Boraginaceae (EP., BH.). Dicots. (Sympet. Tubiflorae; Polemo- 

 niales BH.}. 85 gen. 1600 sp., trop. and temp., esp. Medit. Most 

 are herbs, perenn. by fleshy roots, rhiz., &c. ; a few shrubs and trees. 

 L. usu. 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). Infl. a coiled cincinnus, sometimes 

 double, with a marked dorsiventrality. As the fls. open it uncoils, 

 so that the newly opened fls. face always in the same direction. The 

 morphology of this infl. is but imperfectly understood; adnation or 

 concrescence occurs, 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., Miiller in Flora, 94, Schumann, Morphol.

 with gynobasic style ; ovules i in each loc., 

 erect, anatr. Fr. a drupe or 4 achenes. 

 Seed with straight or curved embryo in 

 usually slight endosp. ; the radicle directed 

 upwards. [Cf. V.] 



The floral arrangements are interesting. 

 Most B. have a short tube, partly conceal- 

 ing the honey; many (esp. IV. i and 3) have 

 scales projecting inwards from the throat 

 of the corolla, fully concealing the honey, 

 protecting it from robbery and narrowing 



the entrance, so that visiting insects must take a definite track.
