DANIEL: NEW AND RECONSIDERED MEXICAN ACANTHACEAE XII 
149 
Calyx 5-lobed, 5 mm long, lobes linear, 4.5 mm long, 1.1 mm wide, similar in size, abaxially 
pubescent like bracteoles. Corolla bright and shiny red to orange-red, 45-60 mm long, externally 
pubescent with erect to flexuose eglandular and glandular trichomes 0.1-0.8 mm long, tube 22-35 
mm long, 3.5-3.8 mm in diameter near midpoint, gradually expanded from base with no clear dis¬ 
tinction between a narrow proximal portion and a throat, upper lip 22-25 mm long, emarginate at 
apex with lobes to 0.2 mm long, lower lip recoiled, up to 25 mm long. Stamens 22-24 mm long, 
filaments red, glabrous distally, thecae parallel, unequally inserted (overlapping by 1.6-1.8 mm), 
2.5-2.7 mm long, ± equal in size, dorsally glabrous, lacking basal appendages; pollen oblate-spher¬ 
oidal, 5-aperturate, polar diameter 57 pm, equatorial diameter 58-63 pm insulae linked into 
5 loops, each of which surrounds a linear row or an elliptic band of insulae. Style 45-53 mm long, 
stigma equally 2-lobed, lobes 0.1 mm long. Capsule and seeds not seen. 
Phenology. — Flowering: April-May; fruiting: unknown. 
Distribution and habitat.— Southern Mexico (central southern Oaxaca; Fig. 1); plants 
occur very sporadically in evergreen seasonal forest (selva mediana perennifolia), and cafetales 
therein, at elevations from 950 to 1150 m. 
Conservation. — This species is known from two collections, both from Cerro Espino (Fig. 
3) some 200 meters apart in elevation, from which an EOO cannot be calculated. Daniel & de Avila 
12204 was collected along a trail in an overgrown and presumably abandoned (at least not main¬ 
tained) coffee plantation where fewer than 10 plants were seen. The precise location of the type 
collection from Cerro Espino is not known; an approximation of coordinates for it is indicated 
above. Although the species would appear to be both local and rare, there is insufficient data to 
make a preliminary assessment for it other than Data Deficient (DD). 
Illustrations. — Figures 3, 10. 
Paratype.— MEXICO. Oaxaca: western slope of Cerro Espino, 0.5-1.5 km E of Finca 
Monte Cristo (abandoned), which is 10 km (by road) E of Mex. Hwy. 175 at jet. of turn to Tolte- 
pec, 15°52.282'N, 096°25.042'W, T. Daniel & A. de Avila 12204 (CAS). 
Discussion. — Like that of Poikilacanthus foliosepalus, pollen reveals this species to be 
among those that pertain to Poikilacanthus as traditionally recognized (see discussion above under 
P. foliosepalus ). Unlike P foliosepalus, pollen of J. pochutlensis shows the second type described 
for the genus (Daniel 1991, 1998), that is, with the insulae sharing common endwalls and arranged 
in loops that enclose a row or band of insulae (Fig. 4G, H). 
The paratype was only in bud when collected (Fig. 3), but has an unopened corolla 60 mm long 
(vs. to 49 mm long on the holotype). 
New Combinations 
Justicia chrysostephana (Hook.f.) T.F. Daniel, comb. nov. 
Cyrtanthera chrysostephana Hook.f., Bot. Mag. 97: t. 5887. 1871. Jacobinia chrysostephana 
(Hook.f.) Benth. & Hook.f. ex Hemsl., Biol. Centr.-Amer. 2(12): 520. 1882. Type.— MEXICO. 
The description and illustration in the protologue are based on plants cultivated in England from 
materials imported from Mexico by Mr. Bull of Chelsea. A specimen at K (Fig. 11) that appears to 
represent original material bears Hooker’s name, an indication that it was cultivated from plants of 
Mexican origin by Bull in December 1870, and reference to the illustration (5887) in the Botani¬ 
cal Magazine — all of which appear to be in Hooker’s handwriting and conform to information in 
the protologue. This specimen is here treated as the holotype of this name. If it can be demonstrat¬ 
ed that it is not original material (i.e., if all of this information on the specimen at K was added to 
a specimen cultivated after publication of the name), then another possibility for a type would be 
to choose the color illustration (Fig. 11) with details from the protologue (t. 5887) as lectotype.
