ative to its congeners is ambiguous, depending on analytical method. Pollen of C. yucatanensis 
(Fig. 4A, B) conforms to that otherwise known for the genus (Daniel 1983, 1998). Macromorpho- 
logical differences between C. yucatanensis and C. myriantha (Standi.) Standi., the only other 
species of the genus to occur in the Yucatan Peninsula, were summarized by Daniel (1993) and 
Camevali F. et al. (2005). 
Justicia zapoteca T.F. Daniel, sp. nov. 
Justicia zapoteca can be distinguished by the following combination of characters: leaf blades 
with at least the adaxial surface pubescent; inflorescences of axillary and/or terminal, pedunculate, 
and dichasiate spikes or panicles of dichasiate spikes; calyces unequally five-lobed, with four lobes 
equal to subequal in size and the posterior lobe filiform and greatly reduced in size; corollas pale 
red-pink (salmon) to purplish, 25-32 mm long, and externally pubescent with glandular and eglan- 
dular trichomes; anther thecae superposed, perpendicular, dorsally pubescent, and the lower theca 
with a basal appendage 0.3-0.5 mm long; pollen two-aperturate with apertures flanked on each side 
by two rows of insulae (and sometimes peninsulae as well); capsules 12-16 mm long and pubes¬ 
cent with glandular an eglandular trichomes; and seeds with the testa tuberculate and with the 
tubercles granulate.

Trailing perennial herbs to erect shrubs to 3 m; young stems subquadrate and substriate to stri¬ 
ate, intemodes glabrous or sparsely 2-fariously pubescent with flexuose to antrorsely and/or 
retrorsely appressed eglandular trichomes to 0.7 mm long, nodes and axillary buds pubescent with 
eglandular trichomes. Leaves petiolate, petioles to 55 mm long, blades ovate to elliptic, 42-170 
mm long, 22-101 mm wide, 1.6-2.8 x longer than wide, (rounded to) acute to acuminate at apex, 
truncate to rounded to acute to subattenuate at base, adaxial surface pubescent with antrorse to 
antrorsely appressed eglandular trichomes restricted to major veins or to midvein only, abaxial sur¬ 
face glabrous or very sparsely pubescent like adaxial surface, margin entire. Inflorescence of axil¬ 
lary and/or terminal pedunculate dichasiate spikes or panicles of dichasiate spikes to 120 mm long 
(including peduncle and excluding flowers), peduncles to 13 mm long, glabrous or evenly puberu- 
lent with erect eglandular and subglandular trichomes to 0.05 mm long (puberulent) and sometimes 
also with an overstory of erect to flexuose eglandular trichomes to 0.7 mm long , bracts subtend¬ 
ing panicle branches ovate to linear-elliptic to subulate, 3-8 mm long, 0.3-3 mm wide; fertile por¬ 
tion of individual spikes to 87 mm long and 2-3 mm wide (excluding corollas), rachis clearly vis¬ 
ible, evenly puberulent and usually also with an overstory of erect glandular trichomes 0.1 mm long 
(especially distally) and sometimes also with erect to flexuose eglandular trichomes (sometimes 
sparse) 0.1-0.5 mm long, or sometimes glabrous proximally; dichasia alternate (1 per node), 
± secund, sessile, 1-flowered. Bracts not imbricate, opposite, subulate to lance-subulate, 2-3 mm 
long, 0.3-0.6 mm wide, abaxial surface pubescent like rachis. Bracteoles linear-subulate to lance- 
subulate, 1.8-2.6 mm long, 0.3-0.5 mm wide, abaxial surface pubescent like bracts. Flowers ses¬ 
sile to subsessile (i.e., pedicels to 0.5 mm long). Calyx 5-lobed, 3.5-6 mm long, abaxially pubes¬ 
cent like bracteoles, lobes heteromorphic (4+1, posterior lobe reduced), 4 lobes equal to subequal 
in size, lanceolate, 3-5 mm long, 0.6-1 mm wide, widest near base or midpoint, posterior lobe 
inconspicuous, filiform, 0.4-2 mm long, 0.05-0.2 mm wide. Corolla pale red-pink (salmon) to pur¬ 
plish, 25-32 mm long, externally pubescent with erect to flexuose eglandular and glandular (some-
