Nov., 1912. DIAGNOSES OF SPERMATOPHYTES GREENMAN 339 



Ehretia tehuacana Greenman, sp. nov. 



Arbor (?); ramis teretibus glabris; ramulis juventate glanduloso- 

 puberulentis et interdum sparsissime hirsutis setate glabris; foliis 

 petiolatis ovato-oblongis 4-8.5 cm. longis 2-5 cm. latis acutis vel 

 rotundatis apicem versus dentatis infra mediam integerrimis basi 

 plus minusve inaequalibus obtusis vel subrotundatis supra hispido- 

 scabris atroviridibus subtus pallidioribus cano-hirsutisque; petiolis 0.5- 

 1.5 cm. longis pubescentibus ; calyce campanulato 2.5-3 mm - longo 

 5-lobato subglabro, lobis ovatis acutis ciliatis; corolla alba (?) infundi- 

 buliformi circiter 10 mm. longa glabra, limbo 5-lobatis, lobis ovato- 

 rotundatis 2.5 mm. longis 2 mm. latis patentibus; staminibus exsertis; 

 drupa ovoidea 6-8 mm. longa glabra; seminibus subcylindratis circiter 

 4 mm. longis. MEXICO. State of Puebla: las Mohoneras, Tehuacan, 

 altitude 2200 m., 22 June, 1908, C. Conzatti, no. 2220 (hb. Field Muse- 

 um, cat. no. 235156, type), flowering specimen; San Nicolas, Tehuacan, 

 alt. 2000 m., 22 June, 1968, C. Conzatti, no. 2221 (hb. Field Museum, 

 cat. no. 235157), fruiting specimen. Of the known species, E. tehuacana 

 is most nearly related to E. viscosa Fernald, from which it may be readily 

 distinguished by the more oblong leaves, larger flowers and less glandu- 

 lar tomentum; the calyx is nearly twice as large as in E. viscosa and 

 except for the ciliation it is essentially glabrous. 



Lithospermum Conzattii Greenman, sp. nov. 



Herbaceum perenne 3-4 dm. altum; caulibus basi lignosis erectis 

 vel adscendentibus hirsutis et subcrispo-strigosis; foliis sessilibus lan- 

 cfeolatis vel lanceolato-oblongis 1-7 cm. longis 4-14 mm. latis acutis 

 integris utrinque adpresso-tuberculato-hispidis supra atro-viridibus 

 subtus pallidioribus; racemis usque ad 13 cm. longis foliaceis; floribus 

 brevi-pedicellatis, pedicellis 2-5 mm. longis; calycis lobis lineari-lan- 

 ceolatis 5-7 mm. longis hirsutis; corolla tubiformi 8-10 mm. longa 

 externe pilosa 5-lobata, lobis subrotundatis; staminibus inclusis, 

 antheris subsessilibus ; nuculis ovoideis4-5mm. longis nitidis levibusque.

 Rob. from which it differs in having larger flowers and smooth nutlets .
