sterile branclilets commonly all opposite: corolla ochroleu- 

 cous inside, bronze-purple without, lobes a half inch long, 

 oblanceolate, the broad apex abruptly pointed: anthers lin- 

 ear-oblong, a little exserted from the throat: ovules 4 — 6 in 

 each cell. 



Cedros Island, common on stony hills, forming compact 

 rounded masses a foot or two in breadth and height. First 

 collected in fruit by Dr. Veatch in 1859; obtained in 

 flower by the writer, April 30, 1885. The species is more 

 like the northern G. punjeus, than G. Cali/ornica, but is 

 very distinct from both. 



EUCRYPTA, Nuttall, PI. Gamb. in Journ. Acad. Philad. Ser. 2, i. 158. 



Calyx 5-parted, the sinuses naked. Corolla small, tubu- 

 lar-campanulate, without appendages. Capsule globose, 

 8-seeded, 2-valved, each valve in dehiscence liberating 2 

 oblong seeds, and long retaining concealed in a false cell 

 formed by its wall and the placenta, as many meniscoidal 

 ones. Seeds corrugated or smooth; testa not reticulate. 

 Erect, paniculately branching, viscid Pacific-coast annuals, 

 with small racemose flowers. Ellisia § Eucrypta, Gray,

These plants are not at agreement with Ellisia in habit. 

 Put if they were, capsules of such remarkable structure, 

 and with seeds of two sorts so strikingly dissimilar, neither 

 sort answering to those of Ellisia or of any other Hydro- 

 phyllaceous genus, must, it seems to the writer, establish 

 strongly enough a genus which was long ago well defined 

 by an eminent authority. The name (meaning " well hid- 

 den") is very admirably appropriate; for the pair of flattened 

 seeds (rarely by the abortion of one ovule, solitary) which 

 lie between the wall of the valve and its placenta, are so 

 closely sealed as to have escaped the detection of that great 

 botanist, the late Mr. Bentham, into whose hands one or 

 both of the species fell at an earlier date than that of Mr. 

 Nuttall's treatment of them, and who therefore described
