et restant enfoncées dans la fleur, ce qui le place parmi les Phytarrhiza 
et le T. Dasyliriifolia Bak. appartient aussi à la section Platystachys; il 
a des fleurs violettes, croît dans l'Amérique centrale et au Mexique et a 
aussi des affinités avec notre espèce, mais s'en distingue parce qu'il est 
acaule et que les bractées sont plus courtes que les sépales, alors que, 
chez le T, Langlassei, le calice est complètement recouvert par les 
bractées. — Mexico: E. Langlassé no. 1013 bis Providencia, altitude 
900 m; récolté le 29 juin 1899.

— Perennial hirsute or hispid plants, branching considerably: leaves 
rather thick whorled, one-nerved, mucronate: flowers white, few, at the 
ends of small branches: pedicels stout reflexed in fruit which is a black 
berry, glabrous or minutely pubescent: ovules one in each half of the 
berry. Otherwise as in Galium. Plants of the Southeastern coast region 
of the United States.

p. 204. — Planta annua, obscure viridis, ex superiore radice 2—4 ramos 
crassos et tot graciles, sicut flabellum irradiantes, emittens; rami ipsi 
pluries furcati et profuse crescentes, humi prostrati, saepe 3 dm diametro. 
Caulis teres, vivide et obscure ruber. Herba tota glabra est. Folia 
distincte petiolata, opposita, 5—17 mm longa, spatulata vel oblonga vel 
obovata, ad basim angustata, obliqua, saepe falcata, crenulate-serrulata 
de superiore parte marginis magis curvatae usque per totam marginem 
minus curvatam, vel non raro per totam circumferentiam haud indentata. 
Apex obtusus, rotundatus (numquam truncatus vel retusus). Folia saepe 
zonam rubram latam in medio habent et marginibus vivide colorata sunt. 
Involucrum triangulatis lobis et subulatis. Semina fusca, quadrangulata, 
angulis eminentibus, inter angulos conspicue rugosa, et inter rugas de- 
pressa. — North Dakota: The plant grows where the ground is level, 
and develops its fullest beauty where no intruding plants share with it 
the space needed for its entire expansion. — A species that may be apt 
to be confounded with this is C. rugulosa (Engelm.) Rydb., with its 
thickly matted growth and leaves toothed along the whole of the less 
curved side, but its seeds are turgid and very finely rugulose, with deep 
and irregular pits, and the apex of the leaf is retuse (vide Pittonia II, 
plate 1). C. serpyllifolia (Pers.) Small, differs in having oval, retuse 
leaves, crenulate at the apex, is procumbent (Persoon, Synopsis Pla- 
tarum, Vol. II, p. 14 [1807], and has an angled, in the type almost 
winged stem (vide, Pittonia, l. c.). C. neo-mexicana (Greene) is erect, 
with branches acutely angled, with elongated, sharply pointed seeds, 
the two ventral facets being concave, and the lobes of the involucre 
entire or 2—3-cleft. C. consanguinea (Engelm.) is rather erect, the apices
