In this obscure genus we have hardly any 

 characters that can be depended upon. Those 

 founded on the form of the Corolla, whether 

 short, campanulate, and beUying in front, fun- 

 nel-shaped, or with a nearly cylindrical tube, 

 are good as far as they go. In the second 

 division the tube is contracted above the ger- 

 men, or rather the swelling of the germen 

 dilates the lower part of the tube, — a circum- 

 stance which only takes place in two or three 

 species of the first division. The natm-e of 

 the cm-ve on the back of the tubular flowers is 

 perhaps sometimes of value ; but a considera- 

 ble difference in this respect takes place in the 

 flowers of the same spike, and it is affected by 

 the gi'owth of the fruit. A little curve backwards 

 at the tip of the upper lip occm's in most if not 

 in all the species. The divisions and proportion 

 of the lower lip deserve, perhaps, more atten- 

 tion than they have hitherto received. They are 

 always rounded and plaited, very rarely with 

 an acumen, and more or less separated by a 

 plaited, or sometimes inflated, interval. The 

 middle lobe in some species is said to be twice 

 as large, or twice as long, as the lateral. This 

 I have not been able to verify. In one or two 

 species of the first division the coroUa is said 

 to be quite hairless, but in the rest it is gene- 

 rally more or less covered with glandular hairs ; 

 and these, in a few instances, extend to the 

 inside of the upper Up. The Filaments in 

 some are densely, and, I believe, constantly 

 villous at the base ; in others they are quite 

 smooth ; but in the majority of instances they 

 vary from quite smooth to hairy mth scattered 

 hairs. The Glands on the top of the fila- 

 ments and the style seem to be stiU more 



uncertain. The Anthers are in general ovoid, 

 prolonged, acute, mucronate ; but in 0. minor, 

 and perhaps some other species, they are almost 

 round, and with a hardly distinguishable point. 

 The Stigma, more or less completely divided 

 into two lobes, may perhaps be of use ; but the 

 colom% which has been much insisted upon, 

 cei'tainly varies in some species, and is sus- 

 picious in aU. Reuter, in the ' Prodromus,' 

 forms two sections dependent upon the posi- 

 tion of the Stamens, near the base, or near 

 the middle of the tube of the coroUa. In his 

 desci'iptions of his first section we have the 

 terms " on the base," " at the base," " near 

 the base," and " above the base." The latter 

 expression is, however, also used in the next 

 section, as in 0. Salvia^, 0. laurina, 0. gla- 

 berrima, and 0. macrosepala. In 0. littorea 

 and 0. loricata they are described, from Ber- 

 toloni, as a Uttle above the base ; in 0. fra- 

 grantissima, somewhat distant from base; in 

 0. serotina, toward the base. Bertoloni often 

 measures the distance ; but 0. Crithmi, 0. 

 canescens, and 0. australis, where the distance 

 from the base of the coroUa is only one line, 

 are placed by Reuter among those whose 

 stamens are inserted near the middle of the 

 tube, as well as those where they are 2 Unes or 

 2-i lines from "the base. 



The next point is the Calyx. According to 

 Godron, ' Fl. de Lorr.' the Sepals in Div. A 

 are touching or united in 0. major, 0. elatior, 

 0. caryo'phyllacea, 0. Teucrii, and 0. nibeiis ; 

 quite separate in O.Cervarice {ox brachi/petala), 

 0. Picridis, and 0. Hpithymum. They are 

 almost always ovate at the base. In some 

 species they are described as entii'e, in others 

 as constantly dividing into 2 or 3 segments. 

 So many, however, vary in this respect, that we
