Boraginaceae. Dicotyledons (Sympet. Tubiflorae). About 85 gen. 
with 1200 sp., trop. and temp., esp. Medit. Most are herbs, perennial 
by fleshy roots, rhizomes, &c. ; a few shrubs and trees. Leaves 
usually alt., exstip., generally, as well as the rest of the plant, covered 
with stout hairs (hence the name Asperifolieae, by which the B. are 
sometimes known). The infl. is a coiled cincinnus, sometimes double, 
with a marked dorsiventrality. As the firs, open it uncoils, so that the 
newly opened firs, face always in the same direction. The morphology 
of this infl. is but imperfectly understood ; adnation or concrescence 
occurs (p. 30), and apparently dichotomy at the growing apex. The 
general agreement is, however, in favour of the view that the 
“boragoid,” as it is sometimes called, is composed of dorsi-ventral 
monopodia. Cf. Nat. Pfl. y Muller in Flora , 94, Schumann, Morphol .

Fir. g » usually regular, hypogynous, and 5-merous. K (5), imbri- 
cate or open, rarely valvate, the odd sepal 
posterior; C (5), funnel-shaped or tubular, 
the limb usually flat ; A 5, epipetalous, 
alternate to petals, anthers introrse ; G (2), 
on hypogynous disc, usually 4-locular by 
‘false* septum (see Labiatae), usually with 
gynobasic style ; ovules 1 in each loc., 
erect, anatropous. Fruit a drupe or 4 
achenes. Seed with straight or curved 
embryo in usually slight endosperm ; the 
radicle directed upwards. 
The floral arrangements are interesting. 
Most B. have a short tube, partly conceal- 
ing the honey; many (esp. iv. 1 and 3) have 
scales projecting inwards from the throat 
of the corolla, thus fully concealing the 
honey, protecting it from robbery and narrowing the entrance, so 
that visiting insects must take a definite track. “The lower forms 
( e.g . Myosotis) are visited by flies (esp. Syrphidae), bees, and Le- 
pidoptera, and are adorned with red, violet and blue colours
