FL, Keys, 20061213
South Key Largo, few flowers.
Walking up to Doc's Diner and back.
Richardia grandiflora []
Large patch somewhere around milepost 97 or so, between path and hwy. Coming into full flower.
| | GEN | | herb, sprawling, d spreading hirsute and min curly strig |
| | LF | | opp, entire, 25x10+5mm or so, oblance-ellip, stips form fibrillate sheath, ocreal bristles 3mm & red, hairy |
| | INFL | | term involucrate head |
| | SEP | | 6, joined at base, min bristly esp ab, 3x1mm, delt |
| | PET | | 6, joined, funnel-shaped, tube 10mm, lobes ov & 5x3mm, lilac to pinkish lobes with lines ext down into white funnel a little |
| | STAM | | 6, att in sinuses, fil 1mm, anth 1.5mm, white |
| | OV | | inf, 3 mericarps joined to central post |
| | STYLE | | 1, 3 forks, 10mm + 2mm forks, white, attached inside green pillowy ring at base |
| | FR | | 2x2mm, round, v 3-lobed, conspic tuberculate |
| | SEED | | 1.5mm, oblong prism, grooved inside |
Convolvulaceae []
Scattered, some large patches, closer to milepost 99-100, along path and road. In full flower, but closes tight so quickly after picking that it's hard to dissect.
| | GEN | | herb, sprawling, mostly glab |
| | LF | | strongly sagittate, glab and even sl glauc bel, sp short bristly ab, trich simple |
| | INFL | | small cyme or pan, scale-like bracts, tuberculate |
| | SEP | | long pilose bel half with abupt distinct bulb bases, ~7mm long |
| | PET | | pinkish purplish, ~15mm long, funnelform, glab to sl sh hirsute inside bel where stam attach |
| | STAM | | 5, attach around base of ov, sp min hairy bel |
| | OV | | 1, sup, 3 ovules, v d long silky erect hairy |
| | STYLE | | 1, two-lobed at tip, stigmas compact |
Fails to key to genus convincingly: 3 seeds, 1 style, scale-like bracts, uniform sepals, and simple trichomes gets you to I. purpurea, I. hederacea (both are way off), and M. umbellata (but I don't see the anthers twisting).
Chamaesyce hypericifolia []
Some large sub-bushes with 1/4" trunks and maybe 3-4' high. At edge of fence of fallow lot near milepost 100 or so. Key characters I used to verify ID:
| | STIP | | joined, conspic, red |
| | INFL | | tight br'd cluster (with some tin scale-like bracts in there) in a few axils near br tips| apps | | 1mm or so, white, rounded |
|
Chamaesyce mendezii []
Dense fuzzy-looking v flat lawn cover near milepost 100 or so.
| | GEN | | ann, creeping, sev sts from rootstock |
| | ST | | hairy only ab and esp on sides, strig ab, more spreading on angles, sl flattened in x-sect |
| | LF | | ellip-oblong, 6x3+0.5mm, glab |
| | STIP | | sep ab and fused bel, 1.6-1.7mm and shallowly lacerate bel |
| | INFL | | 1 per axil esp near tips| apps | | white, 1-3 rounded teeth, conspic |
|
| | FR | | hispid, more hair on angles but also on faces, 1.2mm, lobed |
| | STYLE | | v short and curved up |
Is this
C. maculata or
C. mendezii??
