 sphagrica, testa laxa favosa. — B. Hooheri is probably of this section 

 in all its charactei'S. B. slrobilacea is perhaps only the well-grown 

 form of it. An examination of the original at Kew should deter- 

 mine this. 



Addendum to Papaveracece. 



Papaver Californicum. p. dubio perquam simile, pilis parcis 

 forte tenuioribus ; corolla crocea oculo citrina ; capsula (circiter semi- 

 pollicari) clavato-turbinata 6-11-mera, valvulis dentiformibus siibquad- 

 ratis lineam longis latisque placentas nudantibus dehiscente; seminibus 

 rete grossa parca fenestrali. — Santa Inez Mountains, California, coll.

One is naturally slow to believe in an indigenous Californian Corn 

 Poppy. In the spring of 1886 that excellent florist and acute ob- 

 server, Mr. Spence, of Santa Barbara, sent me some flowers of this 

 plant which he had hastily picked up in the Santa Inez Mountains, at 

 the elevation of 1,500 or 2,000 feet, far away from any cultivation, on 

 ground which had been covered with Manzanita, but had been burned 

 over the year before. These flowers and forming pods, so far as could 

 be told by inspection, might have belonged to Papaver dabiutn or 

 P. Rhceas, species which might be expected to abound in old Califor- 

 nian wheat-fields, although they had not there been met with to my 

 knowledge. At this moment I receive from Mr. Spence a supply of 

 mature capsules and seeds gathered last summer at the same station, 

 or partly at another similar station, about forty miles farther west, 

 " far away from any trail," on ground which had similarly been burned 

 over ; and with these some flowering materials raised from their seed 

 in his conservatory. These capsules are so like those of P. dubium 

 that, apart from their history, they might pass for such. But they all 

 (nearly one hundred in number) have the peculiarity described in the 

 character. They dehisce — just as do those of their compatriot and 

 almost congener Meconopsis heterophylla — by decided valves, of a line 

 in length, exposing the septa for that length, recurving, and at length 

 breaking off square at their base. Moreover, the seeds — which are
