Krameria Loefl. Leguminosae (11. 6). 13 sp. Mexico to Chili. It is 
placed in Polygalaceae by Benth.- Hooker, but has a petal, not a 
sepal, posterior. K and C 4 — 5 ; A 4, anthers opening by pores. 
See Eichler, Bluthendiag. p. 522. 
Kraunhia Rafin. = Wistaria Nutt. 
Krokeria Moench = Lotus Linn. 
Krynitzkya Fisch. et Mey. Boraginaceae (iv. 2). 40 sp. W. Am. 
Kuhnistera Lam. = Petalostemon Michx. 
Kyllinga Rottb. Cyperaceae (11). 40 sp. trop. 
Labiatae. Dicotyledons (Sympet. Tubiflorae). About 150 gen. with 
2800 sp., cosmop. The chief centre is the Medit. region. Some of 
the small sub- orders are localised in their distribution, e.g. II. in 
Austr. and Tasmania, III. in India, Malaya, China, & c., VIII. in 
Centr. Am., whereas the large ones, such as I. and IV., are cosmop. 
Most L. are land-plants, and herbs or undershrubs, exhibiting much 
similarity in habit and structure. Stem usually square, with decus- 
sate simple exstip. leaves, often hairy and with epidermal glands 
secreting volatile oils, which give characteristic scents to many plants 
of the order. There are a few marsh-plants (Mentha, Lycopus, &c.), 
a few climbers (sp. of Stenogyne, Scutellaria, &c.), and a few small 
trees (Hyptis sp.). Many are xerophytes with reduced, sometimes 
infolded, leaves, hairiness, thick cuticles, &c., e.g . Rosmarinus. 
The axis of the first order is not closed by a fir. but only those of 
later orders ; thus the primary form of the infl. is racemose, and a 
simple raceme actually occurs in Scutellaria, &c. Usually however a 
dichasial cyme, becoming cincinnal in its later branchings (p. 64), 
occurs in the axil of each leaf upon the upper part of the main axis. 
In Teucrium, Nepeta sp., &c., the 
construction of this cyme is easily seen ; 
but in most L. it is closely ‘ condensed * 
into the axil, so that all the firs, are 
sessile ; even here, however, it is easily 
seen that the central fir. opens first and 
then those on either side of it (see 
diagram). The two condensed cymes 
at each node overlap the leaf-axils and 
often form what looks like a whorl of 
firs.; this infl. is often called a verticil - 
taster or false whorl. 
Fir. g or gynodioecious, zygomor- 
phic, hypogynous, 5-merous with sup- 
pression in some whorls. The common formula is K (5), C (5), A 4, 
G (2). Calyx hypogynous, tubular, bell- or funnel-shaped, some- 
times 2 -lipped, persistent in fruit. Corolla usually 2 -lipped with no 
clear indication of the individual petals. Sta. 4, didynamous, or of 
nearly equal length, sometimes 2, epipetalous with introrse anthers.
