like that of edulis. Erythea Brandegei is at once separable from all 

 others (^except amiata) by the pipe-stem' jjetioles' and ^^alMeaves. The 

 jpetioles of all the other species of th two genera are 2-4 inches w^de, 

 while those of Brandegi are about half an inch to two inches wide. 

 \Vhether E. elegans Frahchesi and E. aculeata Brandegee are good' spe- 

 cies I am not prepared to say. But I know all the species of Wash- 

 ingtonia as heretofore recognized, and am satisfied that they are gen- 

 erically distinct from Erythea (Glaucothea). 



The fruit of Erythea elegans Franchesi is acuminate below. The 

 fruit of all the rest is globose. The fruits' of armata and Brandegei are 

 about half an inch long. Those of edulis and aculeata are an inch long 

 Leaves of edulis are not spinose, those of aculeata are spincse. 



The flowers of Erythea armata are greenish-white. Calyx about 1 

 mm. long with the nearly round Icbes very concave and lacerate on th^ 

 margins and separate middle. Just below the tips of the calyx the 

 white corolla lobes flare about 45 degrees and are deltoid-ovate and 2 mm. 

 long and acute, the lobes s^em united near the base within calyx and corolla 

 is a cup formed by the united filaments which are scale-like and united 

 half way up or almost to the tip and adnate below to the corolla. The 

 elliptical anthers are nearly 3^ mm. long and versatile and on a minute 

 but evident pedicel. The ovary is 3-lobed and with stigmas ahout sessile. 



The flowers of armata are in long and greenish panicles, the per- 

 ianth at length white and 2 mm. long and parts triangular-ovate. Th^ 

 6 stemens form a cup around the ovary, v/ith the greatly expanded fila- 

 ments flat and deltoid and with the oval anthers about 1-10 mm. long 

 .fitting on the tip. The cup is cither complete by the vr^on of the 

 filaments almost to the tip, or by the parts being slightly imit^^d at base. 

 The flowers are strongly odorous, smelling resinous, the flovrer'; appear 

 cup-like and rather open. At Claremont tliere seem to be two flower- 

 in -^ seasons, one in May and the other in Au.CTist, The fru'it oT edulis 

 when ripe is black and juicy and smooth and fully an inch in diameter, 

 i?Iobo"e or nearly so, or a little oblate, when hrs ripe is reddish -yellow 

 The fruit never seems to be but 1-seeded, Infioorescence minutely liairv'. 



A character not clearly noted that separates the Erv^th'^as f-om 'Wash- 

 ingtonia lies in the bracts of tlie inflorescence, Jn TErythea fliere Is a 

 relatively short bract at the base of each grape-like cluster vhich tightly 

 hui^s the rachis and is not prolonged into a leaf, and there f'^re i- Incon- 

 sricuous. The inflorescence of E. edulis is a uniform panicle o-4 feet 

 long, ovate to lanceolate in outline and on a short peduncle much .shorter 

 than the petioles. The general appearance of the panicle is that it is 

 concealed among the leaves. The panicle of E. armata is a "long raceme 

 of grape-like clusters, and each cluster separate and rather distant from 

 the next one. The main peduncle 'is nearly as lonr^ as the petioles, and 

 so the panicle is exserted. The panicle of Brandegei ir> that of e^^ulis. 



In Washingtonia the inflo-escence 'is about the same as 'in E. armata^ 

 but each cluster has the subtending bract elongated and as lor,^ or longer 

 than the cluster. A foot or two long, and white and about "2 'iiicfes Tvlde 

 nd like a corn leaf, and is alv.-ays Tery conspicuous.
