Cahjptrocarpus of Lessing, which is characterized as having "achae- 

 niuni plano-obcompressuin .... intcrruptc et aoguste alatum." A 

 tuberculate winged margin of this sort is mauifest in some of the 

 outer akeues of Texan and Mexican specimens. »S'. peduncularis of 

 Beutham appears to be the connecting link between this species and 

 S. nodljiora. The autlior would doubtless have added this third 

 species, if he had noticed that the akenes of the disk as well as the 

 ray are obcompressed and dorsally subtended by narrow flat chaff. 

 And so De Candolle's Oligogyne is described. Blainvillea is quite 

 different in these respects. But to Blainvillea, and certainly not to 

 this species, belongs B. biristata,T)C. (the Galophthalmum Brasiiiense 

 of Nees and Martins), of Brazil.

 tis fimbriato-laciniatis aristis subulatis dimidio brevioribus. Bahiopsis 

 lanata, Kellogg, Proc. Calif. Acad. ii. 35. — Cerros Island, Lower 

 California, Veatch, Street, Belding. — Through the kind attention of 

 Dr. Parry, we possess an original specimen of Dr. Kellogg's Bahiopsis, 

 which is here characterized. It is quite different from the plant 

 doubtfully named Viguiera nivea, Benth. ? in the Botany of Califor- 

 nia, which, falling back to its earliest specific name, now becomes V. 

 tephrodes. Nor is it the Encelia nivea, of Benth. Bot. Sulph. 27, 

 which is still ambiguous. The original at Ivew appeared to me desti- 

 tute of pappus, and Bentham's note, in Gen. PI. ii. 376, leaves it to 

 be inferred that he saw none. There is a jjlant collected in Lower 

 California by Lieutenant Belding which accords with Bentham's 

 description, except that the leaves are alternate, and there is a very 

 caducous pappus of two aristiform paleiv, but no intermediate squamella^. 

 The akenes, when known, will j^robably refer it to Encelia rather than 

 to Heliantlms. But it is to be noted that Encelia nivea, Benth., is 

 said to come from San Quentin. Now the only San Quentiu we 

 know is on the Bay of San Francisco. But the plant at Kew was 

 not recognized on inspection.
