	 EL AMBIENTE FÍSICO/THE PHYSICAL ENVIRONMENT. Yes, we are proposing a small correction to our “Introducción” (Manual Vol. 1). On p. 53 (p. 52 of the Spanish text), we indicate that the maximum elevation of the Península de Nicoya is 983 m. This happens to be the elevation at the  summit of Cerro Vista al Mar, the highest peak of the main axial ridge of the  peninsula, to which all eyes are involuntarily drawn as the chief eminence, and  which we had logically concluded to represent exactly that, following a cursory  check of all relevant topographic maps to eliminate other possibilities. Our Gazetteer baldly anoints Cerro Vista al  Mar as “the highest point on the peninsula” (a statement that persists even in  the new revision). Nevertheless, it is  all a lie! While researching localities  on the Península de Nicoya in connection with his taxonomic work, Manual co-PI Barry Hammel chanced to encounter a peak of 1018 m elevation, at approximately 9º57’N and  85º17’W, on the Cerro Azul quadrangle.  Why had we never noticed this peak before? First, it is located in a region that lacks  other notably high summits (we could find no others in the near vicinity  attaining even 850 m), so our eyes were not drawn to the general area. Second, and most significantly, the peak has  no name, being marked on the map simply by an unobtrusive benchmark named  “Azul.” It is probably for these same  reasons that no one else has noticed this error and called us on it during the  past nine years (that, and the fact that nobody reads this sludge we churn  out!). We propose to call this spurned  peak “Cerro Azul,” since that is the name of the benchmark, the quadrangle, and  a village about 3 km to the southwest; plus, we imagine that “Cerro Azul” is  the name used for this peak by local residents, even if it is not recorded adequately  on the topographical map. Note, however,  that the place-name “Cerro Azul” (whether in reference to the peak or the town)  has not been included in our Gazetteer (including the new revision), because we  have never seen it used on a herbarium label.  We hope to change that circumstance in the near future. 
    
    CONVOLVULACEAE. Manual co-PI Barry Hammel has happened upon an embarrassing oversight in his own Manual treatment for  this family: the Costa Rican  distribution of Ipomoea ramosissima (Poir.) Choisy fails to account for the type locality of one of its listed  synonyms, I. quesadana Standl. The latter name was based on a specimen  collected (as we might have guessed from its epithet!) at Villa (Ciudad)  Quesada, on the Atlantic slope of the Cordillera Central. Thus, the distribution statement for I. ramosissima should be reconfigured as  follows: “vert. Carib. Cord. de Tilarán, ambas verts. Cords. de  Guanacaste y Central, vert. Pac., P.N.  Carara.” No changes are indicated for  the life zones or elevational range. The  blame for this oversight falls equally (if not more heavily) on the shoulders  of co-PI Mike Grayum, who is  generally encharged with checking these type localities. On a similar note, Manual users should delete  the “+” from the elevational range of Ipomoea sp. A, which is only known (at least for the time being) from Cerro Vista al  Mar (maximum elevation 983 m; see the foregoing entry). 
    LORANTHACEAE. Minor upheaval in Struthanthus! One thing leads to another, and a card house  (okay, a card hut) comes tumbling down.  This all started when we discovered that the specimen G. Herrera 3326, which had been  determined in TROPICOS as Struthanthus  burgeri Kuijt, is actually a paratype of S. acostensis L. A. González & J. F. Morales, and that the label  data of the specimen in question were unaccounted for in the  distribution/phenology summary of the latter sp. in the Manual (Vol. 6). Worse yet, it turns out that the Herrera  specimen is our cited voucher for S.  burgeri! How did this happen? In the first place, your errant editors  probably overlooked the inconspicuous paratype citation on the fourth page of  the protologue of S. acostensis; and  in the second place, in their haste to avoid citing the type of S. burgeri, said editors must have  replaced it uncritically with the misidentified specimen under discussion. The result of all this is that the Manual  distribution/phenology summaries (as well as the voucher citations) for both S. acostensis and S. burgeri need to be modified; we here offer amended paragraphs,  taking the opportunity to flesh them out with additional data not previously  available to us: 
	
    Struthanthus acostensis: Bosque muy húmedo y pluvial,  bosques primarios y sitios alterados, 700–1150+ m; vert. Carib. E Cord. de  Talamanca, vert. Pac. Cord. de Talamanca, Cerro Turrubares, S Fila Costeña  (Fila Cruces). Fl. abr., may., jul. ENDÉMICA.  (G. Herrera 3326; INB, MO) 
	Struthanthus burgeri: Bosque muy húmedo, bosques y potreros,  750–850 m; vert. Pac., N Fila Costeña.  Fl. feb. CR, Ecua. (Lobo  et al. 288; CR, MO) 
    
	The Lobo specimen is the only available Costa Rican voucher for Struthanthus burgeri other than the  type. If confirmed, the Ecuadorian  record (a recent identification in TROPICOS by family specialist Job Kuijt) signifies the loss of  another Costa Rican endemic. Host data  are still lacking for both of the spp. under consideration.
