most wortlij'. whose botanical collections in Mexico have been un- 

 excelled in character and who has added very greatly to our knowl- 

 edge of the Mexican flora.* The genus has hitherto been placed 

 jirovisionaliy in the Cclastracece. Its affinities are rather with Alva- 

 rudoa in the Saplndacece. 



Neotringlea integrikolia. {Llavea inter/rifolia, Ilemsl ) Com- 

 plete specimens of this hitherto imperfectly known dioecious shrub 

 have been collected by Mr. Priugle on San Jose Pass, San Luis Po- 

 tosi ; in flower, July (n. 3137), and in fruit, October (n. 3248). The 

 staminate flowers are in short crowded axillary racemes, tetramerous, 

 the four greenish petals orbicular, pubescent, not exceeding the sepals : 

 stamens 12, in threes opposite to the petals, in the sinuses and inter- 

 vals between the pubescent lobes of the disk ; pistillate flowers with- 

 out petals or disk, the 3-winged ovary 3-celled at base, with solitary 

 anatropous ovules on the axis : capsule 1-celled, 1-seeded ; seed com- 

 pressed-obovate, the embryo straight in rather thin albumen, with flat 

 cotyledons and rather slender inferior radicle. 



Desmodium subspicatum. Stems erect from a narrow fusiform 

 root, somewhat woody at base, glabrous or slightly puberulent, 18 

 inches high : leaves nearly sessile, the single leaflet linear-lanceolate, ob- 

 tusish at base, acuminate and ver}^ acute, 1 to 3|- inches long, glabrous 

 or nearly so : racemes pubescent, terminal, simple and spike-like, 

 the small greenish flowers solitary or in pairs, on jjedicels a line long 

 or less, the lanceolate bract about equalling the calyx : legumes erect, 

 pubescent, 9 lines long or less, 3-5-joiuted, nearly equally indented 

 on both sutures and the joints elliptical. — On grassy hillsides at Las 

 Canoas, San Luis Potosi ; July. 1890 (n. 3211). Kear D. amjustifo- 

 liiim, DC, as that species is described. 



Desmodium amaxs. Tall, erect, the stem, petioles and inflores- 

 cence clothed with shoi-t hooked hairs : stipules attenuate from a 

 broad base, villous ; petioles about \ inch long ; leaflets rather thick 

 and reticulately veined, narrowly oblong, acute, rounded at base, gla- 

 brous above, villous beneath, 14^ to 2 inches long by 6 lines broad ; 

 stipels subulate, attenuate: racemes in a naked terminal panicle; 

 bracts ovate, acuminate, 3 lines long ; pedicels becoming 3 or 4 lines 

 long : calyx-teeth exceeding the tube, unequal, the lower longer and 

 narrower ; petals purple, 3 lines long : legume 5-7-jointed, with the 

 two sutures nearly equally sinuate, the suborbicular joints \-\ lines

 Berginia, Harvey, as was first suggested by Mr. Brandegee.
