32 RUBIACEjE. Kelloggia. 



Gray, Proc. Am. Acad. vi. 539, & Bot. Calif, i. 282. — Single species : most allied 

 to Galopina of S. Africa. 



K. galioides, Torr. 1. c. Slender and glabrous or puberulent perennial, a span to a foot 

 high, with foliage of a Houstonia (leaves only opposite, lanceolate, sessile, with small and 

 entire or 2-dentate interposed stipules), fruit and paniculate inflorescence of a Galium, and 

 corolla (of Asperula) white or pinkish, 2 or 3 lines long, the lobes equalling or shorter than 

 the tube. — Mountain woods, mostly under coniferous trees, Sierra Nevada, California (first 

 coll. by Brewer and Torrey), south to mountains of Arizona, east to Utah, and north to Wash- 

 ington Terr, and N. W. Wyoming. 



21. MITRACARPUS, Zuccarini. (MtVpa, a girdle or head-band, evi- 

 dently taken in the sense of mitre, and nap-iras, fruit.) — Low annuals or per- 

 ennials (American and one or two African) ; with the habit of Spermacoce, and 

 with small white flowers. — Zucc. in Rcem. & Schult. Syst. Mant. iii. 210, name 

 given only in the accusative case, " Mitracarpum," in index rightly under the 

 nominative " Mitracarpus." Mistaken for a nominative, we have the ungram- 

 matical Mitracarpum, by Cham. & Schlecht., followed by A. Rich., DC, Endl., 

 Benth. & Hook., and wrongly corrected by Benth. Bot. Sulph. and Gray, PI. 

 Wright., into Mitracarpiurn. (Vide Proc. Am. Acad. xix. 77.) Staurospermum, 

 Thonning in Schum. PL Guin. 78, is of same date (1827). 



M. foreviflorus, Gray. Annual, a span or two high, nearly glabrous and smooth, bearing 

 2 or 3 axillary verticillastrate-capitate clusters and a terminal one : leaves lanceolate, about 

 inch long : stipules with few setiform appendages : two larger calyx-lobes lanceolate-subu- 

 late, longer than tube, equalling or surpassing the small (barely line long) glabrous white 

 corolla ; intermediate ones small and dentiform, hyaline. — PL Wright, ii. 68 ; Kothr. in 

 Wheeler Eep. vi. 137. — Ravines and hillsides, S. Arizona, Wright, Thurber, Rothrock, &c. 

 (Adj. Mex., Berlandier, &c.) 

 M. linearis, Benth. Bot. Sulph., of Lower California, 'also coll. by Xantus, has narrow leaves, 



and tube of corolla at least twice the length of the calyx. 



22. RICHARDIA, Houst., L. (Dr. H. Richardson of London, father of 

 Richard Richardson, the correspondent of Gronovius, &c. See Smith's Corr. 

 Linnaeus and other Naturalists, ii. 173.) — Hispid or hirsute perennials or annu- 

 als, natives of Tropical America; with broadish subsessile leaves, setiferous 

 stipules, and whitish flowers ; these mostly in a terminal capitate cluster, involu- 

 crate by the one or two uppermost pairs of leaves. — Gen. PL ed. 1, 100; Gasrtn. 

 Fruct. t. 25 ; Ruiz & Pav. Fl. Per. & Chil. t. 279 ; Hiern in Fl. Trop. Afr. iii. 

 242. Richardsonia, Kunth in Mem. Mus. Par. iv. 430, & HBK. Nov. Gen. & 

 Spec. iii. 350, t. 279 : but it appears that this, which correctly indicates the 

 naturalist to whom the genus was dedicated, cannot be allowed to supersede the 

 original name, faulty as it is in this respect. 



R. scabea, L. Loosely branching. and spreading: leaves ovate to lanceolate-oblong (inch or 

 two in length), roughish : stipules with rather few setiform appendages: glomerules of 

 flowers and fruit depressed : corolla 2 or 3 lines long. — Spec. i. 330. R. pilosa, Ruiz & Pav. 

 1. c. ; HBK. 1. c. Richardsonia scabra, St. Hil. PI. Us. Bras. 8, t. 8 ; DC. Prodr. iv. 567 • 

 Chapm. PL ed. 2, Suppl. 624. — Low or sandy grounds, abundantly naturalized in the low 

 country, S. Carolina to Texas, called Mexican Clover in Alabama, and relished bv cattle ■ the 

 root in S. America used as an emetic and as a substitute for Ipecac. Sparingly" occurs as a 

 ballast-weed at Northern ports. (Nat. from Mex. & S. Am.) 



23. CRtTSEA, Cham. (Prof. Wm. Cruse, of Kcenigsberg, who wrote on 

 Rubiaceee.) — Perennials or annuals (of Mexico and adjacent districts), with habit
