2. EUCRYPTA, Nutt. Erect, with opposite bi- or tripinnately dis- 

 sected leaves, and axillary peduncled racemes of small whitish flowers. 

 Calyx 5-parted, not accrescent, not appendaged, campanulate. Corolla 

 small, campanulate, without internal appendages. Capsule globose, 

 8-seeded, each valve in dehiscence liberating 2 oblong- ovoid seeds, and 

 retaining between the placenta and the wall of the ovary 2 flattened and 

 lenticular or meniscoid ones. 



1. E. chrysaiitheinifolia (Nutt.), Greene. Stoutish, freely branching 

 though very erect, 13 ft. high, very leafy : racemes rather dense, little 

 surpassing the ample pubescent and slightly clammy tripinnatifid leaves: 

 calyx-lobes ovate, acutish: corolla white with a bluish tinge: free 

 rounded seeds corrugated; the concealed and flattened ones smooth. 

 Common in the hilly districts. April June. 



3. PHACELIA, Jussieu. Annuals, or a few perennials, with alternate 

 simple or compound leaves, and more or less scorpoid unilateral racemes 

 or spikes of blue or bluish flowers. Calyx mostly, or always, completely 

 divided into 5 sepals. Corolla deciduous; the tube commonly with 10 

 vertical folds or lamellae within. Capsule with narrow placenta and 

 1 oc corrugated or reticulate or pitted seeds. 



* Seeds 1 or 2 on each placenta; testa areolate or f arose. 

 J Perennials or biennials; leaves pinnatifid or entire. 



1. P. Californica, Cham. Stout sparingly leafy flowering stems 

 1 2 ft. high,/row a stout much branched depressed and very leafy woody 

 caudex: herbage canescent with a minute close pubescence, and setose- 

 hispid with scattered long white hairs : leaves mainly of a large elliptic- 

 lanceolate terminal lobe; the pinnae below few and reduced: racemes 

 erect, short and dense, in a short paniculate cluster at and near the 

 summit of the stem: sepals equal, lanceolate, 2 lines long in maturity, 

 erect, reticulate-veiny and with a strong midvein: capsule ovate-oblong, 

 acutish, 1^ lines long, 1-seeded: seed ovate-lanceolate, a line long, 

 deeply alveolate. Sandy hills and plains near the sea. Feb. Sept. 



2. P. imbricata, Greene. Stems erect, several from a stout perpen- 

 dicular perennial root, densely leafy at base only: panicle of geminate 

 racemes long and lax, the branches widely spreading: pubescence much 

 as in the last, but more scanty: corolla bluish : fruiting calyces compressed 

 and closely imbricated; sepals unequal, the broad deltoid-ovate outer one 

 larger than the others, these ovate-oblong, acutish, all hispid-ciliate, none 

 showing either distinct midvein or reticulation; seed 1 only. Dry hills 

 and valleys of the mountain districts back from the sea. June, July. 



3. P. nemoralis, Greene. Apparently only biennial, stout, erect, 

 rather widely branching, 24 ft. high; herbage light green, destitute of 

 pubescence but strongly hispid with stinging hairs: leaves simple, or with
