncles and pedicels fewer ami not divaricate : corolla apparently purplish : fruit 

 not seen. — G. asperriiaam, Watson, liot. King. 134. 



In Mariposii Secpioia Grove (Bulandcr), .Sierra Valley {Lcmmo-it), and Ruby Valley, Nevada 

 ( Watson), if a variety of G. aspcrrimuiii, it nuist be a form growing in more shady places. 

 Leaves ^ to | of an inch long, those near the llowers smaller, almost awn-pointed. Corolla a lino 

 and a half in diameter. Perhaps the root is pereiuiial. 



* vc « Pere)ini(tls. 



+- With dijfiise or decumbent xvhoUy herbaceous sttum : fruit not lon(/-vilious : leaves 

 with more or less j^i'ovnnent luidrib, but no lateral nerves. 



6. G. triflorum, IMichx. Hlightly and sparsely hairy or nearly glabrous, bright 

 green : stems pro(;und)ent ov reclining, minutely spinulose backwards on the angles 

 (or rarely smooth) : leaves in sixes or sometimes in lives, thin, oblongdanceolate, 

 acute at both ends, or cuspidate-acundnate, the margins and often the midrib 

 beneath beset with very short commonly retrorse and hooked bristles : peduncles once 

 or twice .'{-forked ; tlio pedicels divergent : con)lla greenish : fruit hirsute with 

 slen<ler hooked bristles, or when mature merely roughened. 



Rather common in woods and thickets, from San Francisco northward and to the Sierra, ex- 

 tending through the northern parts of the continent. The foliage when drying exhales tlie 

 sweet scent of the European Aspcrula odoruta. Leaves one or two inches or less in length, 3 or 4 

 lines wide. 



7. Gr. trifidum, I^inn. Glabrous or nearly so : stems slender, ascending or 

 erect, dilfusely branched, mostly roughened on the angles: leaves 4-6 in the 

 whorl, commoidy 5 or 6 on the stem and 4 on the branches, varying from linciir to 

 oblanceolate, obtuse, the miilrib and margins more or less scabrous : peduncles soli- 

 tary or in tlirees, not longer than the leaves : llowers very small : lobes of the white 

 corolla and the stamens often only 3 : fnut smooth and nakt'(l. 



Wet and shady places, .same range as the [neceding. Stems 5 to LO inches high. Leaves 3 to 

 lines long. Corolhi barely a line broad. 



8. Gr. Bolandei'i, Gray. Apparently erect, diffusely and paniculately branched, 

 ■ minutely hirsute or nearly glabrous : leaves all in fours, thickish, oblongdin-
