HYDROPHYLLACEiE. 419 



spatulate sepals, the limb minute: capsule oval, erect : seeds globular, obsoletely rugulose, 

 and with a very smooth thin coat. — Gray, 1. c. — With the foregoing, Lemmon. 



N. dichotomum, Chois., uot Ruiz & Pav., who liave it as Hjjdrolea dichutoma. The re- 

 markable var. aiKjusli/olium extends well iuto Mexico. — Next to this species is 



N. origanifolium, HBK. rerennial, herbaceous from a lignescent base, or suffruticulose, 

 low and small : leaves oblong or spatulate-obovate, sessile by a narrowed base or short- 

 petioled, soft-pubescent, a (juarter to half inch long, the margins somewhat revolute : flowers 

 short-peduncled : corolla 3 lines long, surpassing the calyx : sepals linear, moderately dilated 

 upward, nearly twice the length of the ovoid capsule : seeds about 20, oblong, smooth. — 

 Nov. Gen. & Spec. iii. 130, t. 218; Gray in Hemsl. 1. c. 3G2. — Crevices of rocks, Guadalupe 

 Mountains, S. W. Texas, near the Kio Grande, Ilacard. (Mex.) 



N. Lobbii, Gray, p. 175. — Gray in Hemsl. Biol. Centr.-Am. Bot. ii. 3G2. Eriodictyon 

 Lobbii, Greene, Bull. Calif. Acad. i. 202. Ovules about 8, pendiilons. Capsule obovate- 

 globose, thin-coriaceous; valves tardily bifid, the narrow placentte breaking up. Seeds 

 broadly oval or roundish, half a line long, large for the capsule, with a smooth minutely 

 cellular-reticulate coat. 



N. Havardi, Gr.vy. Near N. Palmeri and the next, a foot or more high, herbaceous from 

 a lignescent probably perennial root, more or less cinereous with soft jtubescence : stem erect 

 and stout, freely branching : leaves oblong or uppermost lanceolate, acutish, with tapering 

 base, lower somewhat petioled, veins very obscure : flowers cymulose, short-pedicelled : 

 corolla 4 or 5 lines long, salverform, apparently purplish, a little longer than the calyx : 

 filaments adnate to the middle and below membranaceous margined, tootliless : capsule 

 oblong-ovoid, membranaceous, much shorter than the narrow-linear slightly dilated sepals : 

 seeds 16 or more, globular or short-oval, with a firm faintly scrobiculate coat. — Proc. Am. 

 Acad. XX. 304. — S. W. borders of Texas, on alkaline bank of Tornillo Creek, Havard. 



N. stenophyllum, Gray. Suffruticose, a foot or less high, rather stout, strigulose- 

 cinereous or more loosely hirsute : stems very leafy throughout : leaves from narrowly linear 

 to almost filiform, about an inch long : flowers densely cymulose at the summit of the 

 branches: corolla nearly salverform (4 or 5 lines long), more or less suriiassing the calyx: 

 margin of the filaments on each side terminating above in a free short denticulation : cap- 

 sule ovoid-oblong, thinnish, much shorter than the narrow linear obtuse sepals: seeds about 

 40. globular and angulate, a third of a line long, muricate ! — Biol. Centr-Am. 1. c. (e.xclud- 

 ing the hist line of the character, the jtrintcr's error: it belongs to N. stenocarpum), & 

 Proc. Am. Acad, xviii. 118. — S. W. border of Texas, on bluffs of Delaware Creek, east of 

 Guadalupe Mountains, 1882, Havard. (Adj. Mex., Palmer.) 



N. Rothrockii, Gray, p. 175. Valves of the ovate capsule not splitting in age. 



N. Parryi, Gray, p. 175. Valves of the short oval capsule splitting into two after dehis- 

 cence, the placentie breaking up : stem 3 to 6 feet high, at base " pithy and only soft-woody " ; 

 perennial : " tube and throat of corolla white, lobes light purple," Parish. Collected also in 

 the Sierra Madre of Los Angeles Co by son of J. C. Nevin, 1884. 



13. ERIODlCTYON, Benth. P. 175, 17G, add: — 



E. sessilifolium, Grkkne. Very leafy : pubescence partly villous and hirsute: leaves ob- 

 long or upjicr (jiies lanceolate, all closely sessile by a broad and truncate or subcordate base, 

 acutely and closely dentate (in age becoming glabrate and glutinous above) : otherwise 

 nearly like the E. crassifoliuin form of E. tomcntoanm. — Bull. Calif. Acad. i. 201 . — Guada- 

 lupe Canon, and elsewhere in Lower California, not far below the U. S. boundary to All 

 Saints' Bay, Parrij, Orcutt, and recently Greene. The seeds (with delicate striaj and trans- 

 verse reticulation) appear to be (juite alike, as far as seen, in all the species and forms, which 

 are ver}' difficult to define. 



E. tomentosum, Bknth., p. 176, is founded on a plant with ])annose tomentum and no 

 villous or hirsute pubescence until the inflore.scence is reached, snch as Greene in Bull. 

 Calif. Acad. 1. c, (lcscrib«s from Monterey Co., but with the corollas seemingly in the same 

 imperfectly developed or deformed condition which Bentham had in his E. crassifoliuin, in
