420 SUPPLEMENT. 



this state "hardly surpassing the calyx (2 lines long)," and its lobes "very small, erect- 

 spreadiug." But well-developed flowers of E, crassifolium we know to be even half an inch 

 long and much surpassing the calyx. On Santa Catalina, Li/on got a narrower-leaved 

 form of the true E. tomentosum, with finer tomeutum not pauuose on the stem, and normally 

 developed salverform corollas. 



A multitude of forms from Lower and Southern California (including E. angustifolium, 

 var. pubens, Gray, Proc. Am. Acad. xvii. 224), with and without villous or hirsute inflores- 

 cence, now connect E. angustifolium with E. glutinosum. This extends northward to Oregon, 

 coll. Howell. 



BORRAGINACE^E. 



The following changes in the synopsis of the genera are, for brevity and con- 

 venience, based on the North American representatives. 



H- (P. 178, line 36.) Nutlets attached above the middle, wholly flat and thin, horizontally 

 divergent, in pairs or radiate; margins pectinately and uncinately setiferous. 



8. PECTOCARYA. 



-H. -H. Nutlets thicker, with ventral or introrse-basal attachment. 

 = Glochicliate-armed: corolla short, with fornicate throat: calyx spreading or reflexed in fruit. 



9. CYNOGLOSSUM. Nutlets horizontally radiate or barely ascending, much produced 

 below the high ventral insertion upon the low gynobase, on separation each pendulous by a 

 portion of the style which is torn away from below upward. 



10. ECHINOSPERMUM. Nutlets erect or much ascending; the insertion supra-basal, 

 central, or from the inside of base to apex. 



= = Not glochidiate, nor with loose or fleshy pericarp. 



a. Corolla short, white or blue (only in an anomalous species elongated and yellow), usually with 

 more or less fornicate throat. 



11. OMPHALODES. Nutlets obliquely ascending (or in typical species depressed^ and 

 nearly horizontal), with depressed or truncate-complanate back bordered by an acute mar- 

 gin or an at length revolute (entire or dentate or spiuulose) wing: scar short, from supra- 

 basal to supra-median. 



1 1 1 . KRYNITZKIA. Nutlets erect and straight, with wing or border, if any, unarmed and 

 plane, with iutrorse-basal or also ventral attachment from the base upward, the scar or 

 groove of attachment wholly naked. Fructiferous calyx erect or little spreading. (Includes 

 also no. 14, p. 179.) 



12. PLAGIOBOTHRYS. Nutlets crustaceous or rarely coriaceous, ovate or trigonous, 

 oblique or incurved, and often incumbent over the low gyuohase, to the depressed areola of 

 which they are attached by a median and either perforated or solid (sessile or short stipi- 

 tate) false caruncle. 



13. ECHIDIOCARYA. Nutlets ovate-pyramidal, with ventral keel produced at base into 

 a conspicuous indurated stipe ; the stipes united in pairs below and inserted by a common 

 excavated base to the low gynobase. Otherwise as Plagiobothrys. 



b. Corolla yellow, with usually more elongated tube and naked open throat. 

 14- AMSINCKIA. As on p. 179. 



= = = Not glochidiate nor appendaged, with loose pericarp soft and thin or fleshy: corolla 

 from campanulate to trumpet-shaped, with open throat. 



15. MERTENSIA. As on p. 179. 



H- -H- -H- (in place of = =, p. 179.) Nutlets erect, with direct and centrally basal attachment 

 to the depressed gynobase. (16- 21.) 



ASPERUGO FROctfMBENS, L., a European annual, well marked by its much enlarged mem- 

 branaceons and veiny fructiferous calyx, has sparingly appeared in waste grounds around New 

 York and Philadelphia, and at the red pipestone quarry in Minnesota. 



C6RDIA GREGGII, Torr., p. 180, remarkable for its large flowers and small leaves, has been 

 found by Pringle not far below the boundary in Sonora, near the Gulf of California.
